I have created a webpage that uses the Java version of DiagramView. I am now looking to use the Silverlight version instead.

Are there any major issues with this? I have already hit one, where the AppletStartedScript does not run once the silverlight control is loaded.

Hi Stoyo,

Thank you for that. I might have to wait for the next version - I'm not very good at silverlight/wpf !

We are actually debating over whether to use java or silverlight. The silverlight looks much cleaner on the page.

If I give you a list of functionality I am looking for, could you just copy/paste and say yes/no to if these are possible in silverlight?

I am looking to do all of the following using javascript:
1. A Treeview layout with horizontal and vertical links (not diagonal)
2. Ability to zoom in and out using javascript
3. Ability to create a group with a number of shapenodes through javascript
4. Ability to create/change a shapenode's id, text, fill and border through javascript
5. When the shapenode's text is too large, then adjust the height of the shapenode accordingly. (keeping the width the same)
6. Ability to detect which shapenode the user has clicked on, and create a new shapenode linked to the clicked shapenode (or delete the shapenode). Also ensure that the layout is followed after the new shapenode is added.
7. Ability to export the diagram as an image

What would also be nice is the following:
a. Ability to initiate an AJAX call or javascript call when a event happens (such as when a shapenode is added).

1. I can't find a way to instantiate a Silverlight TreeLayout object from JavaScript. It seems we'll have to add a ScriptHelper object similar to what we have in the jdiagram.jar applet to let you create layout instances. You can still run TreeLayout on the server to get the expected layout.

Hi,

You can enable whole-word text wrapping in Java too.

If you have decided to implement everything in Silverlight, note that it does not support grouping yet, but perhaps you can use ContainerNodes instead. If you need the AttachTo method, our developer can port it to Silverlight next week.

You can unzip the diagramming.silverlight.dll from ClientApp.xap (xap files are in zip format). If you PM me your account name at http://clientsarea.eu/, I can also add the DiagramLite installer to the account so you'll have Silverlight-specific samples and help file.

Hi Stoyo,

After trying to use container nodes, it looks like I do need the AttachTo method. Could you please organise it to be ported over?

I have been trying to use container nodes. I have created links between the nodes within the container nodes. I want to rearrange these in a treelayout. When I try this, I get the following error message:

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.

Hi Stoyo,

As I was trying to port my javascript to vb.net, my code was similar to below (but in vb.net):


       function redrawLayout()
       {
           var tl = script.createTreeLayout();
           tl.setLinkStyle(2);
           tl.arrange(diagram);
           diagram.resizeToFitItems(10.0, true);
       }

I think it was:

dim tl as treelayout
tl.linkStyle = Cascading3
tl.arrange(diagram)

This version adds an AttachTo method:
http://mindfusion.eu/Forum/YaBB.pl?board=diaglite_disc;action=display;num=132377...

It only lets you attach nodes to nodes at this time.

I hope that helps,
Stoyan
