Hi Kamel,

 

Thanks for using Syncfusion products.

 

We have created a simple sample to update the labels of a node in the NodeDoubleClick event of the DiagramWebControl and the same can be downloaded from the below link.

 

Here is the code:

Syncfusion.Windows.Forms.Diagram.Rectangle rect = new Syncfusion.Windows.Forms.Diagram.Rectangle(100, 100, 100, 70);

                rect.Labels.Add(new Syncfusion.Windows.Forms.Diagram.Label(rect, "Rectangle Node"));

                DiagramWebControl1.Model.AppendChild(rect);

 

                LineConnector line = new LineConnector(new PointF(100, 250), new PointF(300, 250));

                line.Labels.Add(new Syncfusion.Windows.Forms.Diagram.Label(line, "LineConnector") { OffsetX = 30, OffsetY = 5 });

                DiagramWebControl1.Model.AppendChild(line);

 

protected void DiagramWebControl1_NodeDoubleClick(object sender, Syncfusion.Web.UI.WebControls.Diagram.NodeDoubleClickEventArgs e)

        {

            if (e.Node is PathNode)

            {

                PathNode node = e.Node as PathNode;

                node.Labels[0].Text = "Node DoubleClicked";

            }

        }

Here is the sample:
