How to insert a column in a gridview after the auto generated columns - ASP.NET

This is my gridview:

<asp:GridView ID="gridview" runat="server" AutoGenerateColumns="true">
    <Columns>
        <asp:TemplateField HeaderText="TestColumn">
            <ItemTemplate>
                <asp:LinkButton ID="lkbtn" runat="server" Text="Edit"
                    CommandName="Update" CausesValidation="False" ToolTip="Edit" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

The TestColumn ends up being the first column, but i want it after the auto generated ones.
