Load on Demand - Expand Node programaticly

[Dirk Eberhardt]

Good Morning,
I've created a RadTreeView with Data from a SQL Table. I load the Data on demand like in this example (Client Side):

http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/loadondemandmodes/defaultcs.aspx

How can I expand a path to a spacial Childnode programaticly?

I tried it with:

RadTreeView.FindNodeByValue("NODEVALUE").ExpandParentNodes();

But that doesn't work. I think beacause the data is not loaded at this time.

Any ideas how to do that?

Thanks in advance

Regards
Dirk

Hello,

Given the node you want to expand, you need to do something like this:

var parent = node.Parent;

while(parent != null)
{
   parent.Expanded = true;
   parent = parent.Parent;
}

Put this somewhere after you add your node as child node in the method that creates the node.
