Implement a Gantt view in Scheduler

We choose another approach for this and we implemented a whole new RadGanttView control instead. Of course it can be paired up with RadScheduler. Here is the product page: http://www.telerik.com/products/winforms/ganttview-beta.aspx

Printing support

Add the possibility to have multiple time intervals for a working range and to have separate working ranges for different resources.

Add the possibility to specify given date as a holiday.

Currently, it is not possible to set for example 9:30 as a start scale for the ruler in DayView and WeekView.

Add the possibility either for the end user or the developer to modify the width or height (whichever is relevant) of the resource areas in different views.

Add vertical scroll bar to the month cell

The users will be doing a lot of drag/drop and there could be 10-15 appointments per day, so being able to see everything go makes the most sense. The row height should increace when containing more appointments and reduces its height if there are no appointments for that specific day.

IMPROVE. RadScheduler - add event that notifies when an appointment is added by the user. The event args should provide information whether the event is added via the edit appointment dialog or via the inline functionality

Please refer to the attached sample project. When you start the application the form's text indicates how many times the AppointmentFormatting event is fired for only 30 appointments - more than 400 times. The more appointments you have , the more times the vent is initially fired,e.g. if you have 50 appointmens it is fired If you switch between the different views you will see how the counter increases its value.

Currently, only one resource can be printed on a single page. It should be possible to print the appointments for more than one resource on a single page, just like RadScheduler allows you to set the number of resources per view.

Please refer to the attached screenshots. A sample project is attached.

There is a known issue in the .NET Framework considering the "fa-IR" culture. Please refer to the following MSDN resource for a solution which is included in the sample project: https://code.msdn.microsoft.com/Fixing-Persian-Locale-for-6e66e044#content

Workaround:

 private void radScheduler1_CellFormatting(object sender, SchedulerCellEventArgs e)
        {
            MonthCellElement monthCellElement = e.CellElement as MonthCellElement;
            if (monthCellElement != null)
            {
                monthCellElement.Header.Text = monthCellElement.Date.ToString("dd", this.radScheduler1.Culture);
            }
        }

1. Add RadSchedulerNavigator and a RadScheduler. Change the view type to Week View.
2. Associate the RadSchedulerNavigator to RadScheduler. Change the PC's time zone to (UTC-03:00) Brasilia Time zone
3. Change the PC's date to 21 Oct 2016 and run the application.
4. When you change the time zone in RadSchedulerNavigator to (UTC-03:00) Brasilia Time zone, you will notice that the ruler starts from 23.

Workaround: 

public Form1()
{
    InitializeComponent();

    radSchedulerNavigator1.AssociatedScheduler = radScheduler1;

    this.radScheduler1.ActiveViewChanged += radScheduler1_ActiveViewChanged;
    this.radScheduler1.CellElementMouseDown += radScheduler1_CellElementMouseDown; 
    this.radScheduler1.AppointmentEditDialogShowing += radScheduler1_AppointmentEditDialogShowing;
    radScheduler1.ActiveViewType = Telerik.WinControls.UI.SchedulerViewType.Week; 
}

DateTime? date = null;

private void radScheduler1_CellElementMouseDown(object sender, MouseEventArgs e)
{
    SchedulerCellElement cell = this.radScheduler1.ElementTree.GetElementAtPoint(e.Location) as SchedulerCellElement;
    if (cell != null)
    {
        date = cell.Date;
    }
}

CustomEditAppointmentDialog dialog = null;

private void radScheduler1_AppointmentEditDialogShowing(object sender, AppointmentEditDialogShowingEventArgs e)
{
    if (dialog == null)
    {
        dialog = new CustomEditAppointmentDialog();
    }
    e.AppointmentEditDialog = dialog;
    if (date != null && !e.Appointment.Start.Equals(date))
    {
        e.Appointment.Start = (DateTime)date;
    }
    date = null;
}

private void radScheduler1_ActiveViewChanged(object sender, Telerik.WinControls.UI.SchedulerViewChangedEventArgs e)
{
    SchedulerDayView dayView = e.NewView as SchedulerDayView;
    SchedulerWeekView weekView = e.NewView as SchedulerWeekView;
    if (dayView != null || weekView != null)
    {
        RulerPrimitive ruler = (this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewElement).DataAreaElement.Ruler;
        ruler.GetType().GetField("defaultOffset", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(ruler, 0.0f);
    }
}

public class CustomEditAppointmentDialog : EditAppointmentDialog
{
    protected override void LoadSettingsFromEvent(IEvent sourceEvent)
    {
        base.LoadSettingsFromEvent(sourceEvent);
        this.dateStart.Value = sourceEvent.Start;
        this.timeStart.Value  = sourceEvent.Start;
    }
}

Please use the Demo application >> Scheduler example and follow the steps in the attached gif file.

Expected result: the deleted appointment should disappear from the grid after closing the edit dialog.

Actual result: the deleted appointment is still visible in the agenda grid after closing the edit dialog.

Note: pressing the Delete key when an appointment is selected in agenda view doesn't perform any delete operation. In the rest of the scheduler view, the selected appointment is deleted.

Workaround: after an appointment is deleted, refresh the agenda grid by changing the view:

    Private Sub RadScheduler1_AppointmentDeleted(sender As Object, e As SchedulerAppointmentEventArgs)
        Me.RadScheduler1.ActiveViewType = SchedulerViewType.Day
        Me.RadScheduler1.ActiveViewType = SchedulerViewType.Agenda
    End Sub

this.radScheduler1.Appointments.EndUpdate();

Does not refresh the Scheduler view element.

Currently RadScheduler can only group the appointments first by resource and then by date. It should be possible to group the appointments in day view and in week view first by date and then by resource.

Implement search function in RadSchedulerNavigator.

The appointments area of RadScheduler in DayView or WeekView should be automatically scrolled when resizing appointments.
