白色间距datagrid视图 [英] White spacing datagrid view

问题描述

我有一个带有几行的datagridview。我想避免用户点击空白区域（行后空白区域）



或者至少我可以在用户点击空白区域时捕获，所以可能是一条消息显示。



请告知如何操作。



谢谢

Hi,
I have a datagridview with a few rows. I want to refrain user from clicking the white spaces (empty area after rows)

Or at least I could catch when user clicks the empty area, so a message could be displayed.

Please advise how to do it.

Thanks

推荐答案

如果您在行之后讨论网格内的空白区域，则将网格的AutoSizeColumnsMode属性设置为FILL。然后列将自动调整为gridview宽度。



如果你在谈论一个空单元格，那么 -

If you are talking about the empty area inside the grid after rows then set AutoSizeColumnsMode property of grid to FILL. then columns will be auto sized to gridview width.

If you are talking about an empty cell then -

Private Sub DataGridView1_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    Dim MyVal As String = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value.ToString
    If String.IsNullOrWhiteSpace(MyVal) Then
        MsgBox("You click on empty cell")
    End If
End Sub
