Hello,

I would like that the users would be able to add filters while the grid loads asynchronously (loads a lot of data for ~10 seconds). Any ideas on how to make this possible as while the grid loads the filter-combobox is empty.

Hi,

In order to populate your distinct values asynchronously, you will have to assign e.ItemsSource first to some ObservableCollection before the method returns and then you can populate this observable collection asyncrhonously.
For example, you can create an empty ObservableCollection in the method and assign it to e.ItemsSource before doing anything else. Then in your async callback you can fill this exact same collection with the data. 

I have attached a demo solution which I hope you can use in your case.
