If you are using the controls from 2019 R1 SP1 or later, you can use the following workaround in order to make the input elements visible until we include the fix internally:
<style>
.t-ff input[type=checkbox].rfdRealInput,
.t-ff input[type=radio].rfdRealInput {
position: static;
}
</style>
Hello Guys,
For the latest version, the following script seems to fix the issue with the missing checkboxes/radiobuttons.
Please place the following script under the ScriptManager on the page, and if there are any issues remaining, share them so that we can address them.
Telerik.Web.UI.FormDecorator.ClassicDomDecorator.prototype.shouldDecorateRadioButtonsAndCheckBoxes = function () {
var browser = Telerik.Web.Browser;
return !(browser.webkit || browser.edge || browser.ff);
}
Regards,
