Hello Everybody
I am trying to develop a online order project. When customer add item then it item information will save into session data table.
Just think customer add 5 items into his/her basket when he/she click btnSubmit then i want to add all 5 items into orderDetails table using one insert statement(sometimes customer can order upto 100 iems we dont know how items customer add)
As i think
insert into tableName (itemID, Quantity, Price) values (here should be loop) and how can I add loop?
Any instruction will be really helpful

DataTable dt = (DataTable ) Session["DataTable"];
foreach(DataRow dr in dt.Rows )
{
// You can use to get record from datarow like dr["ColumnName"]
ItemId= dr["itemID"];
Quantity = dr["Quantity"]
Price = dr["Price"]
// call you function or write code for insert Record into database
}
I think this will help you.
Regards
rajesh

Check for NULL or existence of session value before casting it to escape from any exceptions.

This won't insert items in one shot.

This is not a good design. You can keep the user's items in database. When user places order, remove from this table. It would be more efficient than session.

Lop through datatable records, form insert query, don't execute it inside the loop. When loop ends, execute the query. So you will get all the records inserted.

Thanks for your reply
My database design is like this
tblOrder (orderID (PK), customerID(FK), dateStamp, totalPrice)
tblOrderDetails (orderID(FK), itemID(FK), Quantity, Price)
as you said I can create another table like tblTempOrder (orderID(FK), itemID(FK), Quantity, Price)
when customer will click btnConfirmOrder then it will add all data into tblOrderDetails
from tblTempOrder then remove all data from tblTempOrder
my question is what will happen if that customer cancel that order but he forgot to click btnCancel?
waiting for your answer
Thanks in advace

use AddMonths(-1) to subtract 1 month from a date. Fr example:
DateTime dt = DateTime.Now.AddMonths(-1);

I fail to see why the eventhandlers of a control in an asp page must be protected. If I'm trying to declare the methods private I get an 'inaccesible due to its protection level'. This means that the Web.UI.Page base class is responsible for calling the eventhandler? I never done ASP so please bear with me 
|
|
|
|

I know that Protected methods or functions whatever you'd like to call them, can only be executed by the containing class and/or any class that inherits the containing class, and (might be wrong about this part)since your aspx page does inherit from the codebehind class the event handlers and any function used on the page must be either protected or public, i would recomend protected, but if their private the inherited class cant access them, so you get that exception. Hope i helped.

Thanks, so the Inherits attribute in the aspx file defines the code behind file from where the web form inherits. Actually the code behind file stand in front of the aspx file in the inheritance tree. It's clear now

Hello all
In my application, i m generating checkbox dynamically. User can check multiple the checkbox. If user check more than three checkbox then i am showing a confirm box. Everyhting is running fine but the problem is that when user click on "Ok" ( on confirm box) at that time i am submitting the page by using following javascript code
function confApprove1()<br />
{<br />
resp =confirm ("You have checked more than 3 answers. You will be charged $250.00 for each additional answer. Do you wish to proceed?");<br />
<br />
document.Form1['JSApprResp1'].value = resp;<br />
var theform;<br />
if (resp=true){<br />
theform = document.forms["Form1"];<br />
theform.submit();<br />
}<br />
}
the page get reloaded then i am trying to find out how many check box user has checked and adding their information to database.
When i am trying to find out checked check box even though the check box is checked it shows .checked=false
and dose not go to inner loop?
how can i solve the problem.Am i doing something wrong. I have also tried to store all check box id in session and when i check value in session after user click on yes then is shown "Nothing" in session.
Thanks

You can have a postback and with a unique hidden field value that you submit, you can try to distribute the control flow from page_load to where the control goes first on submit.
