前言
首先，跟守护在作者公众号和私信作者催更的朋友们道个歉。疫情的原因，公司从年初到现在一直处于996+的高压模式，导致公众号更新频率较低。而且作者每更新一篇原创公众号，既要对自己沉淀知识负责，也要对愿意和作者一起探讨一起学习一起进步的小伙伴儿们负责，防止误人子弟。所以作者的每一篇原创，都是作者在有限时间内仔细推敲后的产物，希望大家可以理解。
Talk is Cheap!
前面分享的几个章节，差不多把实际用到的控件和容器的封装、扩展、重绘都举例到了(后续如果还有其他特例，作者也会更新进来)。今天要分享的依然是“Fucking ERP”系列中比较重要的环节——流程图。
本章的流程图并非工作流，winform在市面上有很多经典的工作流组件比如微软的WWF，还有很多开源自主研发的工作流组件等等，后续作者实际用到的话也会分享出来和大家一起探讨。此处分享的流程图，主要是"标识"的作用，主要用来表示业务数据的流转，具体数据如何流转，都需要各位后台自行处理（说白了，就是从A表查出数据，插入到B表，然后更新A表标识罢了。）
Show me the Code!
首先，界面加载的时候，初始化控件可用性，以及所有模块列表
private void frmWorkFlow_Load(object sender, EventArgs e) { //创建大模块 CreateModule(); this.TabPage1.PageVisible = false; this.TabPage2.PageVisible = false; this.TabPage3.PageVisible = false; this.kzxsBtnAddButton.Enabled = false; this.kzxsBtnAddLabel.Enabled = false; this.kzxsBtnAddLine.Enabled = false; this.Btn_SaveButton.Enabled = false; this.Btn_SaveLabel.Enabled = false; this.Btn_SaveLine.Enabled = false;
为了满足演示效果，本位都用DataTable来模拟数据库操作。初始化模块菜单方法如下：
//创建主目录 public void CreateModule() { //此处拿DataTable来存储数据库的所有菜单节点，此处用销售模块来举例 DataTable dtSalesOrder = new DataTable(); dtSalesOrder.Columns.Add("sID", typeof(Guid)); dtSalesOrder.Columns.Add("sModel", typeof(string)); dtSalesOrder.Columns.Add("iOrder", typeof(int)); dtSalesOrder.Rows.Add(new object[] { Guid.NewGuid(), "销售模块", 1 }); DataRow[] dr = dtSalesOrder.Select("", "iOrder"); //存在子菜单生产树结构 if (dr.Length > 0) { foreach (DataRow row in dr) { DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton(); sb.Name = row["sID"].ToString(); sb.Text = row["sModel"].ToString(); sb.Tag = row["sModel"].ToString(); sb.TabIndex = int.Parse(row["iOrder"].ToString()); sb.Dock = DockStyle.Top; sb.Height = 25; sb.Click += onBtnClick; panelControl1.Controls.Add(sb); } } }
模块按钮绑定了点击事件，用于触发当前选择的菜单的流程图（代码逻辑已经添加，时间有限，本文不做处理，如有疑问，可公众号私信作者一起探讨）
private void onBtnClick(object sender, EventArgs e) { sModel = ((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim(); sModelName = ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim(); //根据选择的菜单模块，加载当前菜单的流程图 CreateFlowMap(((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim(), ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim()); }
创建流程图部分方法如下（有需要源码可关注作者公众号，私信作者免费获取）：
//创建流程图 public void CreateFlowMap(string sModelID, string sModelName) { //查找是否存在流程图 string sFilter = "sModelCode = '" + sModelID + "'"; TabControl2.Visible = true; Boolean bExists = false; //查找模块流程图是否存在 foreach (DevExpress.XtraTab.XtraTabPage tabPage in TabControl2.TabPages) { if (tabPage.Name == sModelID) { tabPage.PageVisible = true; TabControl2.SelectedTabPage = tabPage; bExists = true; } else { tabPage.PageVisible = false; } } //不存在需要增加页面 if (!bExists) { .....
