I have the need for a cell to contain a XamTextEditor and a button beside the text editor to do some custom logic.  I tried this using a style that changed the CellValuePresenter below but it has a couple of problems.

 <Style
    TargetType="{x:Type igDP:CellValuePresenter}"
    x:Key="testField">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
                <StackPanel Orientation="Horizontal">
                    <igEditors:XamTextEditor
                        Width="{TemplateBinding Width}"
                        Text="{TemplateBinding Content}">
                    </igEditors:XamTextEditor>
                    <Button
                        Content="..."
                        Click="Button_Click"
                        Margin="2 0 0 0" />
                </StackPanel>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Problem 1: If the editor has no content then the editor width is really small.  I would like it to fill the cell.

Problem 2: The EditModeStarting/Started and EditModeEnding/Ended events don't fire for the text editor
