I provide a schedule data source which have many appointment (>200 Appointment). of one day)

<telerik:RadScheduler ID="RadScheduler1" runat="server"
            DataKeyField="AppointmentID" DataStartField="Dappt_time" DataEndField="Darrival_tim DataSubjectField="Dpatient_first_name" DayStartTime="06:00:00" DayEndTime="21:00:00">            
</telerik:RadScheduler>

My data source is a data table. (All appointments
DataTable dt = dv.ToTable();

Schedule1.DataSource = dt;
Schedule1.DataBind();   

Result, Schedule show many very tiny appointment that can't view detail appointment information.
I don't find a property to set the width of appointment item.
