GroupNode Expand or Collapse

Diagram control have built-in support to expand/collapse the nodes by using Node’s “IsExpanded” property. We can enable/disable the node’s “IsExpanded” property to expand/collapse the child node of the current node. This behavior works fine within the group node too.

The following code illustrates to expand the parent node:

[C#]

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

 

[VB]

Dim rect As New Syncfusion.Windows.Forms.Diagram.Rectangle(100, 100, 100, 100)
rect.IsExpanded = True

 

The following code illustrates to collapse the parent node:

[C#]

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

 

[VB]

Dim rect As New Syncfusion.Windows.Forms.Diagram.Rectangle(100, 100, 100, 100)
rect.IsExpanded = False
