Tree View in ASP.NET

[Rajesh Kumar Chekuri]

hi........ we are working on tree view but the problem is tree view is expands every node but i want only one node expands every time, mean if already one node is expanded then we try to expand another then automatically other nodes are collapsed .. Waiting for Response ..............

Not very clear on what you want. So if one node is expanded already and if you try to expand another node, then do you require all the remaining open nodes should be collapsed or it should remain open?

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

yes..... all the remaining open nodes should be collapsed

So capture the open event, and close all the other nodes in code.

You could achieve this easily by using the CollapseAll method from the tree view and then, on the clicked node you could do thisNode.Expanded = true, and recursively do this for all the parents he has using the Parent property. For instance,

youTree.CollapseAll();

.. on the event

TreeNode currentNode = nodeFromEvent;
while(currentNode != null)
{
currentNode.Expanded = true;
currentNode = currentNode.Parent;
}
