I'm using a try catch block for all the functions in my data access layer, and if there is an error, i want to redirect the user to my custom error page, but my data access layer consists of classes and not forms, and the classes don't recognize the response.redirect, or server.transfer methods. How can I transfer them to the error page from these classes?

Thanks in advance,

You should not do this. The Data Access layer should be agnostic to whether you are creating a Windows Forms, ASP.NET, or console application. You should throw the exception higher, at least up into your busines layer.

If you insist, however, you get get a handle on the current Response object like this:

    System.Web.HttpContext.Current.Response.Redirect( "~/error.aspx", true )
 
Be sure to include the second argument (true) if you are using this command inside a Catch block.

Hello !

From your data access layer, you should return an error code, or, better, throw an (specialized - inherited) exception to the calling layer. This lets you the choice of the proper reaction to your presentation layer or your controller.
Furthermore, for unhandled exceptions, there is a way to catch them in a single event handle located in the global.asax file (see the .NET documentation for more details).

Hope it helps

You can do one thing. Remove try catch from your data access layer and apply it to the calling level of that data access layer.
For example you can write below in WEB application

MyDataClass objData=new MyDataClass();
try
{
objData.execute();
}catch(Exeption e)
{
}
