Are you are a licensed developer but you still sometimes get the trial message when you run a page with Telerik UI for ASP.NET AJAX (a.k.a. RadControls for ASP.NET AJAX) in the browser?
Thank you for using the Trial Version of Telerik® UI for ASP.NET Ajax to build more powerful applications faster. Purchase the Commercial Version now to get access to all product updates and the Telerik expert support.
The error text for the older version is a bit different:
Telerik.Web.UI 201X.X.XXX.XX trial version. Copyright Telerik © 2002-201X. To remove this message, please purchase a developer version.
This error means that you are still using the trial version of Telerik.Web.UI.dll! There is a couple of different ways to check whether the Telerik.Web.UI.dll assembly is a trial or a purchased one:
If you download your files from your Telerik.com account, make sure that they are DEV (the purchased) builds, to ensure that you not see a trial message, e.g.
If you have installed a trial build (Telerik_Web_UI_for_ASP.NET_AJAX_XXXX_X_XXX_Dev.msi), it is recommended to uninstall it completely, download the Dev executable from your account and install it. More information on the subject is available in the following help article: Upgrading a Trial to a Developer License or to a Newer Version.
