Is it possible to prevent a postback for certain shapes ???? Somehow i am not able to find it .

excerpt code

                       ShapeNode MasterNode = (ShapeNode)diagram.FindNode(NodePrefixType.ShowUnitDetails + fromId);
                       
               

                       ShapeNode footerNode = diagram.Factory.CreateShapeNode(MasterNode.Bounds.X ,
                                                                               MasterNode.Bounds.Y - 4, 4, 4);
                  
                       //MasterNode.AttachTo(footerNode, AttachToNode.TopCenter);
                    
        footerNode.Image = "ImgProcess.gif";
                       
         footerNode.Transparent = true;
         footerNode.ImageAlign = ImageAlign.Center;

         footerNode.ResizeToFitImage();
                  
                 Thanks

Are you using Flowchart.NET and the HtmlBuilder class? In that case, setting Hyperlink to an empty string should be enough to prevent postback.

I tried this but it gives me an error
"Object reference not set to an instance of an object."


I'm using latest version of Netdiagram.

Definition in page
<ndiag:diagramview
                       id="m_diagramView"
                       runat="server"   
                       Visible="false"
                       ClientSideMode="ImageMap"
                       OnNodeClicked="HandleDiagramNodeClick"
                       Behavior="DrawShapes"
                       ShowScrollbars="True">
                   </ndiag:diagramview>

Are there other possibilities
Thanks !!!!

In Netdiagram you can disable postback for some node by setting its Hyperlink to "javascript:void(0)". Setting the Hyperlink value will cause a NullReferenceException only if your DiagramNode variable is not initialized.

I hope that helps,
Stoyan
