Thank you for contacting us.
Could you please elaborate on the details of the issue you are experiencing? What Binding are you setting to true? Do you have the IsBusy property of RadBusyIndicator in mind? Are you using a custom Style for RadBusyIndicator?
Can you extract some code or a repro project and send it over to us so that we can investigate it locally? This would be the fastest way to find what is wrong. Thank you in advance.
We will be glad to assist you further.
