How to databind using datatable under a default root node

[CSurieux]

Hello,

As I don't know if I will have content in the datatable I am using as a hierachical datasource for a radtreeview, I want to always have a root node on level 0 and have the hirarchical databinding occuring from level 1.
This to allow adding first node with a contextmenu 'Add' method.
How to do this in codebehind (c#)?
Thanks.

Hello Christian Surieux,

This is not supported out of the box. I suggest you first databind your treeview and then add a new root node and make all other root nodes its children. Here is some sample code:

treeView.DataSource = GetDataTable();
treeView.DataBind();

RadTreeNode rootNode = new RadTreeNode();

while (treeView.Nodes.Count > 0)
{
    RadTreeNode node = treeView.Nodes[0];
    rootNode.Nodes.Add(node);
}
