Sometimes Page load event not firing in asp.net

           , , , , , , , , ,      No comments   


The reason for the page executing doesn't affect the page cycle, the Load event always fires when the page is executed.

So, if the Page_Load doesn't run sometimes, it's because the page is cached and doesn't execute on the server. The page can be cached in the browser, in a router somewhere along the way, or on the server using server side page caching.

If you haven't enabled server side page caching for the page, it's cached in the browser or in the network. You can use cache settings to try to elliminate this:

Response.Cache.SetCacheability(HttpCacheability.NoCache);

This will keep the page from being cached in normal circumstances. (Check also that your browser isn't in offline mode, then it will use anything in the cache regardless of it's cacheability settings.)

2) On Class File (.CS) Page
String Path = HttpContext.Current.Server.MapPath("/");

3) If you are using Thread and want to get physical path in .CS or .asax file
String Path = HttpContext.AppDomainAppPath.Replace("//","\\");

Use .VB and .CS class file in one website using asp.net

           , , , , , , ,      No comments   

When I was creating my one of the site, I chose to write it in C#. I had a problem with the App_Code folder because I had some code in VB.NET code and some C# code I needed to put in there. I didn't want to rewrite my VB.NET code in the App_Code folder just so I could write the rest of the code for the site in C#.

Luckily, the ASP.NET Team had already thought about just this kind of circumstance. They implemented a way to partition the App_Code folder into sub-folders, one for each set of code files written in the same programming language. Awesome, I didn't have to spend a couple hours converting code from VB.NET to C#!

The below works with ASP.NET 2.0 and later.

Even if you don't use multiple different programming languages for your code files in the App_Code folder, you could use this feature to organize your sets of related code files into sub-folders.

Step 1: Add the following lines to the web.config


<configuration>
<system.web>
<compilation>
<codeSubDirectories>
<add directoryName="VB_Code"/>
<add directoryName="CS_Code"/>
codeSubDirectories>
compilation>
system.web>
configuration>

Step 2: Create a sub-folder in the App_Code folder for each language you want to support.
For Example:
/App_Code/VB_Code
/App_Code/CS_Code

Step 3: Place your VB.NET code in the VB_Code folder and place C# code in the CS_Code folder.
