Hello,
I am currently trying to improve the UX of my application which uses RadGridViews.
At a high level, my current workflow is as follows: I my set RadBusyIndicator binding to true, fire a background worker to perform some work on a datatable (which is binded to the RadGridView) then set RadBusyIndicator binding to false on worker completed.
There are two problems I am encountering:
1) When the datatable has changed, the updating of the RadGridView blocks the UI thread, causing RadBusyIndicator to freeze. If the datatable is large enough, this can effectively freeze the application for quite some time. What would be the best way to show some kind of progress dialog for this?
2) The first time the RadGridView loads, the data_loaded event is fired. However when the datatable has changed and the RadGridView has updated, data_loaded event isnt fired. Is there an event I can monitor for this?

The BusyIndicator is useful only for background operations that does not affect UI, in other words you cannot use it to wait for UI to render. Being part of the WPF framework, the BusyIndicator is rendered on the main thread. If the UI is rendering and freezes the busy indicator will also freeze.
A possible approach which you can try is to open a new window on a separate main thread and load the busy indicator there. The general downside of trying to show some busy indication for the rendering in WPF is that the framework doesn't have a mechanism that tells you the rendering has finished.
Regarding the DataLoaded event, it depends on the action you want to trigger. Generally the Loaded and DataLoaded events are used but you can see all events in our overview.
