If you don't specify the action attribute, it will be ignored as the form is always submitted to the page itself. If method attribute is left out, by default it will be set to method="post". Other attributes like name and if are also automatically assigned by ASP.NET if you don't mention them. Important point to keep in mind here is that an .aspx page can have only one
The most important thing to store in the web.config file is the database connection string. The reason of storing connection string in the web.config file makes sense since if later we ever want to change the location of our database we just have to change the connection string in the web.config file and thats it. This will certainly save us a lot of alteration in different files where we used the old connection.
In this article I am going to look at how to upload a file to the web server and compress it using the compression methods provided in .Net. I will use the open source compression method to compress to a .gz file. The method is available in System.IO.Compression.
language called C#. C# is a simple, modern, object oriented, and type-safe programming language derived from C and C++. C# (pronounced ?C sharp?) is firmly planted in the C and C++ family tree of languages, and will immediately be familiar to C and C++ programmers. C# aims to combine the high productivity of Visual Basic and the raw power of C++.C# is a strongly-typed object-oriented language designed to give the optimum blend of simplicity, expressiveness, and performance.
Let's also review the application environment. A typical user analysis model would consist of around a 100 of these data entry pages. The Web site itself supports an unlimited number of analysis models. Thus, the database is quite large and the process of obtaining the meta data is quite complex. Running more queries than absolutely necessary can be a real drag on performance. Also keep in mind that a typical user will spend anywhere from 15 - 45 minutes on a single data entry page completing that section of the analysis model.
Normally, I would be reluctant to implement a solution that loads up the ViewState in this manner. Our web farm environment pretty much ruled out the use of static objects or the application cache. The performance impact of having larger than normal ViewState and the process of managing ViewState isn't necessarily prohibitive. That said, if you are trying to squeeze out every once of performance, doing this without it being necessary could hurt your cause.
You can use my sample as a means to measure how much is being stored in ViewState for the amount of data you expect to have in your own application. The default setting of 60 textboxes and 60 dropdown lists (each list contains 10 records) takes up roughly 100KB of html and ViewState combined
