Xceed's .NET components can be used without a license key for a 45-day trial period. During this time, the components are fully functional. However, trial period reminder notices will be displayed for the duration of the trial or until a registered license key is set in your code.
The trial period for Xceed's components begins at the time of installation. Once the trial period has ended, a registered license key is needed to continue using them (see the How to license a component once you purchase page for details). If you attempt to use a component after the trial period without a registered license key, an exception will be thrown and you will not be able to use it.
Using Xceed's .NET components during the trial period
All you need to do is the following:
1- Install the components using the Xceed Installer application. There is no need to set a license key.
2- Try the components for up to 45 days.
3- Purchase a license to continue using them or to deploy your application.
Deploying to another machine for testing purposes
If you wish to temporarily deploy an application to another machine for testing purposes during the trial period, follow these steps:
1- Get a temporary license key from the Xceed Component Licenser application, which is normally found under the Xceed Components folder in the Start Menu.
2- Set the component's Licenser.LicenseKey property with this temporary license key. For detailed instructions, see the LicenseKey property section on the How to license the component once you purchase page.
3- Compile your application and deploy it to the test machine.
Special Considerations for Xceed DataGrid for WPF
There are 3 possible licensing scenarios:
1- Express Edition (starts with DGF)
Your Express Edition license key (starts with DGF) is automatically sent by e-mail when you register to download Xceed DataGrid for WPF. If the component is unlocked using an Express Edition license key, all features available to users of the Express Edition will be permanently unlocked. Features reserved for the Professional Edition (e.g., Fixed columns) will be disabled and throw an exception if they are used. To evaluate the features that are reserved for the Professional Edition, refer to scenario 3.
2- Professional Edition (starts with DGP)
Xceed DataGrid for WPF Professional Edition license keys (starts with DGP) permanently unlock the component's complete feature set.
3- Using the default 45-day trial mode (no license key).
Features available only in the Professional Edition (e.g., Fixed columns) can be evaluated for a 45-day period after which an exception will be thrown. To use this mode, no license key is required.
For the ActiveX products, regardless of if you are using a trial or registered version of Xceed components, the License method must be called before any other of the components methods or properties.
