RadControls are written in C# language,  however all controls come with examples in VB.NET as well. You can use RadControls in any project written in any language, supported by the .NET framework. For more information, review System Requirements.

The source code is available free of charge (under your Client.net account -> My Licenses -> My Purchases section, expanding the Downloads tab) when you purchase Single developer + subscription license. If, for any reason, you do not get the Source code within 24 hours of purchase, please write to sales@telerik.com and we will send you the source directly to your mailbox.

No, we do not offer boxed versions of our controls nor do we offer RadControls on a CD.

Below are outlined the most possible causes for the installer to fail:

1. Incomplete download. 
2. The installer package requires .NET framework versions 2.x or 3.x to be installed. If you do not have the .NET framework, the installer will show an error message saying so.
3. The installer package requires Internet Information Services (IIS) to be installed. If you do not have the .NET framework, the installer will show an error message saying so.

If the above suggestions do not work, please, log in your Client.net account and download the ZIP package of the control(s). You can find instructions on how to how to install the ZIP package in the following KB article.

You can find instructions on how to how to install the ZIP package in the following KB article: Installing Telerik's controls from the provided ZIP files. (ID# 158)

You can find instructions on how to how to update your control in the following KB article: Updating Telerik's controls to another version or license (ID# 503)

We offer fully functional trials which work without license keys and can be conveniently deployed on any development, test or production machine. The only difference between the trial and the developer build is that with the evaluation copy you will get a trial message on top of the control once in a while. Upon replacing the trial dll with the developer dll the trial message will disappear.

---

To download a trial, please log into your Client.NET account, go to My licenses -> My Free Trials and chose the respective product (usually RadControls suite).

If you get a trial license message (copyright message) then you are still using the trial version or your project was not updated properly. To update your application to use the Developer version, follow the instructions in this online Knowledge Base article: Updating Telerik's controls to another version or license (ID# 503)

Please, contact the Telerik support team and tell us which control(s) are you interested in. We will gladly send you the control by mail.

This happens when the controls have been purchased by your purchasing department or under a different account. There are two ways to proceed:

1. Contact our support officers through the online ticketing system and explain the problem in detail
   or 
2. Ask the purchaser to add your email to the developer’s list of the people who will be using the control. This way you will have access to the purchased controls and to the Telerik support services. Here are the steps:
1. Ask the purchaser to log in his/her Client.net account.
2. Once there, go to the My Licenses --> My Purchases and locate the respective control (usually RadControls). Click on it to locate the available options.
3. Open the Developer tab. 
4. Add the email and names of the developer in the text fields (i.e. your credentials)
5. Repeat the procedure for all needed controls and developers. 
6. Log in your Client.net account – you will be able to see the purchased licenses in the My Purchases page.

New major versions of the controls are automatically assigned to the developer. If you experience problems contact us through the online ticketing system and tell us which control(s) you are interested in. If you are already a licensed developer for the older version, we will fix the problem for you.
