Hello,

I am trying to produce a Diagram like the ShapeListBox demo where a user can build/modify their own diagram. I need to use ImageMap mode and I am unsure how to duplicate some of the behavior in the JavaApplet.

For instance, in the demo a single click allows move/resize and a click+drag will link objects. In ImageMap mode I only seem to be able to have 1 set of behavior at a time. Also, I did not see a BehaviorBase class that applied to ASP.NET.

Is there anywhere I can download sample/example code using ImageMap mode? I am especially interested in user created/modified diagrams.

Thank you,

Hi Stoyan, thank you for your quick reply.

I am actually referring to the ShapeListBox example where the user can build a custom diagram by dragging the shapes onto the diagram itself. 

The DiagramView.Behavior = MindFusion.Diagramming.Behavior.LinkShapes is not giving me the behavior that I am seeing in the demo on the webpage.  When I single click a shape it draws a link to itself and does not allow me to resize / move the shape.  I would like the user to be able to:

* Drag new shapes onto the Diagram from a ShapeListBox.
* Single click shapes to resize / move them.
* Click and hold to draw links between shapes.
* NOT be able to draw new boxes on the diagram, all shapes should come from the ShapeListBox.

I see behavior close to what I need in the applet example but I am not sure how to duplicate it using ImageMap mode.  Is there anything I can do? 

Thank you.

Hi Stoyan,

With the latest code and diagramView.Behavior = Behavior.DrawLinks I am getting the behavior that I was looking for. Thank you.

However, I have run into another issue. I am trying to handle serverside events in ImageMap mode but they never seem to fire. I have the code:



<ndiag:DiagramView ID="diagramView" runat="server" Height="512px" Width="512px"



ClientSideMode="ImageMap" ShowScrollbars="false">



<Diagram AllowSelfLoops="false"




OnNodeDoubleClicked="Diagram_NodeDoubleClicked"




OnNodeClicked="Diagram_NodeClicked"




OnLinkClicked="LinkClicked" />


</ndiag:DiagramView>

I have the 3 event handlers implemented in my C# code-behind but yet they never fire. Is there something I am missing?

I have also tried hooking them up using:
diagramView.Diagram.NodeClicked += new NodeEventHandler(Diagram_NodeClicked);

This does not seem to work either.

Thank you,

Ok Stoyan, thank you for the information (and the quick reply).
