    When I put a HeaderTemplate on my RadListBox it triggers an "Error: '2.offsetHeight' is null or not an object".  The form still shows but the header is very tall.  I have defined a css to get the height set correctly.

    <style type="text/css" >
        .RadListBox1 div.rlbHeader
        {
            height:25px;
        }
    </style>

    Below is the RadListBox definition

    <asp:Panel runat="server" id="pnlCustomFieldListValues" CssClass="fieldPanel" Visible="false">
        <div style="float: left; width: 750px;">
            <asp:Label ID="Label2" runat="server"
                        AssociatedControlId="radCustomFieldListValues"
                        Text="List Values:" />
            <telerik:RadListBox runat="server" ID="radCustomFieldListValues"
                                Width="100%" Height="200px"
                                SelectionMode="Single"
                                AllowReorder="true" 
                                AllowDelete="true"
                                EnableDragAndDrop="true"
                                DataValueField="Id" 
                                ButtonSettings-ReorderButtons="All" 
                                ButtonSettings-ShowDelete="true" 
                                CssClass="RadListBox1"
                                >
            <HeaderTemplate>
                <asp:Label runat="server" Width="200" Text="Name" />
                <asp:Label runat="server" Width="200" Text="Value" />
            </HeaderTemplate>
                <ItemTemplate>
                    <asp:Label 
                        runat="server" ID="lblListValueName" Width="200" 
                        Text='<%# DataBinder.Eval(Container.DataItem, "Name")%>' />
                    <asp:Label 
                        runat="server" ID="lblListValue" Width="200" 
                        Text='<%# DataBinder.Eval(Container.DataItem, "Value")%>' />
                </ItemTemplate>
            </telerik:RadListBox>
        </div>
    </asp:Panel>

    Thanks for your help,
    Dan

    I have just discovered this problem as well. And it seems to only happen when you have IE8 in compatibility mode.

    I have tested not setting the Height property and it works ok. As soon as I add it back in again the error appears.

    Hi Dan,

    Thank you for the note - the problem can be reproduced in IE8 CompatibilityMode, IE7 and IE6. I've logged it and it will be fixed as soon as possible. We're sorry for the inconvenience.

    It appears to be fixed in 2010 Q3, i'm still having an issue where its not rendereing exactly the same but i'm not able to reproduce it in a sample poject.  I haven't had much time to look at it.  Its a lot better than it was in my case nothing would show up.

    Great that this is fixed. But I'm using the controls in Sitefinity 3.7 SP4. Is there a workaround?

    Thanks,
    Daniel

    Hello Daniel,

    The work-around is not to set Height property of the listbox. We're sorry for the inconvenience.
