Can't set RadPane.Header programatically after LoadLayout

[Gareth]

Hi guys,

Here's the scenario:

1. Three panes, each with their own Header text set in XAML
2. Programatically set RadPane.Header to change the pane header text. This works fine.
3. Save the layout to Iso storage
4. Refresh page. LoadLayout is called on RadDocking.IsLoaded
5. Panes are loaded back in with the Header texts that were set before saving. This is not desired, but not really a problem.
6. Attempt to set RadPane.Header again on any pane. The text will not change.
7. However, if a Pane is auto-hidden, the Header text changes in the pinned pane's tab, so it looks like setting RadPane.Header is working, just not updating in the actual pane headers.

Using version 2011.2.1031.1040

Hi Gareth,

I have a similar problem and at the moment I just unpin and pin the pane. But it is a bug I think.

Hi Jan,

Thank you for contacting us.

I would suggest setting a SerializationTag attached property to the RadPane. When the layout is loaded, all Docking parts are generated (created) and the objects defined in the xaml are not the same after the load. But we keep the instances if you set serialization tag, and in this way you will be able to change the pane header. Please, refer to the attached project that demonstrates this behavior. 

I hope this helps.

Kind regards,

The bug doesn't seem to affect Document Panes, only standard RadPanes.

I amended your above solution to change the header of the normal RadPane as follows:

<telerik:RadDocking x:Name="dock" Margin="0 30 0 0">
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup>
                        <telerik:RadPane x:Name="docPane" Header="document" telerik:RadDocking.SerializationTag="dockPane"/>
                    </telerik:RadPaneGroup>
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>
            <telerik:RadSplitContainer>
                <telerik:RadPaneGroup >
                    <telerik:RadPane x:Name="pane1" Header="pane" telerik:RadDocking.SerializationTag="dockNormalPane"/>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking>

private void Button_Click(object sender, RoutedEventArgs e)
        {
            this.docPane.Header = "document" + ++count;
            this.pane1.Header = "pane" + ++count;
        }

Clicking "Change header" after a save/load will no longer change the header of the RadPane.

Hello Gareth,

We can confirm that this is a bug in our control and we will fix it in our further development. Meanwhile, I would suggest using the RadPane.Title property instead of RadPane.Header.

I hope this suits your needs.

All the best,

I have the same problem so I changed it from Header to Title but it has the same problem. I am using version 2012.3.1129.40 of the WPF product.

I see that you fixed this ticket in 2012 Q2 but only for Silverlight. Can you please submit another ticket for WPF. Thanks

[George]

Hi Valerie,

I tried the given scenario with a sample WPF project and I was unable to reproduce this issue with the 2012.3.1129.40 version. You can find the attached project which is used for testing the given scenario. Could you please give it a try and let me know if I missed something.

i am glad to assist you further.
