textbox can't get focus after BusyIndicator.IsBusy=false
textbox can't receive focus right after change the ISBusy property. That's because of animation of Busyindication is still running,and it is impossible for the internal control to receive focus.
Telerik team offer the way to resolve this issue. The IsBusyIndicationVisible property is updated later than the IsBusy property,so the focus is correctly set to the inside element.
i will post it tomorrow.
