I have a RadComboBox that is bound to a collection of about 1500 items. The ComboBox is searchable with filtering.
Everything was working as expected, except it was really slow to load.
I Added the VirtualizingStackPanel and this gave me the speed required for the app and text searching is working. However, the ComboBox is no longer filtering the results.
Here is my code:
I'm using the latest version of the control (Q2 2010 SP1).
Any help would be greatly appreciated.
