Set default error page Asp.net
In this article i am going to share that how to set the default error page for your website . Every web application should have a custom error page. It provides a more professional-looking alternative to the Runtime Error .
Change the following line of code in your Web.Config file.
<configuration>
<system.web>
<customErrors mode="Off" defaultRedirect="Error.aspx" />
</system.web>
</configuration>
The <customErrors> section in Web.config has two attributes defaultRedirect and mode.
defaultRedirect :- It indicate the url of the error page.
mode :-it accepts three values On,Off,RemoteOnly.
Replace Error.aspx with the name of your Error page name.
