In Asp.Net Web Forms has a configuration files,which is know as Web.config,which is used to provide settings for each Web Forms page in the same directory and its subdirectory.
To set the web forms globalization setting we use <globalization /> element tag in we.config file.
<configuration>
<system.web>
<!--we use this section for setting globalization setting-->
<globalization fileEncoding="utf-8"
requestEncoding="utf-8"
responseEncoding="utf-8"
culture="en-US"
uiCulture="de-DE"
/>
</system.web>
</configuration>
we can also specified all attributes of globalization in the @page directive only fileEncoding attribute need to set in web.config.if fileEncoding is set at the @page directive it will show exception.
