1. It is sometimes required to make UserControls communicate between each other. So the following demo is used to show the same.
2. Even though there are advantages in communicating the Usercontrols, in some cases it increases the dependency between them which can hinder the robustness of the page.

Data Transfer between two ASP.NET Pages
RamiVemula on March 15, 2010 at 11:53 am
In most of the present day Web Applications, it is required to transfer data from one web page to another web page. Requirements like maintaining user preferences across the application, identifying user between transactions, correlating data based on previous page options etc, always drive programmers to write code to transfer data from page to page.
There are numerous ways in accomplishing the above said tasks, selecting an appropriate way for an appropriate situation is vested in the hands of programmer. Some of the most prominent techniques, out of my knowledge are listed in this article. Read More…

For example when the screen resolution of the client’s web browser is needed to be known in code-behind, then the simple way to accomplish is to access JavaScript variable in Code-Behind.Read More…

Enumerating, Managing and Monitoring File system using C#
RamiVemula on January 6, 2010 at 7:15 pm
Applications often need to read and write data to the disk, sometimes for the sake of user and most of the times for its internal use. To do this task we need to review the present file system of the disk and then manage the resources according to our requirements. In some applications, it is required to monitor any changes made to the file system and notify them accordingly.
Although there are number of articles written on the web about this topic, still I want to go with this topic in detailed for one more time. The main aim of this article is to understand the file system and manage it through some inbuilt C# classes. The article is written keeping beginners in mind.Read More…
