Hi every1,
Could you please, some one tell me in explicit language what is ORM and what are the advantages of using it?
thx

Well,
ORM in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.
Simple details about it can be read here: WIKI ORM[^]

Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.
Advantages of ORM as as follows:
1. Facilitates implementing the Domain Model pattern.
2. Huge reduction in code.
3. Changes to the object model are made in one place.
4. Rich query capability.
5. Navigation.
6. Data loads are completely configurable allowing you to load the data appropriate for each scenario.
7. Concurrency support.
8. Cache managment.
9. Transaction management and Isolation.
10. Key Management.

You can also try following line for newline in richtextbox.
richTextBox1.Text = "Some text " + Environment.NewLine + "Again some text.";

Hello there
I have been spending almost half-a-day to get this problem solved, but could not even find a single article that would help me. I wonder whether nobody else has faced this problem.
Okay, my webpage involves creating excel files. My download button has code like this
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=clientcopy.xlsx");
HttpContext.Current.Response.TransmitFile(Server.MapPath("App_data/" + Viewstate["FileName"]));
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();
HttpContext.Current.Response.End();
Alright. this works fine. The problem is, After downloading I want to make Viewstate["FileName"] to be null. But whatever I do, during the next post back after the filetransmit, the Viewstate["FileName"] still retains the old value and refuses to get updated to null. I tried writing the Viewstate["FileName"] = null; at every possible place in the above code - at the begining, in the middle and at the end after response.end(). BUT no way
Can someone help on how to modify the viewstate after a file transmit???
Note:
=====
My webpage has an update panel. Button "GO" displays a report in the update panel based on some selections outside the updatepanel. Button "ADD" keeps on adding the displayed reports to an excelfile until Button "download" is clicked and excelfile is downloaded. "GO" and "ADD" triggers partial postback and "download" triggers fullpostback.
thanks
Kit
