Removing RadPanelBar highlighting in wpf

[Sayali]

I am facing issue in removing the highlighting effect(yellow color on mouse hover) of RadPaneBar in wpf application.
How to remove mouse hover effect from RadPanebar or any specific styles to be applied to remove highlighting.
Let me know.

Hello Sayali,

You can apply a custom theme to any of the controls. For more information you can follow the link below:

http://www.telerik.com/help/wpf/common-styling-appearance-edit-control-templates-blend.html

Please find attached an example.

If you have further questions please do not hesitate to ask us.
I hope this will help you.

Kind regards,

I followed the link referenced in this thread to investigate styling of the RadPanelBar control.
However, it does not work if you add "content" into a RadPanelBarItem.  e.g. If I add a simple <TextBlock> as content to one of the items, it still gets highlighted in yellow etc.

My modified MainWindow.xaml of the referenced sample is below.  You can see that I have added a <TextBlock> to "RadPanelBarItem1.2", which still gets styled in yellow.

How can I change the style of this element?

Thanks and regards
Craig Littlewood

Hi Craig,

The issue is caused by the fact that the RadPanelBarItemStyle1 custom style isn't applied on the RadPanelBarItem wrapping the TextBlock. In order to apply the RadPanelBarItemStyle1 style to all RadPanelBarItems you can make it implicit (remove its x:Key setting) or you can set the RadPanelBarItem1.2 ItemContainerStyle property so that it can apply your custom style to all children RadPanelBarItems:

<telerik:RadPanelBar HorizontalAlignment="Left" VerticalAlignment="Top" >
    <telerik:RadPanelBarItem Header="RadPanelBarItem1"
               IsExpanded="True"
               Style="{DynamicResource RadPanelBarItemStyle1}">
        <telerik:RadPanelBarItem Header="RadPanelBarItem1.1"
              Style="{DynamicResource RadPanelBarItemStyle1}"/>
        <telerik:RadPanelBarItem Header="RadPanelBarItem1.2"
              Style="{DynamicResource RadPanelBarItemStyle1}"
     ItemContainerStyle="{DynamicResource RadPanelBarItemStyle1}">
            <TextBlock Text="RadPanelBarItem1.2 TextBlock content"/>
        </telerik:RadPanelBarItem>
    </telerik:RadPanelBarItem>
    ...
</telerik:RadPanelBar>

I attached a sample solution based on your code snippet where I made the style implicit so that it can dynamically be applied to all RadPanelBarItems in the Window. I hope it helps.

Hello,
I am testing the rad controls for wpf.
Is there any way to do this without changing the style of the header?
I am interested in the header matches the selected template.

Thanks and sorry for my english.

I've seen that this example is useful in my case.
Thanks!
