How can I pass a text string to some property of a ShapeNode that can be accessed by javascript when a user clicks the node?  (I do not wish this text to be displayed until the user clicks.)

I have been experimenting to see if I could at least display the node's label text in a popup box.  I have tried "args.getNode().getText();" which produces an "object required" error.

I have been working with NetDiagram for only a few days.  I'm enjoying learning NetDiagram and I hope someone can help me over this hump.

Thanks.

Thank you once again, Stoyan. .getTag() is just what I was looking for, and I was pleased to see that it accepts arrays, which will be very useful to me.

I have also been unable to use the getMouseButton method, I suppose for the same reason. Is there a way to determine which mouse button was used without loading the java applet?

I'm unclear on how to use the CreateAreaElement event for my purpose, which is to launch one javascript function when the user left-clicks a node and a different javascript if the user right-clicks. A bit of sample code would be greatly appreciated.

Thanks.

I downloaded the files from the posting you directed me to and I substituted the three dll's in my bin folder with the new ones in the zip file.

I found that VWD would not accept the type "CreatingAreaElementEventArgs", so I defined e simply as an object in my vb code as follows:

Protected Sub DiagramView1_CreatingAreaElement(sender as object, e as object)

e.Attributes("onmousedown") = "return onMouseDown(event)"

End Sub

This compiled and ran without an error, but the code never executed. (I presume it's supposed to run each time a node or connector is created, is that right?)

Is there something else I should be doing to get this to run? I assumed that the object called "view" in the sample code is a DiagramView object, is that correct?

I deleted the three dll's from the bin folder, as you suggested, and I re-referenced them, and now the "CreatingAreaElement" method does appear on the list of available methods for DiagramView1.

However, a new problem came up. When I try to run the file now, I get an error: "'TreeLayoutDirection' is not declared". You may recall that I had this problem earlier, and the solution was to add the line "Imports MindFusion.Diagramming.Layout".

Is there an additional Imports that I must add to regain access to TreeLayoutDirection?

Thank you, Stoyan.  I believe I now have all the info I need to get started.  I appreciate yor help very much.

AFAIK, this can be done only on the server side when using image map mode. You could put the DiagramView inside an UpdatePanel to prevent postback of the whole page, and only the diagram image will be refreshed.

I hope that helps,
Stoyan
