Hello,

Just to be clear on the commercial license agreement, I'm prohibited from changing any part of the source code? Even for internal use where it would not be distributed, it does still violate the agreement? So for example, if I don't like the pager on the Kendo Grid and I want to have a First and Last buttons, my only real option to be in agreement with the license is to contact Telerik, and ask them to support a feature (if they even accept it), and wait for the release?

Hello Matthew,

Under a commercial license, you can modify the source code and use it minified, internally in your Integrated Product (as defined in the license agreement). You cannot repackage, distribute or sell the modified version of Kendo UI. Also, please note that our support packages do not cover the modified versions, and that your upgrade path will be much harder -- so submitting feature requests may save you some headaches, even if you decide to implement them faster than us. 


Kind regards,

Hello Alex,

According to section #1 (Licensed Use of the Software), "Except as expressly granted in this Agreement, You are not licensed to use, copy, modify, or distribute copies of all or any portion of the Software."

The section 1.2.1 (Developer License Grant) says "If You purchase a Developer License, Your Licensed Developers may use the Software in source and minified form in the development of Your Integrated Products."

However, from my understanding, there's nothing in the section 1.2.1 (or any other section) that would grant us the right to modify the source code.

Can you point out which statement of the licence agrement is grating us the right to modify the source code?

Best regards,

Simon

Hi Simon,

Thank you for contacting us!

You can find a similar statement under the license agreement of Kendo UI Complete which includes Kendo UI Web as well: (http://www.kendoui.com/get-kendo-ui/purchase/license-agreement/kendo-ui-complete-commercial.aspx)

1.2.5.4  Pursuant to Section 1.2.5.1, You are not permitted under this Agreement to modify the source code for the Software. However, if You disregard this prohibition and develop any troubleshooting-related modifications of the Software independently, or if You contact Telerik for assistance with the Software and modify the source code for the Software jointly with Telerik, such modifications and all rights associated therewith will be the exclusive property of Telerik, and You agree to and hereby do assign all right, title and interest in and to such modifications to Telerik.

In other words as Alex mentioned in his previous email you can modify the source code and use it minified, internally in your Integrated Product but you cannot repackage, distribute or sell the modified version of Kendo UI. Please also note that support from Telerik will not be provided for any products that you have modified yourself. 

I hope this helps. 

Please let me know in case you have any further queries.
 
All the best,
Mili

If you use the gnu licensed version you can mod and redistrubute to hearts content, but in doing so you forfeit a lot of customer service that comes with the other licensing options, and lose options relating non-open development.  Just a thought if redistribution of modded source code is important.
