C1FlexGrid 是 .NET 平台中性能最佳的表格控件，常用于数据显示和数据编辑操作，今天主要讲解如何在C1FlexGrid 表格控件中增加自定义的编辑和删除列。
首先，我们加载 C1FlexGrid 的数据源，代码如下：
List<Item> list = new List<Item>();
list.Add(new Item() { ID = 1, Code = "A10001", Name = "产品A1", Description = "产品A1" });
list.Add(new Item() { ID = 2, Code = "A10002", Name = "产品A2", Description = "产品A2" });
list.Add(new Item() { ID = 3, Code = "A10003", Name = "产品A3", Description = "产品A3" });
list.Add(new Item() { ID = 4, Code = "A10004", Name = "产品A4", Description = "产品A4" });
list.Add(new Item() { ID = 5, Code = "A10005", Name = "产品A5", Description = "产品A5" });
c1FlexGrid1.DataSource = list;
然后，添加编辑列和删除列，并设置这两列中显示的图标，代码如下：
c1FlexGrid1.Cols.Add(2);
c1FlexGrid1.Cols[5].Width = 20;
c1FlexGrid1.Cols[5].AllowEditing = false;
c1FlexGrid1.Cols[6].Width = 20;
c1FlexGrid1.Cols[6].AllowEditing = false;
for (int row = 1; row < c1FlexGrid1.Rows.Count; row++)
{
c1FlexGrid1.SetCellImage(row, 5, Image.FromFile(@"Images\Edit.png"));
c1FlexGrid1.SetCellImage(row, 6, Image.FromFile(@"Images\Delete.png"));
}
最后在 C1Flexgrid 的 MouseClick 事件中判断当前点击的是那一列，并执行相应的操作，代码如下：
void c1FlexGrid1_MouseClick(object sender, MouseEventArgs e)
{
switch (c1FlexGrid1.Col)
{
case 5:
MessageBox.Show(string.Format("编辑产品：{0}",c1FlexGrid1[c1FlexGrid1.Row,2]));
break;
case 6:
MessageBox.Show(string.Format("删除产品：{0}", c1FlexGrid1[c1FlexGrid1.Row, 2]));
break;
default:
break;
}
}
