What is the use of the SuspendExpandRecalculate property?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

By setting SuspendExpandRecalculate property to true,the user can improve the performance of the TreeViewAdv with large number of nodes.Generally the time takento populate 5000 childnodes to a RootNode takes 10 ms but after setting the SuspendExpandRecalculate to true,the time taken for populating is decreased to half of its original time i.e, 5 ms.

The unnecessary calling of Recalculate dimensions for the child nodes when the Root nodes are collapsed is also reduced.Thus the performance of the TreeviewAdv can be improved.

C#

this.treeViewAdv1.SuspendExpandRecalculate=true;

VB

Me.treeViewAdv1.SuspendExpandRecalculate=True
