13 Jun 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.

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


  • 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.


Recommended place to register the license for Java platform is given below.

Import ‘syncfusion.licensing’ package and register the license key in the main method of your console application.

// Refer the licensing package
import com.syncfusion.licensing.*;

static void main() { 
// Register Syncfusion license 
SyncfusionLicenseProvider.registerLicense("YOUR LICENSE KEY"); 


License key registration is not required for Java before v19.1.
