Unable to cast object of type 'System.Int32' to type 'System.Web.UI.WebControls.DataKey'

hi ,

i have a datalist with an itemtemplate section that contains an image and a delete button to delete the corresponding image .

<asp:DataList ID="DataList1" CellSpacing="25" runat="server" DataSourceID="sqldatasource3" DataKeyField="ID" repeatColumns="4" repeatdirection="Horizontal" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="0px" CellPadding="3" >

<ItemTemplate>

<table border="0" cellpadding="0" cellspacing="0" >

<tr>

<a href='<%# DataBinder.Eval(Container.DataItem, "image", "ImageViewer.aspx?id={0}") %>' >

<img alt="sub location image" src='<%# DataBinder.Eval(Container.DataItem, "image", "casterthumbnails/{0}") %>' >

</a>

</tr>

</table>

<p class="imagenumber"><%# Server.HtmlEncode(Eval("id").ToString()) %> </p>

<div align="right">

<asp:ImageButton ID="imgb1" OnClick="delPicture" runat="server" ImageUrl="~/image/delete.jpg" ToolTip="Delete" />

</div>

</ItemTemplate>

</asp:DataList>

Sub delPicture(ByVal sender As Object, ByVal args As System.Web.UI.ImageClickEventArgs)

Dim iteml As DataListItem = CType(CType(sender, Control).NamingContainer, DataListItem)

If Not (iteml Is Nothing) Then

      Dim pos As Integer = iteml.ItemIndex

      Dim keys As DataKey = DataList1.DataKeys(pos)

      ' code used to delete the picture

End If

End Sub

When i click on the delete button the following error occured :

Unable to cast object of type 'System.Int32' to type 'System.Web.UI.WebControls.DataKey'

Line 80:         If Not (iteml Is Nothing) Then
Line 81:             Dim pos As Integer = iteml.ItemIndex
Line 82:             Dim keys As DataKey = DataList1.DataKeys(pos)
Line 83:             ' code used to delete the picture
Line 84:         End If
