Gridview SortExpression

Hi Experts,

I have a column in the gridview which gets its value in Rowdatabound. How can I sort that column. How to specify the SortExpression in this case.

<asp:TemplateField HeaderText="Vendor1" SortExpression="??">
                    <HeaderStyle Width="20px" HorizontalAlign="left"/>
                    <ItemStyle Width="20px" HorizontalAlign="left"/>
                        <asp:Label ID="lblVendor1ID" runat="server" Visible="false" ></asp:Label>
                        <asp:Label ID="lblVendor1Name" runat="server"></asp:Label>

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Option 1: Just sort by one of your columns.
<asp:TemplateField HeaderText="Vendor1" SortExpression="Vendor1Name">
   <ItemTemplate>........ </ItemTemplate>

Open in new window

Note HeaderText and not HeaderTemplate
Option 2: Manual Sort with the Sort Command
                <asp:LinkButton ID="LinkButtonVendor1" runat="server" Text="Vendor1" CommandName="Sort" CommandArgument="Vendors">

Open in new window

Then you handle the custom sort through code. See this geek:
