The IsBusy property of my RadGridView is Bound to the IsChecked property of a checkbox, so if the checkbox is checked the grid shows the loading animation, if you uncheck it the grid shows the data. The problem is that, it only works once. So if you check the chkbx loading is displayed, uncheck and data is shown. Try the second time, third, forth, etc and the loading animation does not appear anymore.
Any ideas how to make it work every time I check the checkbox?
