Grid performance with RadGridView with many rows as RowDetailsTemplate

[Andrii]

Hello!

My situation is like following.
I have a Grid with RowDetailsTemplate set to a RadGridView control. See the code of template below.

                <telerik:RadGridView x:Name="gridProgress" IsFilteringAllowed="False" ShowColumnHeaders="True" ShowGroupPanel="False"
                                    AutoGenerateColumns="True" AutoGeneratingColumn="gridProgress_AutoGeneratingColumn"
                                    AreRowDetailsFrozen="True" IsReadOnly="True" ScrollMode="Deferred"
                                    ItemsSource="{Binding Progress}"/>

The problem is that when the grid in Row Details has 1000+ rows performance of my application decreases drastically when details are open, while details are opening UI becomes irresponsible.
When the same information is shown in stand-alone RadGridView everything works fine, problem only appears when it is shown as Row Details.
Maybe my approach is wrong?

I'd appreciate any hints to what I could do avoid the problem.
Thanks in advance.

Hello,

 You can set height for the grid in row details to improve the performance.
