Hi @rathapon,
I’m afraid that I don’t understand your question. Check our forum FAQ for more info on how to improve your question.
I'm unable to provide more info by just looking at your screenshots. Please debug your application to check what's null. If you have Radzen subscription you can send us an example application demonstrating the exception at info@radzen.com.
I can solve it.It's error becuase having null value in TemplaName List.
