Provide an option for the RadComboBox to have as its popup a multi-column GridView together with a further option to search within that popup GridView.
Hi Yana, Thank you for your response. I suspected this scenario might be beyond RadComboBox since DevExpress chose to release a separate control (WPF and SL) called LookupEdit in addition to their ComboBox for this scenario. The lack of this functionality is preventing our moving to Telerik controls in a particularly large project. Might Telerik, similarly to DevExpress, release a separate control for this scenario? Whether the functionality comes in RadComboBox or another control doesn't matter so long as the scenario is properly supported. RadAutoCompleteBox whilst useful currently does not properly support this scenario. Kind Regards Gary
This is quite a complex scenario and is not part of the specification of the control. You could use RadAutoCompleteBox which provides the option to customize its filtering behavior, please check the following example in our XAML SDK Repository: https://github.com/telerik/xaml-sdk/tree/master/AutoCompleteBox/TwoPropertiesFilteringBehavior
