ItemCommand event doesn't fire with the Repeater control

I am building a website whereby people, before checking out of the shopping cart (and transferring to the payment iframe) can select which items f开发者_StackOverflowrom the shopping cart list to delete. The results from the shopping card are listed in a Repeater control. There is a Button in the Repeater which deletes a record from the database (used LINQ to SQL to do that.)

THe problem is that the ItemCommand event doesn't fire when i click the button. I tried 'response.write(test)' and it still would not work. It is as if the repeater cannot interact with the commands. It does render the results tho.

I would really appreciate if you could help me as I'm approaching a deadline and I've exhausted all the resources on the internet before turning to you guys!

Here's the code:

<asp:Repeater ID="RepeaterKoshnichka" runat="server" DataSourceID="LinqDataSource1">
    <ItemTemplate>
        <tr>
            <td background="images/message-bar.gif">
                <div class="message_head" style="float:left"><cite>Производ: <asp:Label ID="lblProizvod" CssClass="red_tx" Text='<%# Eval("Proizvod") %>' runat="server"></asp:Label> / Тип на Претплата: <asp:Label ID="lblPretplata" runat="server" Text='<%# Eval("Tip") %>' CssClass="red_tx"></asp:Label></cite></div>
                <div class="message_head" style="float:right"><cite>Цена: <asp:Label ID="lblCena" CssClass="red_tx" Text='<%# Eval("Cena") %>' runat="server"></asp:Label>&nbsp;
                    <asp:Button ID="Button2" CssClass="main_tx" CommandName="Delete" CommandArgument='<%# Eval("NDetID") %>' runat="server"
                        Text="Отстрани" /></cite>
                </div> 
            </td>
        </tr>
    </ItemTemplate>
</asp:Repeater>

protected void RepeaterKoshnichka_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "Delete")
    {
        if (Request.Form[e.CommandArgument.ToString()] != null)
        {
            if (Page.User.Identity.IsAuthenticated)
            {
                var nar = new DataClasses1DataContext();
                Guid detnar = new Guid(e.CommandArgument.ToString());
                var query = from c in nar.Naracka_Dets
                    where c.NDetID == detnar
                    select c;

                foreach (var c in query)
                {
                    nar.Naracka_Dets.DeleteOnSubmit(c);
                }

                nar.SubmitChanges();
                lblSuma.Text = ((Button)e.CommandSource).ToString();
            }
        }
    }
}

Your help is greatly appreciated!

You need to add the onitemcommand event handler link, i.e.

OnItemCommand="RepeaterKoshnichka_ItemCommand"

---

<asp:Button UseSubmitBehavior="False" ... />

---

One thing to note, when you are binding, make sure you are only binding if NOT post back (or after you've processed the event) otherwise you'll lose the event.

---

Is the post back happening for any other controls on your page? Do you have any javascript on your page like "javascript:void(0)" ?

I had a smimilar issue and nothing solved my problem. It ends up (after searching for a very long time) that I found that I have a textfield way higher on the page that was not validating, so I just added CausesValidation="false" to the button in the repeater and problem solved.
