We are using the OrgChartDiagram to show the organization hierarchy in our application. To export the diagram, we used the RadGeometryDropDownButton control with two options PNG and BMP.  We are using the telerik:DiagramCommands.Export command is used for that purpose. Sometimes, the options are disabled when we go to other page and back. We need to reload the page to get that option enabled. When the export command remove from the code, the options are enabled.

Please help us to resolve.

See below the code for your reference. ElementName in Command target is the org chart control name.

<local:OrgChartDiagram x:Name="diagram" GraphSource="{Binding GraphSource}"  IsBackgroundSurfaceVisible="False" Margin="10"
                            ScrollViewer.HorizontalScrollBarVisibility="Auto"
                            ScrollViewer.VerticalScrollBarVisibility="Auto"                                              
                                           IsRotationEnabled="False"                                           
                            ShapeStyle="{StaticResource OrgChartShapeStyle}" />

Hi Venkata,

It seems that this thread is duplicated. As the question regards the RadDiagram Framework we already answered this query in the other thread. Please refer to it and lets continue the communication there.

Thank you for understanding.
