How to improve the GridComboBoxColumn dropdown item's opening time when it has a large number of items?

Platform: WPF |
Control: SfDataGrid |
.NET Framework: 4.5 |
Product Version:

You can overcome this problem by changing the ItemsPanel of ComboBox by editing its style. In the following code example VirtualizingStackPanel is loaded as ComboBox’s ItemsPanelTemplate to improve dropdown opening performance.
