In the following sample, all the weekends (Saturday and Sunday) of a month are disabled, and these dates are restricted to set or select in the DatePicker.
Disabled Dates sample demonstrates how to disable specific dates in the DatePicker by using the renderDayCell event. This event gets triggered on each day cell element creation, that allows you to customize or disable specific
dates in the DatePicker. Here, the weekend dates are disabled by using renderDayCell.
More information on the disabled dates can be found in the documentation section.
