Contents in a RadPane

[NickZ]

Hello,  I have an issue with contents inside a radpane. 

Code 1

<telerikDocking:RadPane x:Name="Pane01" Header="ISHTA Committed">
    <telerikDocking:RadPane.Content>
        <StackPanel x:Name="MainLayout">
            <StackPanel x:Name="TopFilter" Orientation="Horizontal" Height="45" Background="Ivory" VerticalAlignment="Center">
                <TextBlock x:Name="AreaLabel" Text="Area" Canvas.Top="20"/>
                <telerikInput:RadComboBox x:Name="PeriodList" Width="75" Height="22" />
                <Button x:Name="FilterClick" Height="22" Width="75" Click="FilterClick_Click" Content="Filter" />
            </StackPanel>
            <StackPanel x:Name="GridArea">
                <data:RadGridView x:Name="ViewCommitted" AutoGenerateColumns="False" />
            </StackPanel>
        </StackPanel>
    </telerikDocking:RadPane.Content>
</telerikDocking:RadPane>

Code 2

<telerikDocking:RadPane x:Name="Pane01" Header="ISHTA Committed">
    <telerikDocking:RadPane.Content>
        <data:RadGridView x:Name="ViewCommitted" AutoGenerateColumns="False" />
    </telerikDocking:RadPane.Content>
</telerikDocking:RadPane>

Both are pretty much same, except Code 1 has some controls (combox, botton) at the top part of the panel separated by stackpanel.  Gridview will obtain data from DB through a webservice.  The problem is Code 1 ran extremely slow.  It seems that it is stackpanel related. In Code 2, there is no stackpanel and it runs pretty normal.  I really want to add the top part on this panel.  Can anyone help me on this?  Are there any other ways to handle this situation? 

Thanks a lot,
Nick

Hi NickZ,

The problem comes from the StackPanel. The issue is that the StackPanel as a Layout control is arranging its children using infinite width and height values. This is causing a problem with the virtualization mechanism in RadGridView. I am suggestion using a Grid instead of StackPanel.

All the best,
