DevExpress13.2.9 控件使用经验总结

一.换肤功能

　　1. 添加 DevExpress.OfficeSkins 和 DevExpress.BonusSkins 两个引用

　　2. 皮肤注册

DevExpress.UserSkins.BonusSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();

　　3. 加载皮肤列表，调用 SkinTools.LoadSkinList 函数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using psi.Common;
using psi.Interfaces;
using DevExpress.Skins;
using DevExpress.LookAndFeel;

/************************************************************************* 
 * 程序说明: 设置皮肤工具
 **************************************************************************/
namespace psi.Library
{
    /// <summary>
    /// 设置皮肤工具
    /// </summary>
    public class SkinTools
    {
        private static ToolStripMenuItem _CurrentSkinList = null;

        /// <summary>
        /// 加载皮肤列表
        /// </summary>
        public static void LoadSkinList(ToolStripMenuItem owner)
        {
            _CurrentSkinList = owner;

            int skinCount = DevExpress.Skins.SkinManager.Default.Skins.Count;
            ToolStripItem[] itemArr = new ToolStripItem[skinCount];
            int index = 0;
            foreach (DevExpress.Skins.SkinContainer skin in DevExpress.Skins.SkinManager.Default.Skins)
            {
                ToolStripMenuItem item = new ToolStripMenuItem();
                item.Text = skin.SkinName;
                item.Name = skin.SkinName;
                item.Checked = skin.SkinName == SystemConfig.CurrentConfig.SkinName;
                item.Click += new System.EventHandler(OnSetSkinClick);
                itemArr[index] = item;
                ++index;
            }

            owner.DropDownItems.AddRange(itemArr);
        }

        /// <summary>
        /// 设置皮肤
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private static void OnSetSkinClick(object sender, EventArgs e)
        {
            ToolStripMenuItem clickItem = sender as ToolStripMenuItem;
            SetSkin(clickItem.Name);

            if (_CurrentSkinList != null)
            {
                foreach (ToolStripMenuItem item in _CurrentSkinList.DropDownItems)
                {
                    item.Checked = false;
                }
            }

            clickItem.Checked = true;
        }

        public static void SetSkin(string skinName)
        {
            //设置所有窗体的皮肤
            for (int i = 0; i < Application.OpenForms.Count - 1; i++)
            {
                Form form = Application.OpenForms[i];

                if (form is IFormBase) (form as IFormBase).SetSkin(skinName);
            }
        }
    }
}

　　4. 效果如下图

二. Grid 显示行号以及设置行号列名称

　　1. 添加 GridView 方法 CustomDrawRowIndicator

/// <summary>
/// 显示行号和设置行号列头部的字符
/// </summary>
private void gvSummary_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
    if (e.Info.Kind == DevExpress.Utils.Drawing.IndicatorKind.Header)
    {
        e.Info.DisplayText = "行号";
    }
    e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
    if (e.Info.IsRowIndicator && e.RowHandle >= 0)
    {
        e.Info.DisplayText = Convert.ToString(e.RowHandle + 1);
    }
}

三. Grid 下添加固定合计行

　　1. 继承 GridView ，自定义表格 GridViewSummary，改变Grid父级控制器

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Diagnostics;
using System.Linq;
using System.Text;
using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Columns;
using System.Windows.Forms;
using DevExpress.Skins;
using DevExpress.LookAndFeel;
using System.Drawing;
using DevExpress.XtraGrid;
using System.Collections;

　　4. 使用自定义表格 GridViewSummary，效果如下

四. Grid 自定义绘制操作列头

　　1. 创建  修改列(operate_modify)、删除列(operate_del)

