Display grid lines when disabled

[Etienne]

Hi,

I use Expression Dark theme with RadGridView and when the gridview is disabled, cells' border are hidden. I'm trying to display them anyway. I've been able to display vertical lines, but I can't find what to change to prevent hidding horizontal lines.

Thank you,

 Etienne

Hi Etienne,

In order to modify the default behavior, you should edit the default control template of GridViewCell. To learn how to style Telerik UI for WPF you can read the common topics on Setting a Theme (Using Implicit Styles) and Editing Control Templates. 

As to the specific question, one way would be to comment the ObjectAnimationUsingKeyFrames code for Disabled VisualState:

<VisualStateGroup x:Name="DisabledStates">
    <VisualState x:Name="Enabled"/>
    <VisualState x:Name="Disabled">
        <Storyboard>
            <DoubleAnimationUsingKeyFrames Storyboard.TargetName="PART_ContentPresenter" Storyboard.TargetProperty="Opacity">
<DiscreteDoubleKeyFrame KeyTime="0:0:0" Value="0.3"/>
   </DoubleAnimationUsingKeyFrames>
            <!--
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="Background_Disabled" Storyboard.TargetProperty="Visibility">
                <DiscreteObjectKeyFrame KeyTime="0">
                    <DiscreteObjectKeyFrame.Value>
                        <Visibility>Visible</Visibility>
                    </DiscreteObjectKeyFrame.Value>
                </DiscreteObjectKeyFrame>            </ObjectAnimationUsingKeyFrames>-->        </Storyboard>
    </VisualState>
</VisualStateGroup>

You can find attached a demo project. Please note, I also modified the GridView_GridLinesItemBorder color to be Yellow, for a better visual representation:

<!--Color modified-->
<SolidColorBrush x:Key="GridView_GridLinesItemBorder" Color="Yellow"/>
