Hi all I have the following gridview in my aspx page

 <asp:GridView ID="GridView1" runat="server">
        <Columns>
        <asp:BoundField DataField="RName" HeaderText="Row Number" />
        <asp:BoundField DataField="RContact" HeaderText="Row Number" />
        <asp:BoundField DataField="RPostalCode" HeaderText="Row Number" />
        <asp:BoundField DataField="RAddress" HeaderText="Row Number" />
        <asp:BoundField DataField="RUnitNo" HeaderText="Row Number" />
        <asp:BoundField DataField="Size" HeaderText="Row Number" />
        <asp:BoundField DataField="Weight" HeaderText="Row Number" />
        <asp:BoundField DataField="Price" HeaderText="Row Number" />

        <asp:TemplateField HeaderText="Action">
            <ItemTemplate>
                <asp:Button ID="Button1" runat="server" Text="Button" />
            </ItemTemplate>
        </asp:TemplateField>
        </Columns>
        </asp:GridView>


I have the following datatable that bind to it in the code behind

Dim dt As New DataTable()

        dt.Columns.Add(New DataColumn("RName", GetType(String)))
        dt.Columns.Add(New DataColumn("RContact", GetType(String)))
        dt.Columns.Add(New DataColumn("RPostalCode", GetType(String)))
        dt.Columns.Add(New DataColumn("RAddress", GetType(String)))
        dt.Columns.Add(New DataColumn("RUnitNo", GetType(String)))
        dt.Columns.Add(New DataColumn("Size", GetType(String)))
        dt.Columns.Add(New DataColumn("Weight", GetType(String)))
        dt.Columns.Add(New DataColumn("Price", GetType(String)))
     
        Dim dr As DataRow = dt.NewRow()

        dr("RName") = txtRecipientName.Text
        dr("RContact") = txtRecipientContact.Text
        dr("RPostalCode") = txtRecipientPostalCode.Text
        dr("RAddress") = txtRecipientAddress.Text
        dr("RUnitNo") = txtRecipientUnitNo.Text
        dr("Size") = txtSize.Text
        dr("Weight") = txtWeight.Text
        dr("Price") = MainModule.CalculateRate(txtWeight.Text, txtSize.Text)
        dt.Rows.Add(dr)
     

        GridView1.Visible = True

        GridView1.DataSource = dt

        GridView1.DataBind()


The problem is that my gridview will have duplicate column and data e.g
