Hello. I work with the diagramview 301pre in imagemap mode and the SelectAfterCreate is true. I notice the following issues. When i drop a shape on the canvas a postback is fired wich is according plan, I need to bind the netdiagram shapes with our business objects. This is done via the Tag property. But at the end of the roundtrip no shape is selected on the client. I get round this problem by setting the node.selected property to true wich makes the shape selected. In the xml from the diagram is the selected element empty until i set the node.selected to true, the xml renders the selected element correctly then. Same problems for the relations. Does this property not work in imagemap mode?
Another thing is that i want to be able to draw and delete links but not modifying (change the origin or destination). Tries several settings but it seems no to be working. A possibility is to cancel the event client or server side but i don't want to give the user the abillity to change the link.
Another point i cant figure out is blocking the resize ability of the shapes on the canvas.
Hope someone can help me.

Hi Stoyan,
I've tried as you suggested, the links are locked. The problem now is that i get a script error when i enable the ItemsDom. Tried it in ie8 and ff3. It happens when you move a shape. Select the shape to move. Handlers are set visible. Click in the middle to move it and the script error is thrown.

The error is thrown at the function

Sys.Component.create = function Sys$Component$create(type, properties, events, references, element) {
    /// <summary locid="M:J#Sys.Component.create" />
    /// <param name="type" type="Type"></param>
    /// <param name="properties" optional="true" mayBeNull="true"></param>
    /// <param name="events" optional="true" mayBeNull="true"></param>
    /// <param name="references" optional="true" mayBeNull="true"></param>
    /// <param name="element" domElement="true" optional="true" mayBeNull="true"></param>
    /// <returns type="Sys.UI.Component"></returns>
    var e = Function._validateParams(arguments, [
        {name: "type", type: Type},
        {name: "properties", mayBeNull: true, optional: true},
        {name: "events", mayBeNull: true, optional: true},
        {name: "references", mayBeNull: true, optional: true},
        {name: "element", mayBeNull: true, domElement: true, optional: true}
    ]);
    if (e) throw e; 

I've sended the code and xml via mail.

Thanks for the new dll's. It fixed then ItemsDom. However the selectaftercreate is not working. When i look at the xml the selection element is empty all the time. Even if on screen a shape is selected and its handles are shown.

Another thing i noticed (in both versions) is that i get a postback when a shape is selected and the canvas is clicked. I haven't implemented the onclick. This only occurs when there is a shape selected clientside. To repeat the error, drag a shape on the canvas. Click it to select it. Click on the canvas and there is the postback.

Hope i explained it well enough for you.

At the page init and at the page unload.

Thx for the reply. I've tried a few things but the selecting after create doesn't work properly. I saved the xml at loadcomplete and unload event. The scenario was:

[1]EmptyCanvas
[2]Drag a shape on the canvas
[3]Click a shape to select it
[4]Drag another shape on the canvas

I sended the xml's by mail.

Is there a way to make the canvas cancel the postback when the canvas is clicked for deslecting?
