As on this page when you try to leave without submitting you are given a warning. I no this is done on pageunload with javascript but I'm pretty sure there is a tutorial on this somewhere but I'm having trouble finding it.
Anyone know off hand where a tutorial is to warn the user when they are trying to leave a page.
I didn't get any requirements for the signature

Nevermind, I figured it out by viewing the source on this page.
Thanks Code Project!

Hi friends,
How should i add rich text box control in web applications?
Thanks in advance
Regards,
Venkat

if by rich text box you mean an editor, then check out FCKeditor - http://www.fckeditor.net/[^]
it has a component for ASP.NET so it's quite simple to use it and plus it is very powerful.

It should not be the subject.  Always try to give proper subject that every body can understand your main query objective from Subject itself.

You actually have several serious problems.
1. You posted the same question twice within a very short time
2. Your subject is meaningless
3. It appears the shift and various other keys don't work on your keyboard. There is no additional charge per character here on CP, so PLZ USE ALL UR KEYS pROPErly

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.
