SqlResourceType is Null on SqlResource about xaml-sdk

[drkhodakarami]

another issue with the same project, after the above failure, I tried to add resource types and resources in xml, so far good. But when I add grouping, and now I try to add a new appointment under a group, I get an error, here is the xml code:

<telerik:RadScheduleView.ResourceTypesSource> <telerik:ResourceTypeCollection> <telerik:ResourceType Name ="Service" DisplayName="Service" Brush="Coral" AllowMultipleSelection="True"> <telerik:Resource ResourceName="SkinCare" DisplayName="SkinCare" ResourceType="Service"/> <telerik:Resource ResourceName="Injection" DisplayName="Injection" ResourceType="Service"/> <telerik:Resource ResourceName="Visit" DisplayName="Visit" ResourceType="Service"/> </telerik:ResourceType> </telerik:ResourceTypeCollection> </telerik:RadScheduleView.ResourceTypesSource> <telerik:RadScheduleView.GroupDescriptionsSource> <telerik:GroupDescriptionCollection> <telerik:ResourceGroupDescription ResourceType="Service" ShowNullGroup="True"/> </telerik:GroupDescriptionCollection> </telerik:RadScheduleView.GroupDescriptionsSource>

and here is the error I get :
System.ArgumentException: 'The value "Injection" is not of type "DatabaseEntityFramework.SqlResource" and cannot be used in this generic collection. Parameter name: value'

and finally the call stack :

Hello,

I will proceed with closing this issue as the described error occurs after modifications to the mentioned RadScheduleView SDK example.

We recommend directing queries related to modifications of the examples in this repository to the UI for WPF forum or in a new support ticket.

Thank you in advance for your understanding
