In this program I will teach you on how to validate a CheckBox control before the value are change inside a DataGridView.

I have tested all the events and only DataGridView CellMouseDown can do this. The point here is to validate first if the user really want to change the value of a CheckBox to true. If not then the value of a CheckBox will revert to false.

The important code in this program is:

  1.     Private Sub DataGridView1_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseDown
  2.         If e.ColumnIndex = 5 Then
  3.             If DataGridView1(5, e.RowIndex).Value() = False Then
  4.                 If MessageBox.Show("Are you sure you want to discontinue this product?", "CheckBox", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then
  5.                     DataGridView1(5, e.RowIndex).Value = True
  6.                 End If
  7.             End If
  8.         End If
  9.     End Sub

Your code got me on the right track, but didn't work quite as I wanted, so I tried dgv_MouseUp - works perfectly. I have a dgv with the 3rd column a checkbox column. I put a label on my form. When I click a checkbox the value on the label corresponds with the cell value.

Private Sub dgv_CellMouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles dgvBlockModel.CellMouseUp
If e.ColumnIndex = 2 Then

If dgv.CurrentCell.Value = False Then
dgv.CurrentCell.Value = True
Else
dgv.CurrentCell.Value = False
End If

lblValue.Text = (dgv(2, e.RowIndex).Value.ToString)

End If
End Sub
