Style background of Cell in EditMode in RadGridView

Question

I want to style a cell in a RadGridView so whenever the cell turns into edit mode the backgroundcolor is e.g. yellow.

<telerik:RadGridView x:Name="Name" SelectionUnit="Cell">
  <telerik:RadGridView.Resources>
       <Style  TargetType="telerik:GridViewCell">
                <Style.Triggers>
                    <Trigger Property="IsInEditMode" Value="True">
                        <Setter Property="Background" Value="Yellow"/>
                    </Trigger>
                </Style.Triggers>
       </Style>
  </telerik:RadGridView.Resources>
</telerik:RadGridView>

This doesn't do anything.

Answer 1

As mentioned in the comments, the GridViewCell, when editable, displays a TextBox that consumes the entire space the GridViewCell has available; so setting the background of the GridViewCell does nothing, because you can't see the background of the GridViewCell. The solution is to change the background of the control that is displayed while the GridViewCell is editable, thus we need to change the Background of the TextBox.

In the RadGridView do the following:

<telerik:RadGridView.Resources>
        <Style TargetType="{x:Type TextBox}">
            <Setter Property="Background" Value="LightYellow"/>
        </Style>
</telerik:RadGridView.Resources>

It changes the background color of each selected-to-edit Cell to LightYellow.
