How to get connected shapes for any selected Shape?

[Shrikant]

Hi,
I want to know, how can I get child nodes for selected shapes?
For e.g.
A ---> A1-->A3,A4
A ---> A2-->A5,A6
Here A is root with two child's A1,A2.
So if I select A1 then I want to know which shapes are connected (i.e. outgoing links connected shapes from A1).

Hi Shrikant,

You can iterate over the items through items, shapes or connections. After getting a list, you can then look at the list of items and take it from there.

This link will bring you to the documentation on iteration of diagram items. Below is an example of how you would do it:

this.diagram.Shapes.ToList().ForEach(x =>
    {
        //your custom logic goes here
        (x as RadDiagramShape).Content = "Shape";
    });

Good Luck,
Lancelot

Hi Shrikant,

 There are some Extensions methods that you can use - GetConnectionsForShape(this IGraph graph, IShape shape) or IEnumerable<IConnection> GetOutgoingConnectionsForShape(this IGraph graph, IShape shape).
So the code will be something like this: 

var connectedShapes = diagram.GetOutgoingConnectionsForShape(myShape).Select(c => c.Target);

And the connectedShapes will contain the outgoing shapes of the myShape shape.

Kind regards,

Hi Miro,
In current version of RadDiagram, I didn't found such a method to get connected shapes.
Can you check & tell me.

Thanks

Sorry my mistake, assembly missing - "Telerik.Windows.Diagrams.Core"
