I have a treeview control on *winform applica*tion. Here, what I want to do is:
Collapse all other nodes at his level and expend only selected node.
For example, suppose the scenario:
– All Subject
+ Computer Science
+ Mathematics
Root Node is "All Subjects" and two child nodes are 1) Computer Science and 2) Mathematics.
These two child nodes have further child nodes.
When I select Computer Science, teh Mathematic node should be collapsed and Computer Science Node should be expanded.
How can this be achieved ?
Suggestion to accomplish this are welcomed.
