RadDateTimePicker for WPF

Description

How to limit selection when the DateSelectionMode property is Month.

Solution

Create a custom StyleSelector and disable the months by setting the IsEnabled property of the CalendarButtonContent. After that, set the StyleSelector to the MonthButtonStyleSelector property of the RadDateTimePicker.

[C#]

{{region kb-datetimepicker-limit-selection-in-dateselectionmode-month-0}}

public class MonthSelector : StyleSelector
{
    public override Style SelectStyle(object item, DependencyObject container)
    {
        CalendarButtonContent content = item as CalendarButtonContent;
        if (content != null)
        {
            var monthsToEnable = new List<string>() { "Mar", "Jun", "Sep", "Dec" };
            if (!monthsToEnable.Contains(content.Text))
            {
                content.IsEnabled = false;
            }
        }
        return base.SelectStyle(item, container);
    }       
}
