What is Tracing and how to enable it?

Tracing helps understand which control uses more view state,  start/end of PreInit etc. This type of information appears at the bottom of the page.

Tracing can be enable at Page level and Application Level


Page Level: You can add a Trace="true" in the page directive.
<%@ Page Language="C#"  Trace="true" %>

Application Level: The user can enable Application level tracing in the Web.config file.
By doing this the user will get trace information for all pages in your application.


<configuration>
                <system.web>
                       <trace enabled="true" />
                </system.web>
</configuration>



Happy Tracing.
