A 'new' type of binding problem?

[Stuart Hemming]

We're using a treeview to provide a navigation tool.

At a certain level we want to display some hierarchical data.

Can any one think of a straightforward way of adding hierarchical data to a node in an existing tree without destroying the existing nodes?

Hello Stuart Hemming,

RadTreeView does not provide bult-in support for this scenario. However I can propose a workaround:

1. Creating a temporary RadTreeView object and bind the data to it
2. Traverse all root nodes of the temporary treeview and add them to the existing node in the original treeview

Albert,

Cracking! I didn't think I'd be able to just move nodes like that.

I added an extension for the RadTreeNode class like this...

	namespace UEAPL.Shared.Extensions
	{
	public static class RadTreeNodeExtensions
	{
	public static void AddHierarchy(this RadTreeNode node, object DataSource, string DataTextField, string DataValueField, string DataFieldID, string DataFieldParentID)
	{
	RadTreeView t = new RadTreeView();
	t.DataTextField = DataTextField;
	t.DataValueField = DataValueField;
	t.DataFieldID = DataFieldID;
	t.DataFieldParentID = DataFieldParentID;
	t.DataSource = DataSource;
	t.DataBind();
	while (t.Nodes.Count > 0)
	{
	node.Nodes.Add(t.Nodes[0]);
	}
	}
	}
	}
