~/Telerik's WPF RadScheduleView - Double-click to create an appointment gotcha

29 April 2014

I’m using Telerik’s RadScheduleView in a WPF project. Double-clicking the grid to create an appointment suddenly stopped working.

Turns out I had changed my custom appointment subclass’s default constructor from public to protected. The schedule view needs a public default constructor or it will just silently not create new appointments:

public class MyCustomAppointment
{
    // this is required to double-click to create
    public MyCustomAppointment()
    {
        // ...
    }

    // non-default constructor can still be called in code
    public MyCustomAppointment(...)
    {
        // ...
    }
}
