I created a repeater to list my data inside a dataTable of Session("Cart")
however i have a problem. I cannot seem to update the Quantity.
How do i code a 'btnUpdate' so that it will read the txtQuantity and update
each row of item's quantity according to the txtQuantity.Text?

<asp:Repeater id="viewCart" runat="server">
<ItemTemplate>
<tr>
<td height="15"><%# Container.DataItem("Product") %></td>
td><%# Container.DataItem("Code") %></td>
<td><%# Double.Parse(Container.DataItem("Cost")).ToString("C") %></td>
<td align="center"><asp:TextBox ID="txtQuantity" Text='<%# Container.DataItem("Quantity") %>' ToolTip="Quantity" Width="20" MaxLength="2" runat="server" /></td>
<td>Remove</td>
</tr>
</ItemTemplate>
</asp:Repeater>

Header Codes:

Dim dtCart As DataTable
Dim drCart As DataRow
dtCart = Session("Cart")
viewCart.DataSource = dtCart.DefaultView
viewCart.DataBind()

How can i delete that row too?
