Performance issue in grid view control

[SUSHAMA]

Hi,

I have 8 RadGridViews in my wpf application. I have used some properties of the RadGridView in the below code snippet. Each RadGridView is added inside an Expander.

When I select an item in a tree view, I change the Datacontext of the Expander. But the rendering of the control  takes too much of tne time. How do i improve the rendering performance of my RadGridViews?  Am i missing anything? Can anyone help.

<Telerik:RadGridView CanUserFreezeColumns="False"

                                                                     RowIndicatorVisibility="Collapsed"

                                                                     RowDetailsVisibilityMode="{Binding ElementName=root,Path=CanEdit.IsEnabled,IsAsync=True,Converter={StaticResource rowdetailsvisibilityconverter}}"

                                                                     RowDetailsTemplate="{StaticResource propertyEditTemplate}"

                                                                     ItemsSource="{Binding Properties}"

                                                                     AutoGenerateColumns="False"

                                                    </Telerik:RadGridView.Columns>

Hello Sushama,

Generally, an expander measures its children with infinity, which breaks the whole virtualization process. Please check out this article for a reference.
