Header Template

[Jim Heavey]

Hello, I am trying to figure out how to use the <HeaderTemplate>. I had
a datagrid working fully. Then I wanted to put a checkbox in one of the
header columns. When I added the <HeaderTemplate> everything starts
highlighting. I am following this example I found on a web site which
show it as follows:

<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<b>My Header Text</b>
</HeaderTemplate>
<asp:BoundColumn datafield="Company"></asp:boundColumn>
</asp:TemplateColumn>
</Column>

<HeaderTemplate> highlights
<columns> highlights and all of the <style> related items highlight
(SelectedItemStyle, ItemStyle...)

Can you point me in the direction as to what I am doing wrong?

Thanks in advance for your assistance.
