i created a same project as sample project given by syncfustion (Simplediagrm). but .edd file is not shown in the DiagramWebControl1.

If Me.IsPostBack = False Then
Dim path As String = Server.MapPath(String.Empty)
path = path + "\App_Data\SimpleOrgChart.edd"
End If
Me.DiagramWebControl1.RenderImageMap = False

what may be the reason?

Hi chi,

Sorry for the delay in responding.

How to display a diagram (.edd) in a diagram web control

The DiagramWebControl uses a custom HTTP handler for processing client requests for rendering the diagram image on to the web page.

Please add the following HTTP handler in your web.config file:


$add verb="*" path="diagram_renderer.aspx" type="Syncfusion.Web.UI.WebControls.Diagram.DiagramRenderHandler, Syncfusion.diagram.web, Version=, culture=Neutral,PublicKeyToken=3d67ed1f87d44c89"/>
$add verb="*" path="samplebrowser.ashx" type="SourceCodeTab.SourceHandler,SourceCodeTab,Version=, culture=Neutral,PublicKeyToken=3d67ed1f87d44c89"/>

Note: We have used "$" symbol instead of "<".

Please refer the sample in the below link which illustrates the above:


Please let me know if you have any concerns.
