RadTreeView refreshes to top of tree NodeExpand

[Jonathan]

Hi

We have a RadTreeView registered as below:

<radT:RadTreeView ID="cRadTreeView" EnableViewState="true" style="Z-INDEX:999" Runat="server" BeforeClientClick="BeforeClickHandler"
	Checkboxes="true" DragAndDrop="true"></radT:RadTreeView>

I've been trying to put a fix in place to stop the tree refreshing back to the top after a Node has expanded. I am registering the NodeExpand event in the OnInit of the page and that event carries out the following code, is there a way for the tree to switch focus to the node that was previously expanded?

Guid expandedNodeID = new Guid(e.NodeClicked.Value);
			this.DataSource.ExpandNode(expandedNodeID);
			RadTreeNode node = this.GetTree(this.DataSource[expandedNodeID]);
			if(node.Nodes.Count > 0)
			{
				foreach(RadTreeNode child in node.Nodes)
				{
					e.NodeClicked.AddNode(child);
				}
			}
			e.NodeClicked.ExpandMode = ExpandMode.ClientSide;

I have found the issue is caused by not having a height property set to the RadTreeView.

I have tried the below code but this is failing to apply the Height property to the RadTreeView. I am wanting to apply the height property to the RadTreeView based on the height of the RadWindow as a user will likely resize this window and having a static height would make the tree cut off after the desired height.

window.setTimeout(ResizeRadTree(), 100);
 
	function ResizeRadTree()
	{
		$('cRadTreeView').height(GetRadWindow().Height)
	}

Hello Jonathan,

You can refer to this forum post - Make RadTreeView occupy 100% of the Window height.

Hope this will help.
