Hi,

1. There are CopyToClipboard, CutToClipboard and PasteFromClipboard methods available in the Silverlight 4 build of the control.

2. Use the SaveToPng method or CreateImage with third party encoders (see http://mindfusion.eu/Forum/YaBB.pl?num=1328022990/1#1)

3. Set Diagram.UndoEnabled.

I hope that helps,
Stoyan

Hi Stoyo
Thanks for your reply,

Can you please tell me one more thing :
I am looking for one scenario like if user drops a Shape1 from toolbox on another Shape2 in diagram then
this will create a connection between
Shape1 (destination) to Shape2 (origin)

Will this be possible? if yes Can you please provide some samples

Thanks again Smiley

Hi,

That's shown in the TreeLayout sample project, here's a part of the MouseUp handler:

Code
Select All
Point diagramPosition = e.GetPosition(diagram);
DiagramNode parent = diagram.GetNodeAt(diagramPosition);
if (parent != null)
{
	ShapeNode child = new ShapeNode(diagram);
	child.Image = draggedImage.Source;
	diagram.Nodes.Add(child);

	DiagramLink link = new DiagramLink(diagram, parent, child);
	diagram.Links.Add(link);
	...
}


I hope that helps,
Stoyan

Yes, that's work perfectly.

In the same case :
Shape 1 (Origin) connected with Shape 2 (destination)
Now If I drag a shape3 & drop on connected link of Shape 1&2 then
diagram should get break & this should become

Shape1 ---> Shape3 ---> Shape2

How can I do this case?

Something like

var oldLink = diagram.GetLinkAt(...);
var shape3 = diagram.Factory.CreateShapeNode(...);
diagram.Factory.CreateDiagramLink(oldLink.Origin, shape3);
diagram.Factory.CreateDiagramLink(shape3, oldLink.Destination);
diagram.Links.Remove(oldLink);

I hope that helps,
Stoyan
