Aggragates Not Showing on Startup

[Randy]

When I start the application it doesn't show the aggrigates. If I create a group, it shows now only the group aggrigates, but also the footer ones appear. If I remove the group than the footer stays. If I refresh the page, they disappear. I have the code trimmed down to a very basic set. The dataset is an ObservableColleciton of my class. I did implement iNotify on it. I don't think it would be a class problem, because that shouldn't change with the grouping and ungrouping.

Hopefully you can shed some light on it for me. I can upload the entire silverlight project if needed.

Thanks
Randy

Hello Randy,

 

May you please share with us what version of RadGridView you are currently using? I believe that the best option is to send us a runnable project in a new support ticket which we can use for local testing and debugging. Thus we would be able to provide you with an appropriate solution for this use-case.

Greetings,
Vanya Pavlova
