How to expand all the child nodes of the selected TreeNodeAdv programatically?

In the TreeViewAdv, TreeNodeAdv can be expanded by using the Expand and ExpandAll functions.

  • Expand: This function helps to expand a particular TreeNodeAdv.
  • ExpandAll: This function helps to expand the node and all its sub nodes.


To expand all the child nodes under the selected TreeNodeAdv programmatically, follow the steps:

  1. Handle AfterSelect event that is triggered when the TreeNodeAdv is selected.
  2. Iterate the TreeNodeAdvCollection, and invoke the Expand function.


The following code example demonstrates the same.
