GridView column expanding

[tshad]

I have a GridView that I want to control all the columns widths except for
1.

Most of them seem to work that way except for this one:

<asp:TemplateField ItemStyle-CssClass="alignRight"
SortExpression="GiftAmount" HeaderStyle-Width="100px" HeaderText="Gift">
<ItemTemplate>
<asp:Label ID="lblGiftAmount" runat="server"
SortExpression="GiftAmount" Width="100px" Text='<%#
Eval("GiftAmount","{0:c}") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtGiftAmount" runat="server" Width="100px" Text='<%#
Eval("GiftAmount","{0:###,###.00}") %>' />
</EditItemTemplate>
</asp:TemplateField>

I have the Header, Item and Textbox are all set to 100px.

The Grid is set to 100%.

As I expand the grid, this column expands as well. I have another column
that has no size.

Shouldn't that be the only one that expands?

How do I get this column not to expand?

Thanks,

Tom
