Hello,

We just noticed that the RadGridView comoBox box takes fairly longer to update when there are 1000+ plus items. We really need the loading process to be faster so that items are visible right away when clicking on the combo box. Is there a way to make item loading process faster?

Thanks,
Amit

you should use the VirtualizingStackpanel inside the Radcombobox. That's the only solution which i know so far if the combobox has a lot of items

However, if u use the VirtualizingStackpanel, you will LOSE the filtering property ANIMATion what i mean is that it still filter but won't discard the unfiltered one). That's really not a good filter. I hope Telerik will have a solution for it

<telerik:RadComboBox.ItemsPanel>
                                               <ItemsPanelTemplate>
                                                   <VirtualizingStackPanel />
                                               </ItemsPanelTemplate>
                                           </telerik:RadComboBox.ItemsPanel>
                                       </telerik:RadComboBox>
