Is there a way to select certain rows and for each row, perform a function? Specifically, I want to select specific rows and then send them an email.
Here's a breakdown:
1. Select * from STUDENTS where status = active
2. For each row that is returned, take the $email column and email the student message
3. Repeat until all qualifying rows have been completed.
I have a ListView with Checkbox. My requirement is - When I click on any checkbox then it should return all the columns values of that row on behalf of that CheckBox. After much study I came to know that using DataTable and DataRow I can get all data of particular ID of a Row. But I am unable to work with this. My code is something like below:
DataTable dt=new DataTable();
dt=objBAL.Get_ShoppingCartData();
ListView1.DataSource=dt.Tables[0];

Without giving away specifics: basically, I have a bunch of users adding content to my site. What happens now is ajax sends the text to a web service which does its thing, sends the info to the DB, Sends the user an e-mail, and then returns a response to the browser to do something.
What I would like to do is change that order. I want to return a response to the browser so the user is not waiting on the e-mail to send before they get their response. Basically, I'm trying to gain every milisecond I can to quicken the response, and there's no reason for the user to wait for the server to send their e-mail before it tells them that everything worked ok. If the info went to the DB, that's all the user needs to know, they'll know the e-mail sent when it shows up in their inbox. I notice this is an issue on my local machine which has no SMTP server and can actually hang the page response up for a few extra seconds because it's throwing errors trying to send something with no SMTP server.
So, I know in my function when I say
[Code]....
it WORKS, but I want to send the e-mail after the return. Is there ANY way to get this to happen?

View 1 RepliesI have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?

View 1 RepliesI have a gridview which right now is getting loaded with four pages of data. There are 50 rows per page. My problem is I need the "select all" button on my page to select 180 rows, not just the 50 on the page. This is my javascript:
Code:
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
for (var i = 0; i < frm.elements.length; i++) {
var e = frm.elements[i];
if (e.type == 'checkbox' && e.name.indexOf("ckSelected") > -1)
e.checked = isSelected;
}
}
I am more a C# person than javascript, but I am deducing that I need something other than document.forms[0] to represent the entire gridview. Or perhaps, I can't do this in javascript at all. Do I need server code to run and set a session variable, then when the user clicks the button to do something with all his selected rows (it goes to a detail page), query that session variable to see if it's all rows instead of iterating through each gridview row individually to see if the checkbox is checked?
I'm looking to write some script that checks that: The current user of whom is logged in has the correct authority credentials. NB: Script in C# before I continue. To give a bit more background. The SQL DB Table for AdminUsers has a field 'Authority' this is linked to another table (Authority) which has the values/different levels of authority in them. Thus, if aN admin user whose Authority level is just listed as 'user', for example, in the database and wants to edit information that requires 'Supeuser' authority level - it cannot be performed and is redirected to another page. In detail, my particular page, the operation is being done via a ASP Button within a ASP Repeater. Of each record that occurs there is the button that, once pressed, updates the field in the database (in this case for a Guestbook table which has a 'Moderated' field of 'bit/bool' data type, changing it from false to true (or 0/1)). To allow that entry to be displayed on the front-end for public viewing. All this can onyl happen on the basis of, as previously stated, their authority is of the appropriate level. Here is what my attempt was. The outcome of which simply redirects to the 'Unauthorised' page, despite the user logged in having the correct authority credentials.
