Hi,

I am using Asp.net 2.0 treeview control.Tree is having 2-3 level of 
hirearechy. I want to show current selected node as expanded when the page 
reloads or postback. How can I do that?

Thanks

Hi,

Try this :
protected void tv_PreRender(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
	if (tv.SelectedNode != null)
	     tv.SelectedNode.Expand();
        }
    }

Hi Vikram,

try to set SelectAction in your nodes to Expand. Be aware of impact on 
TreeView functionality. Changing SelectAction can affect which events are 
fired when user click on node. For expand mode it will not fire 
SelectedNodeChanged any more.

You can also handle SelectedNodeChanged, collapse all nodes and then expand 
only selected node if you want to.

Regards,
Ladislav
