Currently RadCheckBox follows the guidelines of the operating system, meaning that on iOS it is visualized as circle and on Android and Windows - as square.

Hi Team,

With CheckBoxes and RadioButtons, there is a concept of Button GroupName... where if belonging to a group, a selection is mutually exclusive to that group.

Here is the official docs from Microsoft for the same feature in WPF => https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.radiobutton.groupname?view=windowsdesktop-7.0 

Thank you,

Glenn
