System.Windows.ResourceDictionary Warning: 9 : Resource not found;

[Psyduck]

Hello.

 

When we debug or Run the application it works fine but in output window so many lines are coming with warning 

 

 

 

System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='AlternativeBrush'; ResourceKey.HashCode='18573990'; ResourceKey.Type='Telerik.Windows.Controls.FluentResourceKey'
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='AlternativeBrush'; ResourceKey.HashCode='18573990'; ResourceKey.Type='Telerik.Windows.Controls.FluentResourceKey'
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='BasicBrush'; ResourceKey.HashCode='1723761'; ResourceKey.Type='Telerik.Windows.Controls.FluentResourceKey'
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='MarkerBrush'; ResourceKey.HashCode='35310062'; ResourceKey.Type='Telerik.Windows.Controls.FluentResourceKey'

 

When an item is clicked on the parent grid view, the child grid view list is displayed.

Style is not used anywhere. This warning occurs at this time.

 

Implicit noxaml is in use and is version 2021.1.419.45. (Theme :Fluent)

 

 

Thanks.

Hello Kim,

Can you share the XAML showing your RadGridView setup?

[Psyduck]

Plz Check the sources.

In addition to this, System.Windows.ResourceDictionary Warnin is displayed in other outputs.

System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='ActiveTabBackgroundBrush'

Start Occurs when my dll is loaded when the external program is executed and the button in the external program is pressed.

 

 

Thanks.

Hello KIM,

I've tested the setup in a clean WPF project, but I couldn't reproduce any errors. You can check the attached project and let me know if I am missing anything.

I also checked the source you sent, and I also checked the new project I created, but there is no error here.
When checking my original source, an error occurred when the GridView Item was changed.
With a new project I can't catch it. I just try to use Doesn't it matter?

[Psyduck]

Hello.

For this problem, I did not set any styles, properties, etc., but I confirmed that an error appeared.

I am using an external application program and its API together.
Here, it was confirmed that this warning appeared when telerik assembly was performed together.

This external application program API also handles controllers such as ComboBox. I guess there is a conflict here.
As shown in the source below, when I execute the external program without taking any action and only assembly, a warning is output.

System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='ActiveTabBackgroundBrush'
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='ClientAreaBackgroundBrush'

 

Is there any way to avoid it?

Thanks.

[Martin Ivanov]

I will guess that the way the Telerik assemblies are loaded is causing some timing issues with the resources loading so the reported warnings are appearing. However, without be able to re-create this behavior I cannot tell why this happens and if there is a way to resolve it. Anyway, as I understand the Telerik components are working fine after the application is loaded, so if this is the case it sounds safe to ignore the warnings since they seem related to the loading process. 

[Psyduck]

Thank you. Finally. The event is fired when the text box loses focus.
Is there anything that the FluentResourceKey is associated with a 'AlternativeBrush'?

[Martin Ivanov]

The AlternativeBrush is simply a key used to access a Brush object through the  FluentResourceExtension class. This dynamic markup extension is used all over the styles and templates of the Telerik's Rad controls. You can see how the extension is used in the Fluent theme article.

[Psyduck]

In "{telerik1:FluentResource ResourceKey=AlternativeBrush}", I changed everything to the static value "#FFF2F2F2" and tested it. About 140 were changed and no warning was output. If so, is there a way to change it all? Telerik Xaml has been modified a lot, but this causes a situation where you need to change it again when you update the version.

[Martin Ivanov]

Do you mean you've changed it in the .xaml file with the Telerik styles and templates (like Telerik.Windows.Controls.GridView.xaml)? As you noted, modifying the default styles of Telerik controls come with the price of having extra work when upgrading to a newer version. Anyway, we cannot replace the FluentResource extension usage with a static value on our side, because this way we will loose the color variations ability of the theme.
