CheckBox in DataGridView

Submitted by admin on Saturday, October 24, 2009 - 22:23.

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:

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

THANK YOU DEAR

Thanks

Thank you :)

Thanks - I've been trying to figure this out for a long time

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

thx

Thank you
