Question

How can i select certain columns from a stored procedure, lets say i just want 2 of the 10 columns
item and total sales.

 Dim reader As SqlDataReader
            cmd.Parameters.AddWithValue("@yeartoget", DropDownList1.SelectedValue)
            If RadioButtonList1.SelectedIndex = "0" Then
                cmd.CommandText = "asofsales"
            ElseIf RadioButtonList1.SelectedIndex = "1" Then
                cmd.CommandText = "asofnetsales"
            End If

            cmd.CommandType = CommandType.StoredProcedure
            cmd.Connection = conn
            conn.Open()
            reader = cmd.ExecuteReader()
            GridView1.DataSource = reader
            GridView1.DataBind()
            conn.Close()

Just specify the columns you want and turn off the autogeneration.

<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="False" >
        <Columns>
            <asp:BoundField DataField="field1" HeaderText="First field to show"  />
            <asp:BoundField DataField="field2" HeaderText="Second field to show"  />

You could also read the results into a datatable and delete the columns you don’t want or do it with linq but that’s just overkill unless you need to fiddle with the data further before displaying it
