Hi,

I'm trying to use the RadTreeView with fixed width and with overflow: auto. In IE9 after the horizontal scrollbar has appeared if you hover with mouse over any node the TreeView enlarges (mean it's higher). This happend every time, so the TreeView is higher and higher. Here is a sample code:

aspx:

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="rsmMain" runat="server" EnablePageMethods="true" EnableScriptGlobalization="true" EnablePartialRendering="true"/>

<telerik:RadTreeView ID="rtvTree" runat="server" style="width: 150px; overflow: auto; border: 1px solid black;" />

</form>

</body>

</html>

code behind:

protected void Page_Load(object sender, EventArgs e) {

rtvTree.Nodes.AddRange(new List<RadTreeNode>() { new RadTreeNode("test Node 01", "1"), new RadTreeNode("test Node 02", "2") });

rtvTree.Nodes[0].Nodes.AddRange(new List<RadTreeNode>() { new RadTreeNode("test Node 01 - 01", "3"), new RadTreeNode("test Node 01 - 02", "4") });

rtvTree.Nodes[0].Nodes[0].Nodes.AddRange(new List<RadTreeNode>() { new RadTreeNode("test Node 01 - 01 - 01", "5"), new RadTreeNode("test Node 01 - 01 - 02", "6") });

}

If you'll expand all nodes, horizontal scroll bar will appear.
Please let me know whether I miss something important or whether is there some work-around.

Thanks,

Petr Kotal.

Hello, David.

The fix for this is rather odd -- just add max-height: 100% to the containing div.

As per the attached project.

All the best,
