Currently, the new feature .ComponentType('modern') does NOT respect the .Interval(n) setting for the control.
Demo of ComponentType setting on DateTimePicker control
According to the API Reference the Interval setting, Interval
"Specifies the interval, between values in the popup list, in minutes."
The ComponentType('classic') does respect the Interval setting. Thus, the ComponentType feature should be updated to respect the Interval setting when the "modern" ComponentType is selected. The time interval under modern is always 1 minute (see screenshot).
@(Html.Kendo().DateTimePicker() .Name("SessionEndDateTime") .Interval(15) .ComponentType("modern") .Events(e => { e.Change("onSessionEndChange"); }) .HtmlAttributes(new { style = "width: 100%", title = "Session End Date/Time", @class = "form-control" }) .DateInput() )
Modern should respect the Interval setting for the control.
