UI Virtualization of DataFormComboBoxField

[HCT-CERT]

Hi,

I am trying to UI Virtualize a DataFormComboBoxField through styling, but could not find a way to do that.I copied the DataFormComboBoxField style in Blend but was not able to find the combo box on which to set the ItemsPanel to VirtualizingStackPanel.I am now doing through code and it works fine, but would like to move that to global style.

IEnumerable<DataFormComboBoxField> comboFields = MyRadForm.ChildrenOfType<DataFormComboBoxField>();

            foreach (DataFormComboBoxField comboField in comboFields)

            {

                

                  

                   ((RadComboBox)comboField.Content).ItemsPanel = Resources["VirtualizingItemsPanelTemplate
"] as ItemsPanelTemplate;

                 

            }

<ItemsPanelTemplate x:Key="VirtualizingItemsPanelTemplate">
            <VirtualizingStackPanel />
        </ItemsPanelTemplate>

Thanks

Hello Madani,

You do not need to find DataFormComboBoxField. You can create an implicit style targeting RadComboBox and it will be applied to its editing element (RadComboBox).
