DataGridViewCheckBoxColumn, allow only one check in entire column

Question

Hi,

I have a DataGridViewCheckBoxColumn and I am trying not to allow more than one checked boxes in the column. So after one is checked, when user tries to check another one, i want to prevent that and not have more than one checked box in entire column.

Please help.

What you are describing is usually done using Radio Buttons except Radio Buttons also don't work like that for DataGridViews. There is an article in this web site however that shows how to do it.

Try this if worked then mark as accepted Private CheckColIndex As Integer = 0 Private Sub DataGridView1_CellValueChanged( ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged 'Check the column index and if the check box is checked. If e.ColumnIndex = CheckColIndex Then Dim isChecked As Boolean = CType ( Me .DataGridView1(e.ColumnIndex, e.RowIndex).Value, Boolean ) If isChecked Then 'If check box is checked, uncheck all the rows, the current row would be checked later. For Each row As DataGridViewRow In Me .DataGridView1.Rows row.Cells(e.ColumnIndex).Value = False Next End If End If End Sub
