Hello.
I don't know if it is what you want, but I know how to add checkbox columns on a datagridview. You could do it:
Dim dg1 As New DataGridView
Dim oColumn As New DataGridViewCheckBoxColumn
dg1.Columns.Add(oColumn)
dg1.Rows.Add(5)
For i As Integer = 0 To dg1.RowCount - 1
dg1.Item(0, i).Value = True
Next
Me.Controls.Add(dg1)
dg1.Dock = DockStyle.Fill
I hope it'll help you.
Att.
Giovani
