Hi all,
I have a simple page on which I've place a gridview which is bound to a generic List that contains ShoppingCartItem objects.
the code for my aspx file looks like this:
]]>
<asp:content id="Content3" contentplaceholderid="ArticleContent" runat="server" xmlns:asp="#unknown">
<asp:label id="lblShoppingCartStatus" runat="server" text="">
<asp:gridview onrowediting="gridCart_RowEditing">
OnRowCancelingEdit="gridCart_RowCancelingEdit"
OnRowUpdating="gridCart_RowUpdating"
OnRowCommand="OnRowCommand"
OnRowUpdated="gridCart_RowUpdated"
ID="gridCart" runat="server"
AutoGenerateColumns="false" EnableViewState="true">
<columns> <asp:boundfield readonly="true" datafield="Description" headertext="Product">
HtmlEncode="False">
<itemstyle width="300px">
<asp:boundfield readonly="true" datafield="Price" headertext="Price">
HtmlEncode="False">
<itemstyle width="100px">
<asp:boundfield readonly="false" datafield="Quantity" headertext="Quantity">
HtmlEncode="False">
<itemstyle width="100px">
<asp:commandfield buttontype="Link" edittext="Modify" showeditbutton="true" causesvalidation="false">
My code behind code looks like this:
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections;
namespace Customer
{
public partial class PrimeShopCheckout : System.Web.UI.Page
{
private List<shoppingcartitem> ShoppingCartItems
{
get
{
if (ViewState["shoppingCartItems"] != null)
{
return (List<shoppingcartitem>)ViewState["shoppingCartItems"];
}
return new List<shoppingcartitem>();
}
set
{
ViewState["shoppingCartItems"] = value;
}
}
private void BindGrid()
{
gridCart.DataSource = ShoppingCartItems;
gridCart.DataBind();
}
protected void gridCart_RowEditing(object sender, GridViewEditEventArgs e)
{
gridCart.EditIndex = e.NewEditIndex;
BindGrid();
}
protected void gridCart_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gridCart.EditIndex = -1;
BindGrid();
}
protected void gridCart_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
// get the information
int rowIndex = e.RowIndex;
var a = gridCart.Rows.Count;
}
protected void gridCart_RowUpdated(object sender, GridViewUpdatedEventArgs e)
{
e.KeepInEditMode = false;
}
protected void OnRowCommand(object sender, GridViewCommandEventArgs e)
{
var aaa = gridCart.Rows.Count;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Hashtable shoppingCart = (Hashtable)WebProfile.Current.ShoppingCart;
List<shoppingcartitem> shoppingCartItems = new List<shoppingcartitem>();
IDictionaryEnumerator enumerator = shoppingCart.GetEnumerator();
while (enumerator.MoveNext())
{
var item = new ShoppingCartItem();
Product product = (Product)enumerator.Key;
int quantity = (int)enumerator.Value;
item.Description = product.Description;
item.Price = product.Price;
item.Quantity = quantity;
shoppingCartItems.Add(item);
}
ShoppingCartItems = shoppingCartItems;
gridCart.DataSource = ShoppingCartItems;
gridCart.DataBind();
}
}
}
[Serializable]
public class ShoppingCartItem
{
public string Description { get; set; }
public decimal Price { get; set; }
public int Quantity { get; set; }
}
}
The problem is that when I click the Update button to change the number of items for a specific product, in the RowUpdating event handler I get the number of rows as 0!!!!
I've read plenty of docs on the gridview, searched google for answers to my problem, saw implementations for the functionality I use .... according to what I read so far, everything should work fine. But it's not!
Can anyone let me know why the number of rows is zero in the row updating event?
Where am I losing the data in the gridview?
I need help with this as I am completly stuck at this moment - I don't have any clue what else to try....
Thanks in advance!

Try checking the referrer. Request.UrlReferrer. Make sure you check for NULL before using it.

You need to stick this in the SQL forum, but you might want to look at the fact that you are declaring a global cursor within a procedure that you recursively call from within the cursor...

Hi
I want to know a way by which i can create a .txt file in another system having username and password connecting through a path
Eg:"ftp//68.288.132.109/UserName/Password"
|
|
|
|
|
As you have IP/Username/Pwd, WMI should allow u to connect to remote computer and create files in it. So google your problem with WMI in the search query and u should be able to get some code snippets

You can't. ASP.NET is not built for that.

Create an object of the class file in aspx file and then you can access the variables. You can also access it using properties.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.
