How to use in page?

[Alex]

How do I actually get this to work in a page? I've tried to insert it as I would a normal control from the toolbox menu but cannot find it and when I try to add it to the menu I still cannot find it?

Edit: Now on page in xaml but causes an exception when I try to set the isrunning to true:

When I check, busyidicator is returning a null reference?

Hi Alex,

Thanks for contacting us and for the provided snippets.

Normally, RadBusyIndicator is put over the contents you would like to disable when its IsRunning property is set to true. As with any other Silverlight control, you put it on a page, assign it a x:Name property and access it in the code-behind file. This should work just fine.

However, it seems that in your scenario something different happens and since I cannot exactly say what it is based on the snippets you are sending here, I would like to kindly ask you to prepare a sample project in which the issue is reproduced and send it to me for further investigation.

You will need to open a new support ticket in order to be able to upload files.

Thanks for your time.

Kind regards,
Deyan
