[Solved] Issue in classic mode of Telerik v.2017.1.228.45

[Gregory]

You may see it on the official  : http://demos.telerik.com/aspnet-ajax/button/examples/rendermode/defaultcs.aspx?skin=Black

Checkboxes and Radio are not properly visualized in the Classic Rendering mode.

The issue is reproduced with any browser.

Fixed it by changing RadButton to RadCheckBox and RadRadioList  components.

Hello Gregory,

This is a known regression introduced in R1 2017 SP1. You can track its status and find the workaround you have already discovered in this page: https://feedback.telerik.com/Project/108/Feedback/Details/213217-radbutton-as-checkbox-checked-backgrounds-are-misplaced-in-classic-rendermode.

I suggest you consider rolling back to R3 2016 SP2 release, because R1 2017 releases have a few other issues (you can find them here) and R3 2016 SP2 is the most stable one at this point, until these are fixed in R1 2017 SP2 and R2 2017.
