Hello Muhammad,

We were able to reproduce the issue. A member from Telerik UI for WPF and I inspected the behavior and we found that this outcome is based on how WPF works. At this point, the option that we recommend to try is to remove the System.Windows.xaml from the resource dictionary:

<ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/System.Windows.xaml" />

You can test the solution, then let us know if it works for you.

Hi i did try the above given solution but it still wont work for me. The style of button and text box is still changed due to the report theming. I try to move the resources to report viewer form class code behind but it threw an exception radloading component not found. Kindly give me working solution i am short on deadline thanks.

Hi Muhammad,

Fortunately, there is another workaround that we can suggest. Below are the required steps:

1. Add a folder Themes and insert the themes that you would like to use;

2. Remove them from the App.xml file;

3. Open Telerik.ReportViewer.Wpf.xaml file and add the rest of the themes before the declaration of the fonts:

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="/Themes/
    <ResourceDictionary Source="/Themes/
    <ResourceDictionary Source="/Themes/
    <ResourceDictionary Source="/Themes/
</ResourceDictionary.MergedDictionaries>

You can check the attached project which demonstrates the solution.

Note that this behavior is caused by a bug and we will do our best to fix it in some of the upcoming release.
