Rad Docking Performans Problem

[Murat]

Hi when I adding new RadPane to my RadPaneGroup memory usage is increasing its normal but when i close it Im using 

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
But my memory usage is same.
And I open same pane with same content memory increasing again.

RadPane pane = new RadPane
   {
       Header = "Header",
       Tag = "btnCalisma"
   };
   pane.Content = new WorkTimeReport(null);
   pane.Unloaded += new RoutedEventHandler(pane_Unloaded);
   this.PergoDock.HaritaGrubu.Items.Add(pane);

void pane_Unloaded(object sender, RoutedEventArgs e)
      {
          (sender as RadPane).Unloaded -= pane_Unloaded;
          (sender as RadPane).RemoveFromParent();
          GC.Collect();
          GC.WaitForPendingFinalizers();
          GC.Collect();
      }

        }

        public virtual void Dispose()
        {

        }
    }
}

How can I solve this problem ?

Hi Murat,

 When the panes of the Docking control are closed they actually stay in the Docking control (they are just hidden). In order to dispose them you need to remove them from their PaneGroup. In this case we are aware of an issue with the last pane in the group - it is not disposed until another pane is placed in the group, but this happens only for the last pane. This issue is fixed in the Beta version we recently released.

Hope this information is helpful.

Best wishes,

Im already removing Radpane from the parent RadpaneGroup but Problem is not solved for me.
Its same, memory usage is increasing again.
You can see details on example code.
Your explanation Is not helpfull for me but thanks anyway.

Hi Murat,

 Could you please prepare a sample project that demonstrates the performance problem you are observing and to give us some instructions how to observe the problem? This will help us identify the source of the problem and to help you overcome it.

Kind regards,
