Hello,

We are using Telerik WPF controls, after updating to version 2018.2.620.45 RadWindow as main window is not showing.

In your samples "RadWindowAsMainWindow" project is working.

After only changing 3 Telerik dlls with new version dlls ("2018.2.620.45") main window doesn't show.

I couldn't attach the project because, attaching zip files is not allowed (And I think this is another problem).

Do we have to change something in code for new versions?

Thanks,

Burhan Eyimaya

Hi Burhan,

Thank you for your interest in our RadWindow control for WPF.

I have tested the RadWindow controls with the specified version and the RadWindow as Main Window is displayed as expected on my side. A common reason why the RadWindow is not shown is that the project referenced NoXAML binaries. When using NoXAML DLLs, the newly created user control will not receive automatically the Window style. You should add the following style after the merged dictionaries to fix this:
<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/Telerik.Windows.Themes.Material;component/Themes/System.Windows.xaml" />
        <ResourceDictionary Source="/Telerik.Windows.Themes.Material;component/Themes/Telerik.Windows.Controls.xaml" />
        <ResourceDictionary Source="/Telerik.Windows.Themes.Material;component/Themes/Telerik.Windows.Controls.Input.xaml" />
        <ResourceDictionary Source="/Telerik.Windows.Themes.Material;component/Themes/Telerik.Windows.Controls.Navigation.xaml" />
    </ResourceDictionary.MergedDictionaries>
    <Style TargetType="local:MainWindow" BasedOn="{StaticResource RadWindowStyle}"/>
</ResourceDictionary>

I am attaching the sample project which I used to test your scenario. Give this project a try and let me know if I am missing something specific.

Regarding the attaching a sample project. Our forum system allows adding only image files. If you want to send us a .zip file with the project that demonstrates the issue you can open a support ticket thread from your telerik.com account.
