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
