    Hi,

    I saw this text on a Tips and Tricks page (http://www.telerik.com/help/silverlight/radgridview-performance-tips-tricks.html):

    Try not to place RadGridView in controls/panels which will measure it with infinity. For example, ScrollViewer, StackPanel and Grid with Row.Height=Auto or Column.Width=Auto will measure with infinity. If RadGridView is measured with infinity the virtualization turns off. Also setting RadGridView.ColumnWidth to a specific width (like 100) will increase both horizontal & vertical scrolling performance. Auto is a little bit slower and Star is the slowest (most noticeable when you have a lot of columns).

    What I normally do, is this:

    <Grid>
      <Grid.RowDefinitions>
                <RowDefinition Height="Auto " />
                <RowDefinition Height="*" />
              <RowDefinition Height="Auto " />
              </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>

     
    <Custom ToolBar Grid.Row="0" />
      <RadGridView Grid.Row="1"  />
     <StatusBar Grid.Row="2" />
    </Grid>

    But it seems that the tip-and-trick above tells me that this is a bad idea when it comes to performance.
    But I am bit at a loss on what to do, then. I want the GridView how have only the available space. If I cannot use the stackpanel or grid, then how? Dockpanel?

    I've googled a lot of answers to problems with infinity, but has been unable to spot a solution without Auto or Star.. Seems like everyone knows how to fix it without having it spelled out..  like me :-) ... Help will be appreciated!
