How to create Custom Application Settings in the web.config

In the web.config file add a key-value pair as follows:

<configuration>
<appSettings>
	<add key='PageSize' value='10'>
	</add>
</appSettings>
</configuration>

Then you can access the settings as follows in code:

VB.NET

Response.Write (ConfigurationSettings.AppSettings('PageSize'))

C#

Response.Write (ConfigurationSettings.AppSettings['PageSize'] );
