  Hello, I am looking for some advice on how I can allow a user to click an item in a standard list box, drag it onto a particular date in a C1Calendar control and have it create a schedule for that item on that date. The items in the list box have ID values and the schedule item created will need to include that ID value.

  An example of what I am doing, ListBox1 has a list of Names. If A user drags John Doe (ID of 12) onto January 27th, I want to create an appointment on January 12 for UserID 12.

  Thanks,

  Mike

  One quick related question…when a user drags and appointment from one day to the other, how do I update the underlying data set with the new date? Thanks,

  Mike

  Hi Mike,

  When you drag drop an appointment, the AppointmentChanged event will fire. Inside this event handler you can save the update. In the following code, we are updating the database value through an OleDbDataAdapter.```
  
  private void C1Schedule1_AppointmentChanged(object sender, AppointmentEventArgs e)
  
  {
  
  this.appointmentsTableAdapter1.Update(c1NWindDataSet1.Appointments);
  
  c1Schedule1.Refresh();
  
  }

  Thanks,
  Ruchir
