How to get value of DataFieldParentID

[Sanjoy]

Hi,
I am using Treeview with combobox.
When we select any child node from hierarchy then how we will get "DataFieldParentID" value, Using Javascript and serverside programming. Please help me. It is urgent in our project requirement.

Thanks and Regards,

Hello Sanjoy,

Try the following code to achieve your scenario.
1) From server side:
C#:

protected void RadTreeView1_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
  if (e.Node.ParentNode != null)
  {
    string value = e.Node.ParentNode.Value.ToString();
  }
}

2) From client side:
JS:

function OnClientNodeClicked(sender, args)
{
 if (args.get_node().get_level() != 0)
 {
    alert(args.get_node().get_parent().get_value());
  }
}

Thanks,
Shinu.
