What populates the AffectedElementSerializationTag?

[Trevor Leybourne]

Hi there, I am trying to define a Load/Save Layout with content function and my event only returns a null AffectedElementSerializationTag. What populates this value?

My code is as follows:

        private string GetLayout()
        {
            using (var stream = new MemoryStream())
            {
                docking.ElementSaved += ElementSaved;
                docking.SaveLayout(stream, true);
                docking.ElementSaved -= ElementSaved;
 
                stream.Position = 0; 
                using (var reader = new StreamReader(stream)) {
                    return reader.ReadToEnd();
                }
            }
        }
        void ElementSaved(object sender, LayoutSerializationEventArgs e)
        {
            var pane = e.AffectedElement as RadPane;
            if (pane != null)
            {



                //pane.Content = this.GetPaneContent(e.AffectedElementSerializationTag);
            }
        }

In the above, e.AffectedElementSerializationTag is always NULL.

I have worked this out. This can be set through XAML as a dependancy property on the RadDocking control for the Pane or through code by using the SetValue method to set the DependencyProperty. There is no exposed public property to set this value directly in code.

Hi Trevor,

 Yes, we decided to make the SerializationTag an attached property. You could read more about this in the following help article: http://www.telerik.com/help/silverlight/raddocking-features-save-load-layout.html.
