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);
}
}
2. 效果如下图

3. 合计行的单元格对象

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
