RadDocking - Stretch First RadSplitContainer & Auto Size 2nd RadSplitContainer

[Palani]

 I placed two RadSplitContainer inside RadDocking.

Is it possible to stretch frst RadSplitContainer and fix second RadSplitContainer width to auto.

You can check the below attachment for my requirement.

Code:

<telerik:RadDocking BorderThickness="0" Grid.Row="1" HasDocumentHost="False">
                        <telerik:RadSplitContainer x:Name="ContantContainer" HorizontalAlignment="Stretch">
                            <telerik:RadPaneGroup IsContentPreserved="True">
                                <telerik:RadPane x:Name="contentPane" CanUserClose="False" CanUserPin="False" CanFloat="False" PaneHeaderVisibility="Visible" Header="Pane1">
                                    <ContentPresenter Content="{TemplateBinding Content}" />
                                </telerik:RadPane>
                            </telerik:RadPaneGroup>
                        </telerik:RadSplitContainer>
                        <telerik:RadSplitContainer x:Name="editContainer" Width="Auto" HorizontalAlignment="Right">
                            <telerik:RadPaneGroup IsContentPreserved="True">
                                <telerik:RadPane x:Name="editPane" CanUserClose="False" CanUserPin="False" CanFloat="False" PaneHeaderVisibility="Visible" Header="Pane2">
                                    <ContentPresenter Content="{TemplateBinding Abstract}" />
                                </telerik:RadPane>
                            </telerik:RadPaneGroup>
                        </telerik:RadSplitContainer>
