How do I get the selected nodes in a diagram

[David Jackson]

what I was to do is apply a function to all the nodes selected, say change the back colour of the node

e.g. I want to do something like this

foreach (Node n in Diagram1.Model.Nodes)

{

     if (n.Selected)

     {

          n.BackColor = Color.Blue;

     }

}

Hi David, 

 

Thanks for contacting Syncfusion support. 

 

In order to achieve your requirement, we suggest you to use Node.FillStyle’s “Color” property to define the color of the Node. please refer to the below modified code. 

 

Modified code: 

 

[C#] 

 

Your Code	Modified code
foreach (Node n in Diagram1.Model.Nodes)  {       if (n.Selected)       {            n.BackColor = Color.Blue;       }  }	foreach (Node n in Diagram1.Model.Nodes)  {       if (n.Selected)       {            (n as FilledPath).FillStyle.Color = Color.Blue;       }  }

Hi I think you misunderstand. I can find no way to actually get the selected nodes

Contrary to the documentation the IsSeleced property for a node does not exist

Hi David, 

 

Sorry for the inconvenience caused. 

 

We don’t have in-built options to identify whether a node has been selected or not. However, we can use Diagram.View.SelectionList’s “Contains()” method to identify whether the node has been added in selection list. Please refer to the below modified code example. 

 

Code example: 

 

[C#] 

 

foreach (Node node in diagram1.Model.Nodes) 

{ 

if (diagram1.View.SelectionList.Contains(node)) 

 (node as FilledPath).FillStyle.Color = Color.Blue; 

}
