How to Set up a website building page when working on live

Hi Danish Habib,

If you want to set web.config file Apps seating value use following code

 <appSettings>
    <add key="AppKey" value="AppValue"/>
  appSettings>

 Then in page load or button click write following code

            //Helps to open the Root level web.config file.
            Configuration webConfigApp =                                                                      WebConfigurationManager.OpenWebConfiguration("~");

            //Modifying the AppKey from AppValue to AppValue1
            webConfigApp.AppSettings.Settings["AppKey"].Value = "AppValue1";

            //Save the Modified settings of AppSettings.
            webConfigApp.Save();
