RadDateRangePicker does not display buttons and not pop

[Gil]

Hello,

RadDateRangePicker is not working for me. The buttons do not display and of course no pop calendar as well. 

Other pickers work fine. Any idea what I am missing here

Thanks

Hi Gil,

The RadDateRangePicker supports only Lightweight rendering. As you may know, the Classic rendering is discontinued as of 2015 and is no longer supported.

To take advantage of the RadDateRangePicker control set its RenderMode property to Llightweight. It is also recommended to have all Telerik control on the page with the same render mode. Otherwise, you may experience appearance issues and side effects.

If the problem still persists after switching to lightweight rendering, make sure that the version of the Telerik.Web.UI.dll assembly is at least 2021.3.914 or later, and there are no JavaScript errors on the page.

Best Regards,
Rumen

Hi Rumen,

Thank you for your information.  I did not know ( or did not read well ) about the Classic rendering that was discontinued, so thank you for that.

Adding LightWeight rendering Mode solves the problem (  see attached photo ).  I follow your recommendation to have all Telerik Controls with the same render mode and if I avoid doing so many other controls experience some issues, as you said.

Yours

Gil

I am glad that the problem is resolved! 

Just to share it here: The information about the deprecation of the Classic render mode is available in the Render Modes article: https://docs.telerik.com/devtools/aspnet-ajax/styling/controlling-visual-appearance/render-modes, e.g.

The Classic Render Mode is in maintenance mode since Q3 2015 and only critical bug fixes are provided for it. All the new functionality, controls and features are developed for the modern Lightweight and Mobile Render Modes.
