The read-only property available on most kendo input fields isn't obvious enough for the end user that a field is disabled. It is a source of confusion as it makes the form look broken rather than read-only. Adding k-state-disabled is important from a form readability perspective, thus it would be very helpful if that class was made available on dropdown lists and masked textboxes so they match the textboxes on forms without having to selectively apply additonal CSS.

Instead of only supporting single character masks, I suggest support be added for group masks.

Example:

$("#time").kendoMaskedTextBox({
     mask: "HH:MM TT",
     rules: {
               "HH" : /^(([0]?[1-9])|([1][0-2]))/,
               "MM": /(([0-5][0-9])|([1-9]))/,
               "TT": /[AaPp][Mm]$/
     }
});

or

$("#time").kendoMaskedTextBox({
     mask: "t",
     rules: {
               "t" : /^(([0]?[1-9])|([1][0-2])):(([0-5][0-9])|([1-9])) [AaPp][Mm]$/
     }
});

Method to modify mask in MaskedTextbox

Date/DateTime/Time pickers need to have a mask automaticly for the date format entered currently users need to type the "/" instead of a mask "__/__/____"  like in telerik ajax. 
I know there is this link 

http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/datepicker/how-to/masked-date-picker-grid

With a solution but this is a workaround and not a built in solution supported by telerik.
