Default RadWindow style is not being overridden by custom style

[YBOT]

The style for my RadWindows is not being overriden from the default theme. I don't have the same issue with other telerik controls like RadButton, the style gets set fine for them. Why is this happening? How can I set a RadWindow style?

MyWindow.xaml

<telerik:RadWindow
    x:Class="MyWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Header="My Window"
    <Grid>
     // window content
            <telerik:RadButton
                Content="OK" />
            <telerik:RadButton
                Content="Cancel" />
        </StackPanel>
    </Grid>
</telerik:RadWindow>

 

 

My App.Xaml file contains MergedDictionaries

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/Telerik/RadButton.xaml" />
        <ResourceDictionary Source="pack://application:,,,/Telerik/RadWindow.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

 

Here are the individual xaml files

RadWindow.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

    <Style TargetType="{x:Type telerik:RadWindow}">
        <Setter Property="Background"
                Value="Green" />
    </Style>
</ResourceDictionary>

RadButton.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

    <Style TargetType="{x:Type telerik:RadButton}">
        <Setter Property="Background"
                Value="Blue" />

    </Style>
</ResourceDictionary>

Hello Toby,

Thank you for contacting us.

If you use RadWindow as a custom UserControl, you will need to apply a new style targeting the custom control and base it on the default RadWindowStyle. You should add the following implicit style in your App.xaml file under the merged dictionaries:

  <Style TargetType="local:MyWindow" BasedOn="{StaticResource RadWindowStyle}" /> 

The important part is to set the TargetType property to the type of the UserControl.

I hope this helps.