You say a JB without pictures ！无图言X，先给大家看看设计图
图片展示解析：
1.左侧栏初始化动作，加载所有系统模块
2.右侧上部分为操作栏，设计按钮处理当前选中的菜单模块，用于加载/新增/删除当前模块的流程图
3.右侧左边部分为绘制工具栏，此处只拿绘制直线(或带箭头的直线),Label（流程注释），按钮来举例子。
4.右侧下部分为绘制工具栏的属性配置，点击保存，呈现绘制结果如图右侧中间部分
5.流程图展示区，用于加载或绘制流程图
（以上因篇幅和时间限制未做详细测试，主要实现功能为主举个例子，作者绘制期间也有遇到不完善的地方，后续有时间在优化）
代码没有太大难度(需要源码研究可关注作者公众号，私信作者免费获取)，主要跟大家分享下绘制流程模块吧。
(带箭头的)直线的绘制
Talk is Cheap,直接上代码：
KzxLine line = new KzxLine(); bAddLine = true; line.Name = "Line"; line.Tag = ""; line.lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString()); string sColor = this.cmb_ColorLine.Text.ToString().Trim(); switch (sColor) { case "Black": line.LineColor = KzxLine.ColorType.Black; break; case "Blue": line.LineColor = KzxLine.ColorType.Blue; break; case "Green": line.LineColor = KzxLine.ColorType.Green; break; case "Lime": line.LineColor = KzxLine.ColorType.Lime; break; case "Red": line.LineColor = KzxLine.ColorType.Red; break; case "Yellow": line.LineColor = KzxLine.ColorType.Yellow; break; default: line.LineColor = KzxLine.ColorType.Black; break; } line.IsSolid = !this.chk_Solid.Checked; switch (this.cmb_ArrowType.Text.ToString().Trim()) { case "Start": line.ArrowPosition = KzxLine.ArrowType.Start; break; case "End": line.ArrowPosition = KzxLine.ArrowType.End; break; case "All": line.ArrowPosition = KzxLine.ArrowType.All; break; case "None": line.ArrowPosition = KzxLine.ArrowType.None; break; } if (this.chk_Horizon.Checked) { line.LineStyle = KzxLine.LineType.Horizontal; line.Left = int.Parse(this.edt_LeftLine.Text.ToString()); line.Top = int.Parse(this.edt_TopLine.Text.ToString()); line.Width = int.Parse(this.edt_WidthLine.Text.ToString()); line.Height = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; } else { line.LineStyle = KzxLine.LineType.Vertical; line.Left = int.Parse(this.edt_LeftLine.Text.ToString()); line.Top = int.Parse(this.edt_TopLine.Text.ToString()); line.Width = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; line.Height = int.Parse(this.edt_HeightLine.Text.ToString()); } line.Visible = true; line.Click += onClick; MoveClass.BarcodeControl(line); if (bFirstControl) { MoveClass.BarcodeCreate(); bFirstControl = false; } this.TabControl2.Enabled = true; this.TabControl1.SelectedTabPage = TabPage3; this.TabPage3.PageVisible = true; this.kzxsBtnAddButton.Enabled = true; this.kzxsBtnAddLabel.Enabled = true; this.kzxsBtnAddLine.Enabled = true;
其中KzxLine是作者封装的用户控件,（如有需要，请关注公众号私信作者，源码免费赠送）部分代码如下：
protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); //e.Graphics.DrawLine(new Pen(lineColor, lineHeight), 1, 1, this.Width, lineHeight); AdjustableArrowCap lineCap = new AdjustableArrowCap(5, 5, true); Pen p = new Pen(lineColor, 1); string sColor = ""; if ((int)color == 0) { sColor = "Black"; } if ((int)color == 1) { sColor = "Red"; } if ((int)color == 2) { sColor = "Yellow"; } if ((int)color == 3) { sColor = "Blue"; } if ((int)color == 4) { sColor = "Green"; } if ((int)color == 5) { sColor = "Lime"; } p.Color = Color.FromName(sColor); p.Width = LWidth; if ((int)ArrowP == 1) { p.CustomStartCap = lineCap; } else if ((int)ArrowP == 2) { p.CustomEndCap = lineCap; } else if ((int)ArrowP == 3) { p.CustomStartCap = lineCap; p.CustomEndCap = lineCap; } if (!Solid) { float[] dashValues = { 5, 2, 5, 2 }; p.DashPattern = dashValues; } int iLeft = 1; int iTop = 1; int iWidth = 1; int iHeight = 1; if ((int)sTyle == 0) { iLeft = 1; iTop = LWidth * 2 + 5; iWidth = this.Width; iHeight = LWidth * 2 + 5; } else { iLeft = LWidth * 2 + 5; iTop = 1; iWidth = LWidth * 2 + 5; iHeight = this.Height; } e.Graphics.DrawLine(p, iLeft, iTop, iWidth, iHeight); p.Dispose(); }
