Licensing

Licensing Scenarios​

There are 2 possible licensing scenarios:

1. Using the default 45-day trial mode.

All features are available and can be evaluated for a 45-day period, after which an exception will be thrown. To use this mode, no license key is required.

2. Licensing the component (key starts with DGP)

Xceed DataGrid for WPF license keys permanently unlock the component's complete feature set.

How to use your License Key​

Once the references to the assemblies have been added to your project, the LicenseKey property of the Licenser class must be set in order to register your Xceed component for runtime use. If a license key is not set, the component will function in trial mode for 45-days on your development machine only.

The LicenseKey property of the Licenser class must be set with a valid license key, before any other method of your Xceed component is called. If you use an invalid license key, expired trial key, or license it in the wrong place in your code, an exception will be thrown at runtime.

It is recommended that the LicenseKey property be set in one of the following locations:

LocationDescription
Application.OnStartup methodPreferred location.
Window.Loaded or Page.Loaded eventsThe LicenseKey property can be set in this event as long as the startup page or windows is known and invariable.

Setting the LicenseKey property of the Licenser class defined in the Xceed.Wpf.DataGrid assembly will automatically license the classes in the Xceed.Wpf.Controls assembly. The following code demonstrates how to set the LicenseKey property in the Application.OnStartup method override.

protected override void OnStartup( StartupEventArgs e )
{
Xceed.Wpf.DataGrid.Licenser.LicenseKey = "place your license key here!";
base.OnStartup( e );      
}
