    Hello,

    I was wondering if the solution offered by another user worked well for you.

    Another alternate solution would be to interate through all the relevant fields in the DataTable itself and modify the field there. Since the XamDataGrid is coupled to the DataTable, the UI would update dynamically.

    Thank you,

    Create a LabelPresenter and associate it with Field where you want checkbox to appear in teh header. And then define an event in code behind for label checkbox. Hope it helps

        <Window.Resources>
            <Style TargetType="{x:Type igDP:LabelPresenter}" x:Key="labelPresenterStyle1">
                <Setter Property="Visibility" Value="Visible" />
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type igDP:LabelPresenter}">
                            <StackPanel Orientation="Vertical">
