Register Syncfusion License key in ASP.NET application

14 Jul 20221 minute to read

The generated license key is just a string that needs to be registered before any Syncfusion control is initiated. The following code is used to register the license.

C#

Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY");

NOTE

• Place the license key between double quotes. Also, ensure that Syncfusion.Licensing.dll is referenced in your project where the license key is being registered.
• Syncfusion license validation is done offline during application execution and does not require internet access. Apps registered with a Syncfusion license key can be deployed on any system that does not have an internet connection.

ASP.NET Web Forms

You can register the license key in Application_Start method of Global.asax.cs/Global.asax

C#

void Application_Start(object sender, EventArgs e)
{
	//Register Syncfusion license
	Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY");
	
	// Code that runs on application startup
	RouteConfig.RegisterRoutes(RouteTable.Routes);
	BundleConfig.RegisterBundles(BundleTable.Bundles);
}

VB.NET

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
	'Code that runs on application startup
	AuthConfig.RegisterOpenAuth()
	RouteConfig.RegisterRoutes(RouteTable.Routes)
	System.Web.Http.GlobalConfiguration.Configuration.Routes.MapHttpRoute(name:="DefaultApi", routeTemplate:="api/{controller}/{action}/{id}", defaults:=New With {.id = System.Web.Http.RouteParameter.[Optional]
	   })
	'Syncfusion Licensing Register
	Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY")
End Sub
