Data in the stackpanel is duplicated on Tab changed

I have some stackpanel within RadTabControl. Let me give an overview of one such stack panel.
  
<telerikNavigation:RadTabControl x:Name="tabControl" Height="Auto" Background="Transparent" Margin="0,0,0,10" BorderThickness="0">

<telerikNavigation:RadTabItem Header ="Technical">
<StackPanel x:Name="AssociateReportsPanel" Orientation="Vertical" Margin="0,5,0,0"/>
 </telerikNavigation:RadTabItem>

 

In code behind.. On Page load, I call a webservice and then on even completed I populate the stackpanel with a control as follows.

AssociatedReportsCustomListControl = new CustomListControl("Associated Reports", e.ScorecardMeasure.AssociatedReports);  
AssociateReportsPanel.Children.Add(AssociatedReportsCustomListControl);

Every time I change the Tab and then come back, the control within stackpanel is added again. How can I overcome this issue

Hi Rocky Fernandes,

The Loaded event fires whenever an object is added to the Visual Tree and indeed this is different than the general perception of "loaded". What you can do is flag the web service call and the loading so that it will happen just the first time the loaded is fired.
