Hy!
I filled a GridView with some data from a table(obtained from a DataBase).
Now i have to delete some row, but i have to do this without deleting that information from the DataBase. It would be easy to use DataBase. I would obtain that table and fill that GridView again on the pageLoad, but i'm not aloud.
I really didn't find how to do this.
Please someone help! If this is possible.

How are you binding the data to the GridView? Are you using a DataTableAdapter or some other object? A DataTable or DataSet are in-memory representations of the data, so unless you are calling a method to delete the row directly in the database, you should only be working with a temporary copy of the data.

I'm doing like this:
gridView.DataSource = table;
gridView.DataBind();
"table" is the table that i get from an SQL query. This piece of code, is integrated in a fillGridView function that i have, but i suppose this is what you are interested in.

And what is table? I'll assume it is a DataTable, in which case it is, once again, an in-memory representation of the data, not connected to the database from which you obtained it.

I'm filling this gridView on the form's load. Now, every time i delete a row i redirect to the same page, i get the table from the database and fill the grid. Because i don't modify the database the table will always be the same. Supposing i fill it with a DataSet, which i modify every time i press delete, how do you suggest kipping that DataSet? It works if i use Session variables? I can't try it cause i don't have the code right now?

First don't delete rows one at a time, use a checkbox column to allow the users to select which rows to delete, then do it all at once. Or, yes cache the data, then update the database when completed. This isn't an unknown problem, there are a wide variety of articles on the subject.

Probably the way i'm doing the fill now is putting me in a serious problem cause i'm not aloud to modify the database. First, it was made following this idea.
How should i proceed now?
Filling a dataset from a table then filling the GridView with a dataset?
Then I activate that delete button and so on?
I'll show you exactly the fillGridView function i have over 2 days.

Allowed != aloud
I don't need to see the code. Once you fill the dataset via your database query, the data has become disconnected from the database. I've told you this several times now.

Yes indeed!
I've tried to much to adapt the code i had.
I'll change the approach.
Thanks!

I'm trying to read an Excel file into my ASP.NET page; not just the entire file, but individual cells. I'm having lots of trouble, I've been looking online at example of reading in an entire Excel file, and I can't even do that. I'm having problems.

Can you be more specific with what 'problems' you are having? Maybe some sample code...

I have an ASP.NET program that reads in a text file, then does stuff with it. What I would really like to do is allow the user to right-click on their text file, click "Send To", and then send it to my program on the list.
(I know how to add my program to the "Send To" list, just type in "sendto" in the run command)
My problem is that I have the text file, and I have the program in the "Send To" option; how do I make them compatible so that the program will read in the text file being sent?

Hello Friends..............
I am using AjAX Control Toolkit Tools in my web application.
Such as Calender Extender, Rounded corner and Masked edit......
But I am afraid that these tools may create problem during deployment..........
Please tell me that these controls are reliable or not.........
Thanks

OK, yes they are reliable*. Does it make you feel any better?
What is your concern? What deployment problems?

Is it better to cache a dataset on the webserver OR
use a XML file on a server and maintaining a structure in the XML file that we populate accordingly when required
The dataset has 10 datatables and the site could have more than 50 users at once instance
Is it better to use the XML file stored on a server or Cache the dataset on the webserver considering that the application runs on a web farm
I have to cache the dataset for the users to come back again to the same page and enter new values in the dataset ( something like adding stuff to a basket )
Thanks

Don't you have a database that you can use for this? It's more stable and much more scalable, which is important for a high load application.
Despite everything, the person most likely to be fooling you next is yourself.
