Hi Phil,
Thanks for contacting Syncfusion Support.
In DatePicker picker component, only a single month will be displayed in the popup and a single date value will be selected. So, NavigateTo method will be beneficial with DatePicker component to navigate to a required date. Whereas in DateRangePicker component, two calendars (left and right calendars) will be displayed with consecutive months and a date range (start date and end dates) will be selected. So, NavigateTo method will not be required with DateRangePicker component as this may lead to unwanted confusions between two calendars in the popup. However, if you could share the use case for this requirement from your end, so that we can check the possibilities to achieve your requirement at our end.
Regards,
