Answer 1

写DeleteCart的处理方法了吗,
帖出来看下

Answer 2

<input type="button" runat="server" value='Delete'  id="Cart" >我将这个按钮单独放在外面可以删除的
Public Sub DeleteCart()
        m_Orders.Clear()
End Sub

Answer 3

你应该给按钮定义个CommandName,如CommandName = "del",
在datalist中
<asp:datalist id="ShoppingCartList" runat="server" DataKeyField="Name" OnItemCommand="DataListCommand">在后台写
public void DataListCommand(object sender,System.Web.UI.WebControls.DataListCommandEventArgs e)
{
    if(e.CommandName = "del")
    {
       m_Orders.Clear()    }
}我这个是C#的,看得懂吧,

        Dim ds As DataSet = New DataSet        da.Fill(ds, "products")
        DataList1.DataSource = ds.Tables("products")
        DataList1.DataBind()