点击如图"箭头/直线"按钮后，下面会显示控件的属性配置区域，设置好后点击保存，就会把绘制好的控件添加到流程图展示区。保存事件如下：
private void Btn_SaveLine_Click(object sender, EventArgs e) { if (bAddLine) { KzxLine line = new KzxLine(); line.Name = "Line"; line.Tag = ""; line.lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString()); string sColor = this.cmb_ColorLine.Text.ToString().Trim(); switch (sColor) { case "Black": line.LineColor = KzxLine.ColorType.Black; break; case "Blue": line.LineColor = KzxLine.ColorType.Blue; break; case "Green": line.LineColor = KzxLine.ColorType.Green; break; case "Lime": line.LineColor = KzxLine.ColorType.Lime; break; case "Red": line.LineColor = KzxLine.ColorType.Red; break; case "Yellow": line.LineColor = KzxLine.ColorType.Yellow; break; default: line.LineColor = KzxLine.ColorType.Black; break; } line.IsSolid = !this.chk_Solid.Checked; switch (this.cmb_ArrowType.Text.ToString().Trim()) { case "Start": line.ArrowPosition = KzxLine.ArrowType.Start; break; case "End": line.ArrowPosition = KzxLine.ArrowType.End; break; case "All": line.ArrowPosition = KzxLine.ArrowType.All; break; case "None": line.ArrowPosition = KzxLine.ArrowType.None; break; } if (this.chk_Horizon.Checked) { line.LineStyle = KzxLine.LineType.Horizontal; line.Left = int.Parse(this.edt_LeftLine.Text.ToString()); line.Top = int.Parse(this.edt_TopLine.Text.ToString()); line.Width = int.Parse(this.edt_WidthLine.Text.ToString()); line.Height = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; } else { line.LineStyle = KzxLine.LineType.Vertical; line.Left = int.Parse(this.edt_LeftLine.Text.ToString()); line.Top = int.Parse(this.edt_TopLine.Text.ToString()); line.Width = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; line.Height = int.Parse(this.edt_HeightLine.Text.ToString()); } line.Visible = true; line.Click += onClick; MoveClass.BarcodeControl(line); if (bFirstControl) { MoveClass.BarcodeCreate(); bFirstControl = false; } this.TabControl2.Enabled = true; bAddLine = false; TabControl2.SelectedTabPage.Controls.Add(line); this.kzxsBtnAddButton.Enabled = true; this.kzxsBtnAddLabel.Enabled = true; this.kzxsBtnAddLine.Enabled = true; this.sBtnDelete.Enabled = true; } else if ((selectControl is KzxLine) && (KzxLine)selectControl != null) { ((KzxLine)selectControl).lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString()); string sColor = this.cmb_ColorLine.Text.ToString().Trim(); switch (sColor) { case "Black": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Black; break; case "Blue": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Blue; break; case "Green": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Green; break; case "Lime": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Lime; break; case "Red": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Red; break; case "Yellow": ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Yellow; break; default: ((KzxLine)selectControl).LineColor = KzxLine.ColorType.Black; break; } ((KzxLine)selectControl).IsSolid = !this.chk_Solid.Checked; switch (this.cmb_ArrowType.Text.ToString().Trim()) { case "Start": ((KzxLine)selectControl).ArrowPosition = KzxLine.ArrowType.Start; break; case "End": ((KzxLine)selectControl).ArrowPosition = KzxLine.ArrowType.End; break; case "All": ((KzxLine)selectControl).ArrowPosition = KzxLine.ArrowType.All; break; case "None": ((KzxLine)selectControl).ArrowPosition = KzxLine.ArrowType.None; break; } if (this.chk_Horizon.Checked) { ((KzxLine)selectControl).LineStyle = KzxLine.LineType.Horizontal; ((KzxLine)selectControl).Left = int.Parse(this.edt_LeftLine.Text.ToString()); ((KzxLine)selectControl).Top = int.Parse(this.edt_TopLine.Text.ToString()); ((KzxLine)selectControl).Width = int.Parse(this.edt_WidthLine.Text.ToString()); ((KzxLine)selectControl).Height = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; } else { ((KzxLine)selectControl).LineStyle = KzxLine.LineType.Vertical; ((KzxLine)selectControl).Left = int.Parse(this.edt_LeftLine.Text.ToString()); ((KzxLine)selectControl).Top = int.Parse(this.edt_TopLine.Text.ToString()); ((KzxLine)selectControl).Width = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10; ((KzxLine)selectControl).Height = int.Parse(this.edt_HeightLine.Text.ToString()); } } }
因所有绘制控件都绑定了拖拽事件，所以可以在流程图展示区随意拖拽部署显示控件（效果见下图）。
Label(注释)控件封装
/// <summary> /// 标签验证 /// </summary> public partial class KzxLabel : KzxBaseControl
Label无需重绘只需封装，初始化绑定多语言即可。
public void LayoutControl() { BindingEvent(this, PluginInfoTable); if (this.DesignMode == true) { this.DesigeCaption = GetLanguage(this.MessageCode, this.DesigeCaption); } } /// <summary> /// 绑定事件 /// </summary> /// <param name="eventInfoTable">事件信息表</param> public override void BindingEvent(DataTable eventInfoTable) { BindingEvent(this, eventInfoTable); } private void KzxLabel_Load(object sender, EventArgs e) { LayoutControl(); //UpdateDelegate d = LayoutControl; //this.BeginInvoke(d); }
按钮控件封装
按钮的封装同上Label一样，具体请移步《玩转控件:扩展Dev中SimpleButton》.或者直接用Dev原生的SimpleButton亦可，此处不做过多废话。只需在属性配置区域的保存事件中，添加到流程图展示区即可，配置区的按钮保存代码如下：
BillInfo info = new BillInfo(); //info.sID = Edt_FrmBtn.EditValue.ToString(); info.sFrmName = Edt_FrmBtn.Text.ToString(); info.sFrmCaption = Edt_CaptionBtn.Text.Trim(); info.sMsgID = Edt_MsgBtn.Text.ToString().Trim(); if (bAddBtn) { DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton(); sb.Left = int.Parse(Edt_LeftBtn.Text.Trim()); sb.Top = int.Parse(Edt_TopBtn.Text.Trim()); sb.Width = int.Parse(Edt_WidthBtn.Text.Trim()); sb.Height = int.Parse(Edt_HightBtn.Text.Trim()); sb.Name = Edt_FrmBtn.Text.Trim(); sb.Text = Edt_CaptionBtn.Text.Trim(); sb.Tag = info; sb.Image = picture1.Image; sb.ImageLocation = DevExpress.XtraEditors.ImageLocation.TopCenter; sb.Cursor = Cursors.Hand; sb.Visible = true; TabControl2.SelectedTabPage.Controls.Add(sb); sb.Click += onClick; MoveClass.BarcodeControl(sb); if (bFirstControl) { MoveClass.BarcodeCreate(); bFirstControl = false; } this.TabControl2.Enabled = true; bAddBtn = false; this.kzxsBtnAddButton.Enabled = true; this.kzxsBtnAddLabel.Enabled = true; this.kzxsBtnAddLine.Enabled = true; } else if ((selectControl is DevExpress.XtraEditors.SimpleButton) && (DevExpress.XtraEditors.SimpleButton)selectControl != null) { ((DevExpress.XtraEditors.SimpleButton)selectControl).Left = int.Parse(Edt_LeftBtn.Text.Trim()); ((DevExpress.XtraEditors.SimpleButton)selectControl).Top = int.Parse(Edt_TopBtn.Text.Trim()); ((DevExpress.XtraEditors.SimpleButton)selectControl).Width = int.Parse(Edt_WidthBtn.Text.Trim()); ((DevExpress.XtraEditors.SimpleButton)selectControl).Height = int.Parse(Edt_HightBtn.Text.Trim()); ((DevExpress.XtraEditors.SimpleButton)selectControl).Name = Edt_FrmBtn.Text.Trim(); ((DevExpress.XtraEditors.SimpleButton)selectControl).Text = Edt_CaptionBtn.Text.Trim(); ((DevExpress.XtraEditors.SimpleButton)selectControl).Tag = info; ((DevExpress.XtraEditors.SimpleButton)selectControl).Image = picture1.Image; ((DevExpress.XtraEditors.SimpleButton)selectControl).ImageLocation = DevExpress.XtraEditors.ImageLocation.TopCenter; ((DevExpress.XtraEditors.SimpleButton)selectControl).Cursor = Cursors.Hand; }
以上便是"箭头/直线","Label注释","按钮"等功能的准备工作，具体效果如图：
再次强调，因时间和篇幅问题，作者没有对代码做严格的校验，主要以实现功能为主。所以当您拿到源码时需要根据实际情况自行完善，或者后续作者有时间也会继续完善（工作996+的我太难了！）
各个模块功能实现后，就是保存当前绘制的流程图环节了，为了演示效果，作者没有处理数据库相关的工作，主要以DataTable来存储相关绘制数据的。至于图片，作者是用流的方式来存储的，展示时解析即可。
#region 图片处理 /// <summary> /// 点击上传图片 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void picture1_Click(object sender, EventArgs e) { if (this.openDialog1.ShowDialog() == DialogResult.OK) { picture1.Image = Image.FromFile(this.openDialog1.FileName); } } /// <summary> /// 用流的方式来存储图片 /// </summary> /// <param name="img"></param> /// <returns></returns> private byte[] convertByte(Image img) { MemoryStream ms = new MemoryStream(); img.Save(ms, img.RawFormat); byte[] bytes = ms.ToArray(); ms.Close(); return bytes; } private Image convertImg(byte[] datas) { MemoryStream ms = new MemoryStream(datas); Image img = Image.FromStream(ms, true); ms.Close(); return img; } #endregion
DataTable数据存储如下图：
大家可以根据自己实际情况，存储到数据库或者配置文件中，具体保存代码如下：
int iOrder = 0; foreach (Control c in TabControl2.SelectedTabPage.Controls) { //string sID = ""; string sFrmName = ""; string sCaption = ""; string sType = ""; string sBtnPositon = ""; string sArrowType = ""; string sFrmType = ""; string sMsgID = ""; string sColor = ""; Boolean bSolid = true; Boolean bUnderLine = false; Boolean bHorzion = true; int iLeft = 0; int iTop = 0; int iWidth = 0; int iHeight = 0; int iLineWidth = 0; float iFontSize = 0; BillInfo info = c.Tag as BillInfo; if (c is DevExpress.XtraEditors.SimpleButton) { //Button按钮 //sID = info.sID; sFrmName = c.Name.ToString().Trim(); sCaption = c.Text.ToString().Trim(); sFrmType = info.sFrmType; sMsgID = info.sMsgID; sType = "Btn"; iLeft = c.Left; iTop = c.Top; iWidth = c.Width; iHeight = c.Height; sBtnPositon = "TopCenter"; } else if (c is DevExpress.XtraEditors.LabelControl) { //Label控件 //sID = info.sID; sFrmName = c.Name.ToString().Trim(); sCaption = c.Text.ToString().Trim(); sFrmType = info.sFrmType; sMsgID = info.sMsgID; sType = "Label"; iLeft = c.Left; iTop = c.Top; iWidth = c.Width; iHeight = c.Height; if (c.Font.Underline) //下划线 { bUnderLine = true; } iFontSize = ((DevExpress.XtraEditors.LabelControl)c).Font.Size; //字体大小 sColor = ((DevExpress.XtraEditors.LabelControl)c).ForeColor.Name.ToString(); //字体颜色 } else if (c is KzxLine) { sCaption = "Line"; sType = "Line"; if (((KzxLine)c).ArrowPosition == KzxLine.ArrowType.Start) { sArrowType = "Start"; } else if (((KzxLine)c).ArrowPosition == KzxLine.ArrowType.End) { sArrowType = "End"; } else if (((KzxLine)c).ArrowPosition == KzxLine.ArrowType.All) { sArrowType = "All"; } else if (((KzxLine)c).ArrowPosition == KzxLine.ArrowType.None) { sArrowType = "None"; } //颜色 if (((KzxLine)c).LineColor == KzxLine.ColorType.Black) { sColor = "Black"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Blue) { sColor = "Blue"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Green) { sColor = "Green"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Lime) { sColor = "Lime"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Red) { sColor = "Red"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Yellow) { sColor = "Yellow"; } else if (((KzxLine)c).LineColor == KzxLine.ColorType.Black) { sColor = "Black"; } iLineWidth = ((KzxLine)c).lineWidth; if (!((KzxLine)c).IsSolid) { bSolid = false; } if (((KzxLine)c).LineStyle == KzxLine.LineType.Horizontal) { bHorzion = true; iLeft = ((KzxLine)c).Left; iTop = ((KzxLine)c).Top + ((KzxLine)c).lineWidth * 2 + 5; iWidth = ((KzxLine)c).Width + ((KzxLine)c).Left; iHeight = ((KzxLine)c).Top + ((KzxLine)c).lineWidth * 2 + 5; } else { bHorzion = false; iLeft = ((KzxLine)c).Left + ((KzxLine)c).lineWidth * 2 + 5; iTop = ((KzxLine)c).Top; iWidth = ((KzxLine)c).Left + ((KzxLine)c).lineWidth * 2 + 5; iHeight = ((KzxLine)c).Top + ((KzxLine)c).Height; } //gc[i] = c; } if ((c is DevExpress.XtraEditors.SimpleButton) || (c is DevExpress.XtraEditors.LabelControl) || (c is KzxLine)) { DataRow newRow = dtDesign.NewRow(); newRow["uGuid"] = Guid.NewGuid().ToString("D"); newRow["sModelCode"] = sModel; //newRow["sID"] = sID; newRow["sFrmName"] = sFrmName; newRow["sCaption"] = sCaption; newRow["sType"] = sType; newRow["iLeft"] = iLeft; newRow["iTop"] = iTop; newRow["iWidth"] = iWidth; newRow["iHeight"] = iHeight; newRow["sBtnPositon"] = sBtnPositon; newRow["sArrowType"] = sArrowType; if (c is DevExpress.XtraEditors.SimpleButton) { if (((DevExpress.XtraEditors.SimpleButton)c).Image != null) newRow["mImage"] = convertByte(((DevExpress.XtraEditors.SimpleButton)c).Image); } else { newRow["mImage"] = null; } //newRow["mImage"] = sModel; newRow["iOrder"] = iOrder; newRow["bActive"] = 1; newRow["sFrmType"] = sFrmType; newRow["sMsgID"] = sMsgID; newRow["sColor"] = sColor; newRow["iLineWidth"] = iLineWidth; newRow["iFontSize"] = iFontSize; newRow["sSysMode"] = ""; newRow["bSolid"] = bSolid; newRow["bUnderLine"] = bUnderLine; newRow["bHorizon"] = bHorzion; dtDesign.Rows.Add(newRow); iOrder = iOrder + 1; } } //TODO:保存到数据库操作 this.Btn_SaveButton.Enabled = false; this.Btn_SaveLabel.Enabled = false; this.Btn_SaveLine.Enabled = false; bDesign = false; bAddBtn = false; bAddLabel = false; bAddLine = false; this.Btn_Design.Enabled = true; this.Btn_Post.Enabled = false; this.kzxsBtnAddButton.Enabled = false; this.kzxsBtnAddLabel.Enabled = false; this.kzxsBtnAddLine.Enabled = false; this.Btn_Cancel.Enabled = false; this.TabControl2.Enabled = true; //TODO:从数据库加载数据流并绑定数据 this.TabControl2.TabPages.Remove(this.TabControl2.SelectedTabPage); CreateFlowMap(sModel, sModelName);
如上代码TODO出需要根据自己实际完善，或者公众号私信作者一起探讨。
至此工作完成！一起来看看最终效果：
