Adding RadPane to RadPaneGroup Programatically

[Ryan]

Hi Everyone,

I need to be able to add a RadPane control to a RadPaneGroup Programatically. I am using the following code to add the new RadPane to a RadPaneGroup that is declared in XAML.

PnlVehicleStatus = new RadPane
{
   CanFloat = true,
   CanDockInDocumentHost = false,
   CanUserPin = true,
   Title = "Vehicle Status",
   Header = "Vehicle Status",
   CanUserClose = true,
   IsPinned = true,
   Name = "PnlVehicleStatus",
   Tag = "Test"
};
PnlVehicleStatus.SetValue(RadDocking.SerializationTagProperty,"PnlVehicleStatus");
PnlVehicleStatus.Content = new GeoHostVehicleStatus();
AddWindowToToggle(PnlVehicleStatus, (string)PnlVehicleStatus.Header);
RSCDockRight.AddItem(PnlVehicleStatus, DockPosition.Right);

<RadDock:RadDocking x:Name="Docking" Grid.Row="2" LayoutUpdated="RadDocking_LayoutUpdated">
            <RadDock:RadSplitContainer>
                <RadDock:RadPaneGroup x:Name="RSCDockLeft">
                </RadDock:RadPaneGroup>
            </RadDock:RadSplitContainer>
            <RadDock:RadSplitContainer  InitialPosition="DockedRight">
                <RadDock:RadPaneGroup x:Name="RSCDockRight">
                </RadDock:RadPaneGroup>
            </RadDock:RadSplitContainer>
            <RadDock:RadDocking.DocumentHost>
                <RadDock:RadPaneGroup>
                    <RadDock:RadPane x:Name="PnlMain" RadDock:RadDocking.SerializationTag="PnlMain">




                    </RadDock:RadPane>
                </RadDock:RadPaneGroup>
            </RadDock:RadDocking.DocumentHost>


        </RadDock:RadDocking>

This code ends with an null reference exception being called on the additem call.

Any help in figuring out why I am getting a null reference exception would be appreciated.

Thank you in advance.

Hi Ryan,

What I suspect is that you are trying to add the pane at the right side of a pane group that is not added in a SplitContainer yet and this is not possible, because it cannot detect in which SplitContainer the new pane should be added. Only adding to the center of a pane group is allowed before the group is placed in a SplitContainer.

As I don't know what the goal is - to add the newly created pane next to the group or in it, I cannot give a concrete advise what to do. Because of the title of the thread I assume you need to add the pane in the group, so you just need to change the last line of code to RSCDockRight.AddItem(PnlVehicleStatus, DockPosition.Center);

Hope this helps.

Kind regards,
