Dynamicaly created TemplateColumn with CheckBox

Hello,

I want to add TemplateColumn to DataGrid dynamicaly.
How to add, to this column checkbox (not bounded) and attach event, which argument has row values.


With ButtonColumn it's simple:

VB Code:

Dim CallBtn As New ButtonColumn
CallBtn.CommandName = "Deal"
CallBtn.ButtonType = ButtonColumnType.LinkButton
AddHandler RegDG.ItemCommand, AddressOf  RegDG_ItemCommand
 
Private Sub RegDG_ItemCommand(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
            If e.CommandName = "Deal" Then
                CallSub(CType(e.CommandSource, LinkButton).Text)
            End If
        End Sub

but what to do if I need checkbox, not button or linkbutton?

No ideas?
