    Hi
    i have a big problem with RadTreeView (version 2010.2.929.35).
    The display of nodes is correct with Internet Explorer 8 and above but instead with Internet Explorer 7 when you hover the mouse over the node, the node it disappears!.
    For testing i define OnClientMouseOver events:

    <telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" TriStateCheckBoxes="false"
    CheckChildNodes="true" Width="170px" style="white-space:normal;" OnClientMouseOver="onMouseOver">
                                <DataBindings>
                                    <telerik:RadTreeNodeBinding Expanded="False" />
                                </DataBindings>
                        </telerik:RadTreeView>
     and

    function onMouseOver(sender, e)
    {
            var node = e.get_node(); 
            node.onmouseover = null;
    }

    the result is that in Internet Explorer 8 and above the hover is properly disabled but in Internet Explorer 7, the node continues to disappear.
    Can someone help me? Thank you very much.

    Hi Marco,

    Indeed it might be an issue with the 2010.2.929.35 version of our controls. Please try upgrading to the latest version and check if it still persists.

    Hi Kate
    i solved my problem setting the height attribute of control.
    See this attibute in bold style

    <telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" TriStateCheckBoxes="false"
    CheckChildNodes="true" Width="170px" Height="290px" style="white-space:normal;" OnClientMouseOver="onMouseOver">
    <DataBindings>
    <telerik:RadTreeNodeBinding Expanded="False" />
    </DataBindings>
    </telerik:RadTreeView>

    With version 2012.3.1205.35 the control's behavior is worse!
    Thk
