GridView is making two of each column

I have a GridView control with three columns, all BoundField columns. They
all have a HeaderText and DataField property set, and the third one has a
DataFormatString property as well. When I run my code, the GridView displays
two sets of columns. The first set looks exactly as I would expect. The
second set, which should not be there anyway, uses the DataField as the
header and does not apply the DataFormatString for the third column. What is
going on here? Here is my GridView control:

<asp:GridView ID="grdGifts" runat="server" PageSize="15"
PagerSettings-Mode="NextPrevious" PagerSettings-NextPageText="Next 15
Products" PagerSettings-Position="Bottom"
PagerSettings-PreviousPageText="Previous 15 Products"
EnableSortingAndPagingCallbacks="true" AllowPaging="true"
AllowSorting="true">
<Columns>
<asp:BoundField HeaderText="Products" DataField="prodname"/>
<asp:BoundField HeaderText="Brand" DataField="brandname"/>
<asp:BoundField HeaderText="Action" DataField="prodid"
DataFormatString="[&nbsp;<a
href='edit_product.asp?prodid={0}'>Edit</a>&nbsp;/&nbsp;<a
href='delete_product.asp?prodid={0}'>Delete</a>&nbsp;]"/>
</Columns>
</asp:GridView>

The Load event for the GridView is as follows:

Private Sub grdGifts_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles grdGifts.Load
Dim myconnection As New
SqlConnection(System.Configuration.ConfigurationMa nager.AppSettings("connectionstring"))
Dim gifts As New DataTable
Dim giftadapter As New SqlDataAdapter("SELECT
products.prodname,brands.brandname,products.prodid FROM products INNER JOIN
brands ON prodbrand=brandid", myconnection)
giftadapter.Fill(gifts)
Me.grdGifts.DataSource = gifts
Me.grdGifts.DataBind()
End Sub

If anybody has any idea why this is happening, I would appreciate the help.
Thanks.

My sorting also isn't working. I looked at the generated code, and it looks
correct. Here is the code for my GridView and the databinding:

<asp:GridView ID="grdGifts" runat="server" PageSize="15"
PagerSettings-Mode="NextPrevious" PagerSettings-NextPageText="Next 15
Products" PagerSettings-Position="Bottom"
PagerSettings-PreviousPageText="Previous 15 Products"
EnableSortingAndPagingCallbacks="true" AllowPaging="true"
AllowSorting="true" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Products" DataField="prodname"
SortExpression="products.prodname"/>
<asp:BoundField HeaderText="Brand" DataField="brandname"
SortExpression="brands.brandname"/>
<asp:BoundField HeaderText="Action" DataField="prodid"
DataFormatString="[&nbsp;<a
href='edit_product.asp?prodid={0}'>Edit</a>&nbsp;/&nbsp;<a
href='delete_product.asp?prodid={0}'>Delete</a>&nbsp;]"/>
</Columns>
</asp:GridView>

Private Sub grdGifts_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles grdGifts.Load
Dim myconnection As New
SqlConnection(System.Configuration.ConfigurationMa nager.AppSettings("connectionstring"))
Dim gifts As New DataTable
Dim giftadapter As New SqlDataAdapter("SELECT
products.prodname,brands.brandname,products.prodid FROM products INNER JOIN
brands ON products.prodbrand=brands.brandid", myconnection)
giftadapter.Fill(gifts)
Me.grdGifts.DataSource = gifts
Me.grdGifts.DataBind()
End Sub

Am I also forgetting some simple little thing for the sorting? I have the
AllowSorting="true" and the SortExpression property for the columns that I
need to be sortable. Is there something else I need? Thanks.

Code in Page_Load would need to be inside If Not Page.IsPostBack Then check
so that it won't prevent postback events (such as Sorting event) from
working.
