DEV控件：gridControl常用属性设置
2011-01-19 09:50
1.隐藏最上面的GroupPanel gridView1.OptionsView.ShowGroupPanel=false;
2.得到当前选定记录某字段的值 sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();
3.数据只读 gridView1.OptionsBehavior.Editable=false;
4.不显示MasterDetailView gridView1.OptionsDetail.EnableMasterViewMode=false;
5.修改最上面的GroupPanel内容 gridView1.GroupPanelText="柳生飘絮";
6.设置数据源: gridControl1.DataSource = dt; 绑定每一列的FiledName--属性 对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.
7.读写拷贝权限设置 只读不可拷贝： ColumnViewOptionsBehavior.Editable = False
只读可拷贝: ColumnViewOptionsBehavior.Editable = True OptionsColumn.AllowEdit = True OptionsColumn.ReadOnly = True
可编辑: ColumnViewOptionsBehavior.Editable = True OptionsColumn.AllowEdit = True OptionsColumn.ReadOnly = False
8.模板列的设置: 到Columns中，在他的属性中找到ColumnEdit. 以LookUpEdit为例： 首先从Designer左边菜单In-PlaceEditor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空. AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为True. SearchMode设置为OnlyInPopup. 然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1) 最后我们还要在代码里面给Re1绑定数据源和显示项. Re1.DataSource =DALUse.Query("select fid,fname,fsex from dual").Tables[0]; Re1.DisplayMember ="FSEX"; Re1.ValueMember ="FNAME";
9.设某一列文字和标题局中显示 gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center; gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;
10.去掉某一列上面的自动筛选功能(Filter) gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false; gridView1.Columns[0].OptionsFilter.AllowFilter =false; gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter =false;
11.设置冻结列(左冻结) gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;
12.得到单元格数据(0行0列) string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]); string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);
13.设置单元格数据(将0行0列的单元格赋值123) gridView1.SetRowCellValue(0, gridView1.Columns[0],"123");
13.手动添加dev的列 DevExpress.XtraGrid.Columns.GridColumn Col1=newDevExpress.XtraGrid.Columns.GridColumn (); Col1.FieldName="FID"; Col1.Visible=true; Col1.VisibleIndex=gridView1.Columns.Count; gridView1.Columns.Add(Col1);
14.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator
private void gridview_CustomDrawRowIndicator(objectsender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) { if (e.Info.IsRowIndicator &&e.RowHandle >= 0) e.Info.DisplayText = (e.RowHandle + 1).ToString(); }
15.删除: (修改了dgvdel里的datagridviewdel方法) public static voiddatagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv) { if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示",MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes) { intiSelectRowCount = Mydgv.SelectedRowsCount; if(iSelectRowCount > 0) { Mydgv.DeleteSelectedRows(); } } } 16. 新增: (对于新增,其本身的AddNewRow方法就可以做到) private void btn_add_Click(object sender, EventArgs e) { gridView1.AddNewRow(); } 具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写: private void gridView1_InitNewRow(object sender,DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e) { ColumnView View = sender as ColumnView; View.SetRowCellValue(e.RowHandle,View.Columns[0],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[0])); //复制最后一行的数据到新行
View.SetRowCellValue(e.RowHandle, View.Columns[1],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[1])); //复制最后一行的数据到新行
}
17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以)
18.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、AdvancedBandedView、LayoutView；共5种。 1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrolview 特效了 2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角 3）、Roll Angle 属性决定着 倾侧角度 4）、指定数据源，显示数据： //显示数据 private voidshowData(List<Employee > list) { DataTable dt= new DataTable("OneEmployee"); dt.Columns.Add("Caption", System.Type.GetType("System.String")); dt.Columns.Add("Department",System.Type.GetType("System.String")); dt.Columns.Add("PhotoName",System.Type.GetType("System.Byte[]"));
for(int i = 0; i < list.Count; i++) { DataRow dr = dt.NewRow(); dr["Caption"] = list[i].Name; dr["Department"] = list[i].Department; string imagePath = @"D:C#photos" + list[i].PhotoPath; dr["PhotoName"] = getImageByte(imagePath); dt.Rows.Add(dr); } gridControl1.DataSource = dt; }
//返回图片的字节流byte[] private byte[] getImageByte(stringimagePath) { FileStreamfiles = new FileStream(imagePath, FileMode.Open); byte[]imgByte = new byte [files.Length ]; files.Read(imgByte, 0, imgByte.Length); files.Close(); returnimgByte; }
19.检查数据的有效性 在gridview的ValidateRow事件中加入检查代码： #region 检查数据 private void gridView1_ValidateRow(object sender, ValidateRowEventArgse) { GridView view = sender as GridView; view.ClearColumnErrors();
if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") ==DBNull.Value) { e.Valid = false; view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期"); }
} #endregion 调用gridview.UpdateCurrentRow()方法执行检查
最常用的DevExpress Winform 4个代码片段：
一 、GridControl的删除操作
private void rILinkEditInfoDel_Click(object sender, EventArgs e) { if (XtraMessageBox.Show("请确定是否删除当前记录？", "警告",MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes) { DataRow row =gvInfos.GetDataRow(gvInfos.FocusedRowHandle); delByCode(row["Code"].ToString()); XtraMessageBox.Show("操作成功！"); } }
二、绑定非数据表中列
Hashtable ht = new Hashtable();
private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgse) { GridView View = sender as GridView; if (e.RowHandle >= 0) { object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]); if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value) { decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["Value"])); objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]); objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]); if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != "") { decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"])); decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"])); if (gridColumn2 > AverValue || AverValue > gridColumn1) { if (!ht.ContainsKey("pic")) ht.Add("pic", GetImage(1)); e.Value = ht["pic"]; } } } } }
/// <summary> /// 由资源文件获取图片 /// </summary> /// <param name="key"></param> /// <returns></returns> byte[] GetImage(int key) { Image img =DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif",key.ToString()), typeof(RiverInfos).Assembly); returnDevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img,ImageFormat.Gif); }
/// <summary> /// 动态根据条件设置行样式 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void gridView6_RowStyle(object sender,DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e) { GridView View = sender as GridView; if (e.RowHandle >= 0) { object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]); if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value) { decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"])); objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]); objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]); if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != "") { decimal gridColumn2 = Convert.ToDecimal(MinValue); decimal gridColumn1 = Convert.ToDecimal(MaxVlaue); if (gridColumn2 > AverValue || AverValue > gridColumn1) { e.Appearance.ForeColor = Color.Red; e.Appearance.BackColor = Color.LightGray; } } } } }
三、GridControl 中颜色选择控件
private void gvMapColor_CustomUnboundColumnData(object sender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e) { GridView view = sender as GridView; DataView dv = view.DataSource as DataView; if (e.IsGetData) { string strVal =dv[e.ListSourceRowIndex]["Color"].ToString(); if (strVal != "") { //e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal); e.Value = Common.HexToColor(strVal); } } else { //Color colorVal =DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString()); Color colorVal =(Color)e.Value; dv[e.ListSourceRowIndex]["Color"] =Common.RGB_HEX(colorVal.ToArgb()); } }
四、关于 GridControl 验证示例
/**//// <summary> /// 初始化GridView，绑定数据 /// </summary> /// <param name="parentId"></param> private void GridViewBindData(string parentId) { this.gridView1.Columns.Clear(); this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId); this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

RepositoryItemTextEdit textEditReg_Id = newRepositoryItemTextEdit(); textEditReg_Id.Mask.EditMask =parentId+"\d{2,3}"; textEditReg_Id.Mask.MaskType =DevExpress.XtraEditors.Mask.MaskType.Regular;
this.gridView1.Columns["reg_id"].ColumnEdit =textEditReg_Id;
this.gridView1.Columns["reg_desc"].ColumnEdit= new RepositoryItemMemoExEdit();
TreeListNode node =this.treelArea.FocusedNode.ParentNode; string fid =node==null?"0":node.GetValue("RegID").ToString().Trim(); DataSet ds =areaSetupActionHelper.getDsRegionByParentId(fid); RepositoryItemLookUpEdit lookUEParent_Id = newRepositoryItemLookUpEdit(); lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_id", 40, "区划编号")); lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_name", 40, "区划名称")); lookUEParent_Id.DataSource = ds.Tables[0].DefaultView; lookUEParent_Id.ValueMember = "reg_id"; lookUEParent_Id.DisplayMember = "reg_id"; this.gridView1.Columns["parent_id"].ColumnEdit =lookUEParent_Id; } /**//// <summary> /// gridView单元格验证的相关处理程序 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void gridView1_ValidatingEditor(objectsender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e) { if (e.Valid == false&this.gridView1.FocusedColumn.FieldName =="reg_id") { e.ErrorText = "区划编号不合法！ 应为父区划编号加2～3位数据组成！"; } if (this.gridView1.FocusedColumn.FieldName =="reg_name") { Regex reg=new Regex(@"[u4e00-u9fa5]{1,20}"); Match m=reg.Match(e.Value.ToString().Trim()); if (m.Length != e.Value.ToString().Trim().Length) { e.Valid = false; e.ErrorText = "区划名称应为汉字 长度为1至20"; } } }
private void gridView1_InvalidValueException(objectsender, InvalidValueExceptionEventArgs e) { if (MyDialog.Alert(" 您所填写的内容不符合规则 要放弃您刚才对此项所做的更改吗？", "您所编辑的内容不符合规则", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) ==DialogResult.Yes) { e.ExceptionMode = ExceptionMode.Ignore; } }
/**//// <summary> /// gridView行验证的相关处理程序 /// </summary> private void gridView1_ValidateRow(objectsender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e) { string regid = this.gridView1.GetRowCellValue(e.RowHandle,"reg_id").ToString().Trim(); string regName = this.gridView1.GetRowCellValue(e.RowHandle,"reg_name").ToString().Trim(); if ( regid.Length < 1) { e.Valid = false; this.gridView1.SetColumnError(this.gridView1.Columns["reg_id"],"请填写区划编号!",DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default); // e.ErrorText = "区划名称不能为空!"; } if (regName.Length < 1) { e.Valid = false; this.gridView1.SetColumnError(this.gridView1.Columns["reg_name"],"区划名称不能为空!",DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default); } }
private void gridView1_InvalidRowException(object sender,DevExpress.XtraGrid.Views.Base.InvalidRowExceptionEventArgs e) {
if (e.RowHandle >= 0) { if (this.gridView1.GetRowCellValue(e.RowHandle,this.gridView1.Columns["reg_id"]).ToString().Trim() == ""|| this.gridView1.GetRowCellValue(e.RowHandle,this.gridView1.Columns["reg_name"]).ToString().Trim() =="") { if (MyDialog.Alert(" 您所填写的内容不符合规则 要放弃您刚才对此项所做的更改吗？","您所编辑的内容不符合规则", MessageBoxButtons.YesNo,MessageBoxIcon.Warning) == DialogResult.Yes) { e.ExceptionMode = ExceptionMode.Ignore; } else { e.ExceptionMode = ExceptionMode.NoAction; } } } else { e.ExceptionMode = ExceptionMode.Ignore; } }
