网上有很多这样的例子
    主要都用的是ContextMenuStrip
    用法就是：先从工具栏里找到这个控件，拖动至winform
    DevExpress的GridControl可以在ContextMenu这个属性中选定Conntext

    在编辑项中添加按钮image.png
    主要设置toolstripmenuitem的名称
    在其Click事件中写入新建行和删除行的代码，主要通过判断点击位置的GridControl名称
    即这句最重要
    DevExpress.XtraGrid.GridControl gc=((DevExpress.XtraGrid.GridControl)((ContextMenuStrip)sender).SourceControl);

    1. private void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
    2.         {
    3.             DevExpress.XtraGrid.GridControl gc=((DevExpress.XtraGrid.GridControl)((ContextMenuStrip)sender).SourceControl);
    4.             //根据GridControl的名称判断执行的操作
    5.             //根据ContextMenuStripItem的name来判断       
    6.             if ((e.ClickedItem).Name == "menuExportData")//导入数据项
    7.             {
    8.                 XtraMessageBox.Show("menuExportData");
    9.             }
    10.             else if ((e.ClickedItem).Name == "menuAddRow")//
    11.             {
    12.                 switch(gc.Name)
    13.                 {
    14.                     case "tracks_gctrl":
