点击单元格显示图片用什么事件呢？

If radioButton1.Checked Then
            AddHandler C1FlexGrid1.MouseClick, AddressOf C1FlexGrid1_MouseClick
        Else
            RemoveHandler C1FlexGrid1.MouseClick, AddressOf C1FlexGrid1_MouseClick
        End If

radiobutton2 被激活时，有效果，radiobutton1被激活时，没有效果呢

失效呢

当radiobutton1.check = true 时，失效呢

你是想动态地为FlexGrid添加MouseClick事件，你可以试一试下面的代码：

1.     Private Sub radioButton1_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles radioButton1.CheckedChanged
   
2.         If radioButton1.Checked Then
   
3.             AddHandler C1FlexGrid1.MouseClick, AddressOf C1FlexGrid1_MouseClick
   
4.         Else
   
5.             RemoveHandler C1FlexGrid1.MouseClick, AddressOf C1FlexGrid1_MouseClick
   
6.         End If
   
7.     End Sub
   
8.     Private Sub C1FlexGrid1_MouseClick(sender As System.Object, e As System.Windows.Forms.MouseEventArgs)
   
9.         MessageBox.Show("click")
   
10.     End Sub

复制代码

假设
radiobutton1
radiobutton2
绘制了不同的表格
我并不希望在radiobutton2绘制的表格里有这样的功能

你想实现什么功能呢，如果在RadioButton1_CheckedChanged中调用C1FlexGrid1_MouseClick()，无法给C1FlexGrid1_MouseClick() 设置参数啊

我想把这个子程序放在radiobutton事件里面，该怎么调用呢？

Private Sub RadioButton1_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles RadioButton1.CheckedChanged
        If RadioButton1.Checked Then
            C1FlexGrid1_MouseClick()    这里报错        End If

    End Sub

哦，解决了

那如何实现，同行不同列的单元格显示不同的图片呢？

1.     Private Sub C1FlexGrid1_MouseClick(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles C1FlexGrid1.MouseClick
   
2.         If e.Button = Windows.Forms.MouseButtons.Left AndAlso C1FlexGrid1.Row = 2 Then
   
3.             If C1FlexGrid1.GetCellImage(C1FlexGrid1.Row, C1FlexGrid1.Col) Is Nothing Then
   
4.                 C1FlexGrid1.SetCellImage(2, C1FlexGrid1.Col, Image.FromFile("c1aspnet_gridview_32.png"))
   
5.             Else
   
6.                 C1FlexGrid1.SetCellImage(2, C1FlexGrid1.Col, Nothing)
   
7.             End If
   
8.         End If
   
9.     End Sub

我就想限定第2行，才有这个事件，
