Hi,

ShapeNode derives this property from ContentControl, and I don't think it's a good idea to touch it. You can create a user control and host it inside ControlNode objects if you need nodes that look very different from ShapeNode.

Thank you Stoyan for the quick reply.

For now I will try to implement that workaround  you have suggested.

Do you have an estimation for when will the 1.0.2 version will be released?

Hi Stoyan
Thank you for that, I will look for that release.

I'm also trying to manipulate the border of the node using BorderThickness and BorderBrush but I do not see the effect in the visual display.
This is my code:

Thickness tmpThick = new Thickness(3, 3, 3, 3);
NewNode.BorderThickness = tmpThick;
NewNode.BorderBrush = new SolidColorBrush(Colors.Red);

What am I doing wrong ?

Hi Stoyan

Thanks for your reply.
What I actually need is something to visually show a Valid/Invalid node.
So I thought about a thick red/green border but could not find a way to do it using pen...(any ideas ?)
I also thought of adding a small X or V icon. I drilled into the content of the node (into its internal grid) and added a small icon... but it didn't show on the UI. Is this approach possible ? any other options ?

+ I have a few more things that I cannot figure out…..

1. Is it possible to copy/paste a node using the clipboard ?

2. I added the ability to drag the entire workspace.  When I try to change the cursor in the application like
Cursor = Cursors.Hand;
It is changed in my application. When it first enters the diagram all is well but after clicking it is changed into an arrow, no matter what I do, like:
(fCartTst is my diagram)

    private void fCartTst_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
       {
           if (isDraggingWorkspace == true)
           {
               Cursor = Cursors.Hand;
           }
           else
           {
               //Disable free writing on the diagram
    fCartTst.Behavior = Behavior.DoNothing;
           }
       }

       private void fCartTst_MouseMove(object sender, MouseEventArgs e)
       {
           if (isDraggingWorkspace == true)
           {
               Cursor = Cursors.Hand;
           }
       }
3. The diagram have this property -  KeyDown="fCartTst_KeyDown"
This event does not fire.
Also tried that…
NewNode.KeyDown += new KeyEventHandler(NewNode_KeyDown);
Nothing fire. Any ideas ?

Regarding your other questions:

1. There is no clipboard support in Silverlight 2. For copying a single node, you can use the copy constructors we added to v1.0.1. For copying multiple nodes and links, we could add copy/paste methods to let you at least copy between diagram objects in the same Silverlight application.

2. Try also setting Diagram.Cursor.

3. You might have to TAB a few times to move the keyboard focus to the diagram. We'll also add a method to let you set it programmatically.

Hi Hai,

Your copy function might just save a reference to the ActiveItem, and the paste function could do something like this:

if (itemToCopy is ShapeNode)
{
	ShapeNode node = itemToCopy as ShapeNode;
	ShapeNode copy = new ShapeNode(node);
	diagram.Items.Add(copy);
	copy.Bounds = new Rect(...); // based on mouse position
}
 

I hope that helps,
Stoyan

1. TextFormat is not implemented yet, and that XML was saved from the Windows Forms version Anyway we'll try to implement support for templates in the next few days.

2. There is no support for encoding images in Siverlight, so we haven't implemented this. We got permission from Joe Stegman to use his PNGEncoder in DiagramLite, and will add image serialization to the next version

3. Are you applying these properties to the Diagram, or to the ScrollViewer?
