Hiding group handles

[GC]

Is it possible to hide (set to transparent?) group handles. By group handles I mean the handles that appear when 2 or more nodes are selected.

Hi GC,

Thanks for using Syncfusion products.

We suggest you to set the view “HandleColor” and “HandleOutlineColor” property to transparent to achieve your requirement.

Please refer the below code snippet:
[C#]

this.diagram1.View.HandleColor = Color.Transparent;
this.diagram1.View.HandleOutlineColor = Color.Transparent;

For your convenience, We have created a simple sample to demonstrate the above and the same can be downloaded from the below link:

Please let me know if you have any concerns.

Hi Gc,

Thanks for using Syncfusion products.

Whenever you select more than one node the group handle only visible.We suggest you to set the view's "HandleColor" and "HandleOutlineColor" property to transparent to acheive your requirement.

Please refer the below code snippet:
[c#]

private void Form1_Load(object sender, EventArgs e)
{

this.diagram1.MouseUp += new MouseEventHandler(diagram_mouse); 
}

private void diagram_mouse(object sender, System.Windows.Forms.MouseEventArgs e)
        {
            NodeCollection nodes = this.diagram1.Controller.SelectionList;

            if (nodes.Count > 1)
            {
                this.diagram1.View.HandleColor = Color.Transparent;
                this.diagram1.View.HandleOutlineColor = Color.Transparent;
                
            }
            else
            {
                this.diagram1.View.HandleColor = Color.GreenYellow;
                this.diagram1.View.HandleOutlineColor = Color.Black;
            }
        }
