写在前面，Dev控件已经很久了，功能也很强大，截止到现在我编写文档出来的Dev的版本已经到了14.1了，看了Demo真的很强大，效果也很好，结合自己这一个月开发，分享一下自己研究过后的经验，不让大家走更多的弯路
- DevExpress安装顺序
- GridControl基本样式设置
- GridControl常用事件和描述
- GridControl右键菜单
- GridControl全选和反选
- GridControl添加小计功能
-
GridControl固定表头
1.安装从未如此简单
Dev的安装文件已经放大百度云中方便大家下载：DevExpress 12.2.7，下载后按照图片数字顺序依次安装，这就是Dev 12.2.7，你值得拥有。
if (bandedGridView1.GetFocusedDataRow() == null) return; //运单编号 var columnValue= bandedGridView1.GetFocusedRowCellValue("绑定列字段名称").ToString();注意事项：使用VS2012和2010搭配DevExpress 12.2.7这个版本一起开发是最好的，工具箱暂时无法导入VS2013
2.基本样式设置，你会吗？
面对第一次使用GridControl，
搞不懂GridControl下面为什么有一堆的GridView呢？后来想想，原来GridControl是一个大容器，下面有很多视图，那么就是操作视图，下面是我的一些常用样式设置。

bandedGridView1.IndicatorWidth = 40; //自增列宽度bandedGridView1.OptionsView.ColumnAutoWidth = false; //自动调整列宽，使所有列的宽度和视图的宽度匹配bandedGridView1.OptionsCustomization.AllowSort = false;//禁止用户对数据进行排序操作bandedGridView1.OptionsCustomization.AllowColumnResizing = false; //禁止各列头改变列宽bandedGridView1.VertScrollVisibility = ScrollVisibility.Auto; //显示垂直滚动条bandedGridView1.HorzScrollVisibility = ScrollVisibility.Auto; //显示水平滚动条bandedGridView1.OptionsMenu.EnableColumnMenu = false; //禁止列头上的菜单bandedGridView1.OptionsMenu.EnableFooterMenu = false; //禁止页脚上的菜单bandedGridView1.OptionsMenu.EnableGroupPanelMenu = false; //禁止分组面板上的菜单bandedGridView1.OptionsNavigation.UseTabKey = false; //不使用TAB/SHIFT+TAB移动焦点bandedGridView1.OptionsBehavior.Editable = false;//不允许编辑bandedGridView1.OptionsBehavior.ReadOnly = true;//只读 |
3.这些事件你会常用
CustomDrawRowIndicator：DGV显示自增行号
e.Appearance.TextOptions.HAlignment = HorzAlignment.Far;
if (e.Info.IsRowIndicator)
{
if (e.RowHandle >= 0)
{
e.Info.DisplayText = (e.RowHandle + 1).ToString(CultureInfo.InvariantCulture);
}
else if (e.RowHandle < 0 && e.RowHandle > -1000)
{
e.Info.Appearance.BackColor = Color.AntiqueWhite;
e.Info.DisplayText = "G" + e.RowHandle;
}
}
RowCellStyle：GridView隔行变色
bandedGridView1.Appearance.OddRow.BackColor = Color.White; // 设置奇数行颜色 // 默认也是白色 可以省略
bandedGridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面绑定 同时使用有效
bandedGridView1.Appearance.EvenRow.BackColor = Color.FromArgb(255, 250, 205); // 设置偶数行颜色
bandedGridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面绑定 同时使用有效
if (e.RowHandle == bandedGridView1.FocusedRowHandle)
{
e.Appearance.Font = new Font("宋体", 9, FontStyle.Bold);
}
FocusedRowChanged：选中行改变绑定行数据到对应控件中

if (bandedGridView1.GetFocusedDataRow() == null) return;//判断当前选中行是否为null //返回值 var columnValue= bandedGridView1.GetFocusedRowCellValue("绑定列字段名称").ToString(); |
4.添加右击菜单一个很常用的功能
添加ContextMenuStrip控件，然后自定义按钮，可以找一些16*16的小图标点缀一下，很不错
这样一个右键菜单就已经绑定成功
5.GridControl全选和反选
这是一个比较难的问题，这里我结合网上寻找的资料总结了一个实体类贴上源代码

using System.Drawing;
using System.Windows.Forms;
using DevExpress.XtraEditors.Repository;
namespace ZTO.WayBill.Utilities
{
/// <summary>
/// Dev GridControl 创建全选复选框

public class DevControlHelper
{
/// <summary>
/// 创建复选框
/// </summary>
/// <param name="e"></param>
/// <param name="chk"></param>
public static void DrawCheckBox(DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e, bool chk)
{
RepositoryItemCheckEdit repositoryCheck = e.Column.ColumnEdit as RepositoryItemCheckEdit;
if (repositoryCheck != null)
{
Graphics g = e.Graphics;
Rectangle r = e.Bounds;
DevExpress.XtraEditors.ViewInfo.CheckEditViewInfo info;
DevExpress.XtraEditors.Drawing.CheckEditPainter painter;
DevExpress.XtraEditors.Drawing.ControlGraphicsInfoArgs args;
info = repositoryCheck.CreateViewInfo() as DevExpress.XtraEditors.ViewInfo.CheckEditViewInfo;
painter = repositoryCheck.CreatePainter() as DevExpress.XtraEditors.Drawing.CheckEditPainter;
info.EditValue = chk;
info.Bounds = r;
info.CalcViewInfo(g);
args = new DevExpress.XtraEditors.Drawing.ControlGraphicsInfoArgs(info, new DevExpress.Utils.Drawing.GraphicsCache(g), r);
painter.Draw(args);
args.Cache.Dispose();
}
}
/// <summary>
/// 全选，反选
/// </summary>
/// <param name="gridView"></param>
/// <param name="fieldName"></param>
/// <param name="currentStatus"></param>
/// <returns></returns>
public static bool ClickGridCheckBox(DevExpress.XtraGrid.Views.Grid.GridView gridView, string fieldName, bool currentStatus)
{
bool result = false;
if (gridView != null)
{
gridView.ClearSorting();//禁止排序
gridView.PostEditor();
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.FieldName == fieldName)
{
for (int i = 0; i < gridView.RowCount; i++)
{
gridView.SetRowCellValue(i, fieldName, !currentStatus);
}
return true;
}
}
return result;
}
}
}
下面是使用步骤
窗体加载事件添加一些代码
private bool _mCheckStatus; //GridControl全选，作为全局变量，默认false
private void FrmInputBill_Load(object sender, EventArgs e)
{
bandedGridView1.OptionsBehavior.Editable = false;
bandedGridView1.OptionsBehavior.ReadOnly = true;
var col = new BandedGridColumn { FieldName = "Check", Visible = true, VisibleIndex = 0, ColumnEdit = new RepositoryItemCheckEdit() };
col.OptionsColumn.AllowEdit = true; //CheckBox可以编辑改变
gridBand1.Columns.Insert(0, col);
bandedGridView1.Click += bandedGridView1_Click;
bandedGridView1.CustomDrawColumnHeader += bandedGridView1_CustomDrawColumnHeader;
bandedGridView1.DataSourceChanged += bandedGridView1_DataSourceChanged;
//这里绑定数据源
}
#region GridControl支持全选事件
private void bandedGridView1_Click(object sender, EventArgs e)
{
if (DevControlHelper.ClickGridCheckBox(this.bandedGridView1, "Check", _mCheckStatus))
{
_mCheckStatus = !_mCheckStatus;
}
}
private void bandedGridView1_CustomDrawColumnHeader(object sender, ColumnHeaderCustomDrawEventArgs e)
{
if (e.Column != null && e.Column.FieldName == "Check")
{
e.Info.InnerElements.Clear();
e.Painter.DrawObject(e.Info);
DevControlHelper.DrawCheckBox(e, _mCheckStatus);
e.Handled = true;
}
}
private void bandedGridView1_DataSourceChanged(object sender, EventArgs e)
{
GridColumn column = this.bandedGridView1.Columns.ColumnByFieldName("Check");
if (column != null)
{
column.Width = 40;
column.OptionsColumn.ShowCaption = false;
column.ColumnEdit = new RepositoryItemCheckEdit();
}
}
#endregion
6.添加小计功能
第一步
第二步
加载完数据之后绑定
bandedGridView1.Columns["绑定字段列名"].Summary.Add(DevExpress.Data.SummaryItemType.Count, "BILL_CODE", "总计:{0}条"); //添加小计功能，在指定的列上添加一个统计对象
删除动作修改对应的小计信息，代码如下：
bandedGridView1.Columns["绑定字段列名"].Summary[0].DisplayFormat = string.Format("小计{0}条", bandedGridView1.RowCount);
7.固定表头
记录了一些GridControl的常用代码，分享给大家，如果有兴趣的可以到我的群里进行提问，不仅包括GridControl，其他的控件我也研究了，运用到项目中
将来的你一定会感激现在拼命的自己
