very slowly displaying data

[Pavel]

Hi.

I set GridView with description below
Source collection is ObservableCollection and contains 20(!) items.
And this small collection is displaying almost the one second !
Why it so long ?
(standart wpf-grid displays the same collection in no time)

Please, could you give me some advice ?
(I have already read this http://www.telerik.com/help/silverlight/gridview-troubleshooting-performance.html)

Thank you !

<telerik:RadGridView
            x:Name="CaseListGrid"

            IsReadOnly="True"
            RowHeight="40"
            ColumnWidth="Auto"

Hi Pavel,

Thank you for the project.

I couldn't reproduce the slow initial loading on my end. One thing that can improve additionally the performance is to set fixed ColumnWidth instead of Auto.