　　2. 添加 GridView 方法  CustomDrawColumnHeader，绘制表头

/// <summary>
/// 自定义绘制操作列表头
/// </summary>
private void gvDetail_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e)
{
    if(e.Column != null)
    {
        if (e.Column == operate_modify)
        {
            e.Info.InnerElements.Clear();
            e.Painter.DrawObject(e.Info);
            e.Handled = true;

            int delColumnWidth = operate_del.VisibleWidth;
            e.Graphics.FillRectangle(new SolidBrush(e.Info.Appearance.BackColor), new Rectangle(e.Bounds.X - delColumnWidth + 1, e.Bounds.Y + 1, e.Bounds.Width + delColumnWidth - 2, e.Bounds.Height - 2));
            e.Graphics.DrawString("操作", new Font("宋体", 9f), new SolidBrush(e.Info.Appearance.ForeColor), new Rectangle((e.Bounds.X - delColumnWidth) + (e.Bounds.Width + delColumnWidth) / 2 - 15, e.Bounds.Y + 8, 30, 15));
        }        
    }
}

　　3. 效果如下

五. Grid 绘制复选框和全选框

　　1. 创建  复选框列(check)

　　2. 添加 GridView 方法 CustomDrawCell，绘制复选框

/// <summary>
/// 自定义绘制删除、修改单元格
/// </summary>
private void gvDetail_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
{
    GridView currentView = sender as GridView;
    if (e.Column == check)
    {
        ControlPaint.DrawCheckBox(e.Graphics, new Rectangle(e.Bounds.X + e.Bounds.Width / 2 - 8, e.Bounds.Y + 3, 16, 16), checkBoxState[e.RowHandle]);
    }        
}

　　3. 添加 GridView 方法 CustomDrawColumnHeader，绘制全选框

/// <summary>
/// 自定义绘制操作列表头
/// </summary>
private void gvDetail_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e)
{
    if(e.Column != null)
    {
        if (e.Column == check)
        {
            e.Info.InnerElements.Clear();
            e.Painter.DrawObject(e.Info);
            e.Handled = true;

            ControlPaint.DrawCheckBox(e.Graphics, new Rectangle(e.Bounds.X + e.Bounds.Width / 2 - 8, e.Bounds.Y + 6, 16, 16), allSelectState);
        }
    }
}

　　4. 添加 GridView 方法 Click ，判断全选框是否被点击，若有则重绘所有复选框

/// <summary>
/// 判断Grid全选框是否被单击
/// </summary>
/// <param name="gridView"></param>
/// <param name="name"></param>
/// <returns></returns>
public bool ClickGridCheckBox(DevExpress.XtraGrid.Views.Grid.GridView gridView, string name)
{
    bool result = false;
    if (gridView != null)
    {
        DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo info;
        Point pt = gridView.GridControl.PointToClient(Control.MousePosition);
        info = gridView.CalcHitInfo(pt);
        if (info.InColumn && info.Column != null && info.Column.Name == name)
        {
            return true;
        }
    }
    return result;
} 


private void gvDetail_Click(object sender, EventArgs e)
{
    if (ClickGridCheckBox(this.gvDetail, "check"))
    {
        allSelectState = allSelectState == ButtonState.Checked ? ButtonState.Normal : ButtonState.Checked;
        selCount = allSelectState == ButtonState.Checked?0:checkBoxState.Count;
        
        for (int i = 0; i < checkBoxState.Count; i++)
        {
            SetCheckBoxState(i, allSelectState);
        }
    }
}

/// <summary>
/// 重新绘制复选框
/// </summary>
/// <param name="rowHandle"></param>
/// <param name="state"></param>
private void SetCheckBoxState(int rowHandle, ButtonState state)
{
    checkBoxState[rowHandle] = state;
    //获取点击单元格左上角的坐标
    GridViewInfo info = gvDetail.GetViewInfo() as GridViewInfo;
    GridCellInfo cellInfo = info.GetGridCellInfo(rowHandle, check);

    ControlPaint.DrawCheckBox(gcDetail.CreateGraphics(), new Rectangle(cellInfo.Bounds.X + cellInfo.Bounds.Width / 2 - 8, cellInfo.Bounds.Y + 3, 16, 16), state);

}

　　5. 效果如下
