Hi,

I am new to Telerik controls. I have tried to replicate the OrgChart sample and with simple collection. The Nodes and its links are not rendered correctly. I hereby attached the sample application which i have created.

Hi Kannan,

 The RadDiagram must have prepared it's containers - (RadDiagramShapes and RadDiagramConnections) before invoking Layout and Routing methods. So instead of MainPage.Loaded, you can use the Diagram Loaded (which will fire later) and even add a Dispatcher to ensure the creation of the shapes.

this.GraphSource = new GraphSource();
    this.PopulateWithData();
    this.PopulateGraphSources();
    this.DataContext = this;
    GetViewModelAndBindForEvents();
    this.diagram.RoutingService.Router = this.router;
    this.treeLayout = new TreeLayout();
    this.diagram.Loaded += new RoutedEventHandler(diagram_Loaded);
    //this.diagram.Connections.ForEach(x => RadDiagramConnection.SetIsAutoUpdateSuppressed((RadDiagramConnection)x, true));
    //this.diagram.Connections.ForEach(x => RadDiagramConnection.SetIsAutoUpdateSuppressed((RadDiagramConnection)x, false));
    //this.diagram.Connections.ForEach(x => x.Update());
     
}
 
void diagram_Loaded(object sender, RoutedEventArgs e)
{
    SetLayoutRoots();
    Dispatcher.BeginInvoke(()=>
     this.LayoutOrgChart(false));
}
 
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    //SetLayoutRoots();
   // this.LayoutOrgChart(false);
}
You can find this realized in the attached solution. Please let us know if the suggested approach is suitable for you. Greetings,
