Problems with the Pane DocumentHost when LoadLayout

[Weliton Flor]

Hello,

First save the layout with DocumentHost panes.

Close Browser, and run application again.

When LoadLayout, the Panes which are in DocumentHost are inverted with the header, see the image attached.

Thanks

Hello Weliton,

 This only happens if you didn't set the RadDocking.SerailizationTag attached property to the pane. If you don't set this property the Save/Load layout won't be able to load the content of the pane as well so most probably you will need to set this property. For more information about how to use the Save/Load layout feature of the Docking control you could refer to the following blog post: http://blogs.telerik.com/miroslavnedyalkov/posts/09-04-22/raddocking_save_load_layout.aspx

We will fix the problem for one of the upcoming releases.

Hello,

I'm already doing this, set the SerializationTag for all windows.

You have an example of DocumentHost save, close the browser and reopen when it loads correctly?

Thanks

Hello Weliton,

What I observed is that the panes with no serialization tag behave like you said, but these with serialization tag set behave correctly. Please find the attached project.

Hello,

I tried putting the SerializationTag but do not work.

I am sending a sample (download here), do the following:

- Run the project
- Create a Pane
- Save the Layout
- Close the project

- Rerun the project
- Load the layout
** At this point the problem will occur.

Thanks

Hi Weliton,

 Now I was able to reproduce the issue and was able to find a work-around. What I did was to change the code of the Area_ElementLoaded method to the following:

private void Area_ElementLoaded(object sender, LayoutSerializationEventArgs e)
{
    if (e.AffectedElement.GetType().Name == "RadPane")
    {
        var pane = (RadPane)e.AffectedElement;
        pane.Content = new Control1();
        pane.Dispatcher.BeginInvoke(() =>
            {
                if (pane.IsInDocumentHost)
                {
                    pane.Template = ((RadPane)e.AffectedElement).DocumentHostTemplate;
                }
            });
    }
}

I will log the issue and we will fix it for one of the upcoming releases.

Best wishes,
