How to make a readonly diagram ?

Hi

I want to make diagramView readonly in some cases. It means to avoid users to create or change the diagram nodes and links and their positions.

I tried to do this by setting Behavior property to DoNothing in server side but it dosen't work! I use diagramView in JavaApplet mode and use ShapeListBox to add custom nodes to the diagram.

Is there ReadOnly property to both diagramView and shapeListBox?

Thank you.

Hi,

Behavior only specifies what happens when you draw on the canvas with the mouse. Do you need to disable creating nodes using drag-and-drop from the ShapeListBox?

Yes. All changes in diagram including drag&drop, delete, change positions and so on.

Diagram is a field in my form and when form is in view mode I should make all fields read only. 

Is there a solution?

You could set ClientSideMode to ImageMap. The diagram can't be modified then, unless you add an InteractivityExtender.

I hope that helps,

I tested your approach but it doesn't work. I changed the ClientSideMode to ImageMap in onClick evnet of a button on the form. The initial mode is JavaApplet.
But I can change the diagram still.

Is the Java console icon displayed after you hit that button? If it's still there, perhaps there's some code that changes the mode back to JavaApplet later. If you can't see it anymore but can move nodes, then you probably have the InteractivityExtender enabled on that form.

Hi
You can try this:


ClientSideMode.JavaApplet

1.Edit Mode

diagramView.ClientSideMode = ClientSideMode.JavaApplet;
diagramView.Enabled = true;
diagramView.Behavior = Behavior.DrawLinks;
               shapeList.ClientSideMode = ClientSideMode.JavaApplet;
foreach (DiagramNode node in diagram.Nodes)
{
node.EnabledHandles = AdjustmentHandles.All;
}


2.Read-only Mode:

diagramView.Enabled = false;
diagramView.Behavior = Behavior.DoNothing;
diagramView.NodeClickedScript = String.Empty;
shapeList.ClientSideMode = ClientSideMode.ImageMap;
diagram.ActiveItem = null;
foreach (DiagramNode node in diagram.Nodes)
{
node.EnabledHandles = AdjustmentHandles.None;
}
