Question

我在vb.net上有代码，只要单击一个单元格就会检查radiobutton3。但是当点击列标题或行标题时它也有效。如何使columheader和rowheader点击这段代码无法使用？

Cursor pointer

Answer 1

Private Sub MyDataGridView1_MouseDown(sender As Object, e As MouseEventArgs) Handles MyDataGridView1.MouseDown
    Dim ht As DataGridView.HitTestInfo
    ht = Me.MyDataGridView1.HitTest(e.X, e.Y)
    If ht.Type = DataGridViewHitTestType.Cell Then
        RadioButton3.Checked = True
        cont()
    End If
End Sub

Answer 2

e.RowIndex = -1表示行标题。 e.ColumnIndex = -1表示列标题。

您可以查看以下内容：

Private Sub shipmentDetailsDataGridView_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs)

    RadioButton3.Checked = e.ColumnIndex >= 0 AndAlso e.RowIndex >= 0

End Sub

Row和ColumnHeader，CellMouseClick事件vb.net
