You can use triggers to set different controls whe the CellValuePresenter is active.

Here is an example, 

<Style x:Key="MyStyle" TargetType="{x:Type igDP:CellValuePresenter}">
        <Style.Triggers>
            <Trigger Property="IsActive" Value="True">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
                            <TextBox
                                Text="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Value}"
                                HorizontalAlignment="Stretch"                              
                                VerticalAlignment="Center"
                                TextAlignment="Right"
                                Foreground="#FF151C55"
                                Margin="0,0,0,4"
                                Name="textBlock"/>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>
            <Trigger Property="IsActive" Value="False">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
                            <TextBlock
                                Text="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Value}"
                                HorizontalAlignment="Right"
                                VerticalAlignment="Center"
                                TextAlignment="Right"
                                Foreground="#FF151C55"
                                Margin="0,0,0,4"
                                Name="textBlock"/>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>   
        </Style.Triggers>
    </Style>

For the moment I don't know how to show the TextBox focused. 

Joe, did you see my previous post? Once I apply my link style to the CellValuePresenter, then the edit style must be overridden as well. When I double-click I want it to go back to the default behavior of using a xamTextEditor.

Thanks,Rod

Cool. Thanks. One more question. Now that I have overridden the CellValuePresenter style, how can get the default style back that allows me to edit again? When I double click on the cell, the style retains the textblock style instead of the default xamTextEditor.

Thanks,

Rod
