Once you purchase Telerik UI for Windows 8 HTML, you will want to remove the trial message that shows upon running your Windows Store App, which uses a
control from the suite. This help article elaborates on the steps you can follow to replace the trial version of the controls with a developer one.
How to Hide the Trial Message After Obtaining a Developer License
To hide the trial message, you must upgrade your Telerik controls to a developer version of the installation. To do so, follow the steps below:
Uninstall the trial version of the suite. To do so, go to Control Panel, locate and uninstall
Telerik UI for Windows 8 HTML QX 20XX.
Choose one of the options for installing Telerik UI for Windows 8 HTML (the non-trial version)—
manually—and perform a new installation of a licensed
version of the product.
If your choice of installation provides an SDK, you should update your project references.
Open your project and expand its References node. Remove any old references to
Telerik UI for Windows 8 HTML and add a new one to the version of the suite that you have just installed and rebuild your app.
If all has gone well, you should not see the trial message anymore.
