Question

Is there a way to scroll the selected node of an ASP.Net TreeView into view after a postback?

In my parrticular scenario the control is repopulated after each postback.

Thanks!

I figured it out. The TreeView control creates a javascript object on the client. It is named whatever you called the treeview with a ‘_Data’ appended. The object lets you get a reference to the selected node.

The code below uses the ASP.Net Ajax extensions. Just remember to change the TreeView name to whatever you called yours.

var name = myTreeView_Data.selectedNodeID.value; var selectedNode = $get(name);  if(selectedNode) {  selectedNode.scrollIntoView(true); }
