Use of SuspendExpandRecalculate property
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
