Ich habe eine Shopping-Seiten, aber habe Probleme mit der Menge, ich weiß nicht, wie Sie den Wert der Textbox auswählen, das ist mein Code.Warenkorb asp.net C#
<table class="table table-condensed">
\t \t \t \t \t <thead>
\t \t \t \t \t \t <tr class="cart_menu">
\t \t \t \t \t \t \t <td class="image">Product</td>

\t \t \t \t \t \t \t <td class="description"></td>
\t \t \t \t \t \t \t <td class="price">Price</td>

\t \t \t \t \t \t \t <td><div class="col-md-1"></div></td>
\t \t \t \t \t \t </tr>
\t \t \t \t \t </thead>
\t \t \t \t \t <tbody>
<!-- begin Cart -->
<% for(int j=0;j<NoItems;j++)
{
Label8.Text = j.ToString();
view();%>
\t \t \t \t \t \t <tr>
<td style="display:block">

\t \t \t \t \t \t \t <td class="cart_product">

\t \t \t \t \t \t </tr>
<% i++;
} %>
<!-- end -->
\t \t \t \t \t </tbody>
\t \t \t \t </table>
now in the behind code have this
public string[,] Carrito = new string[20, 13];
NoItems = Convert.ToInt32(Session["NoItems"]);//its the number of differents items
Carrito = (String[,])Session["Cart"];//its a array with all products
public void view()
{
Label1.Text = (String)Carrito[i, 1] + "/" + (String)Carrito[i, 3] + "/" + (String)Carrito[i, 4] + "/" + (String)Carrito[i, 5] + "/" + (String)Carrito[i, 6] + "/" +
(String)Carrito[i, 7] + "/" + (String)Carrito[i, 8] + "/" + (String)Carrito[i, 9] + "/" + (String)Carrito[i, 10];
Label2.Text = "$" + (String)Carrito[i, 2];
Label3.Text = "$" + (String)Carrito[i, 2];
Cantidad.Text = (String)Carrito[i, 13];
}
public void comprar(object sender, EventArgs e)
{
for (int a = 0; a < NoItems; a++)
{
}
}jetzt seine mein Problem, wie man die Menge des Produkts zu speichern,
jetzt nicht, dass ich eine Datenbank verwenden, alle Informationen, seine in Sessions, die Datenbank ist in Fortschritt.
irgendwelche Ideen? Entschuldigung, mein Englisch.
