Slow performance on GridView

[GOURVEZ JJ]

Hello,

I use 2 RadGridView (like First look example)
But I want display dynamically datagridviewDataColumns in the second RadGridView.
I use RowLoaded event to display column, but when I clicked on GridViewToggleRowDetailsColumn, is slow (3 minutes to 200 rows in my second GridView)

Can you help me ?

This is my code :

<telerik:RadGridView x:Name="RadGridView1" ScrollMode="Deferred" Drop="dropGridView1" AllowDrop="True" Margin="1,87,2,0"  RowIndicatorVisibility="Collapsed" IsReadOnly="True" RowHeight="30" AutoGenerateColumns="False" CanUserFreezeColumns="False"  ShowGroupPanel="False" BorderBrush="Beige"  SelectionChanged="cliRadGridView" Foreground="Black" GroupPanelForeground="#FFC79FDA" Style="{StaticResource RadGridViewStyle1}" Visibility="Collapsed">
                               <telerik:RadGridView.Columns>
                                   <telerik:GridViewToggleRowDetailsColumn HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}"/>

                                   <telerik:GridViewImageColumn Header="" DataMemberBinding="{Binding type}" ImageHeight="35" ImageWidth="35" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}"></telerik:GridViewImageColumn>


                               </telerik:RadGridView.Columns>
