Scroll Schedule when dragging appointment

Hi,

In week view, is it possible to auto scroll the schedule when dragging the appointment to the right or left edges of the current view, thus allowing appointments to be dragged into another week?

Does anyone have any working sample code?

Thanks

Split day into multiple slots in grouped-by-resources timeline view radscheduler?

I have a grouped by resources scheduler in timeline view with the timescale set to days and I'd like to set the so called "slot-duration" to half-day for the day cell, which can already be done in the aspnet ajax version I link below. Is there a way to achieve this functionality in c# winforms?

Basically I'd like to divide the day slots into two parts to track absences, which can have a half day and full day duration.

RadScheduler - Adding events programmatically.

I am using the radScheduler for the first time. I am trying to bind some data to it (or even add events programmatically) that we are receiving from an RRS feed. Is there a simple way to do this. The Help files are more about binging a table/dataset to it. Note, this control is used as a READ only view of events for my customers.

TIA for the help

[Solved] Custom AppointmentElement diplay problem

Hello,

I have implemented a custom AppointmentElement and I habe a small display problem with it.

Here is a screenshot:

When the area of the appointment gets to small, the arrow on the right is no longer drawn, but i want the element to always draw it and cut the text first.

Here is my implementation:

internal class CustomAppointmentElement : AppointmentElement
{
    private AppointmentsViewModel _appointmentsViewModel;

[Solved] Limiting ResourcesPerView for grouped TimelineView

Hello,

I am using RadScheduler with a grouped TimelineView. The number of resources can be selected with a TrackBar, but if the selected value is to high, the view looks squezed and I got overlappings in my customized resource header elements. So my Idea is a minimum ResourceHeaderHeigth. I want to achieve this by calculating the maximum suitable ResourcesPerView value when the Trackbar is changed or the Form / Scheduler is resized. E.g. if my Scheduler has 250 px size, max 5 resources should be visible and if the size is resized to 200 px, only 4 should be shown, so that every resource has at least 50px height.

But to achieve this I need to get the size of the area, where the resources are paintet or SchedulerSize minus Header and Footer.

        private void tbVisibleResourceCount_ValueChanged(object sender, EventArgs e)
        {
            if (DesignMode)
                return;

            try
            {
                int val = (int) tbVisibleResourceCount.Value;

                if (val <= 0)
                {
                    tbVisibleResourceCount.Value = 1;
                }
                else
                {
                    var newValue = Math.Min(val, AppointmentsVm?.AktiveRessourcen?.Count ?? 0 /*rsTermine.Resources.Count*/);

                    /* todo
                    switch (rsTermine.SchedulerElement.ViewElement)
                    {
                        case SchedulerTimelineViewElement timelineElement:                           
                            break;
                    
                        case SchedulerDayViewElement dayViewElement:
                            break;

                        case SchedulerMonthViewElement monthViewElement:
                            break;

                        case TimelineGroupingByResourcesElement timelineGrouped:
                            IList<SchedulerTimelineViewElement> childTimelineElements = timelineGrouped.GetChildViewElements();
                            break;

                        case SchedulerDayViewGroupedByResourceElement dayViewGrouped:
                            break;

                        case SchedulerMonthViewGroupedByResourceElement monthViewGrouped:
                            break; 
                    }*/

                    rsTermine.ActiveView.ResourcesPerView = newValue;
                }

                SetAppointmentsMargin();
                _adjustBackgroundsTimer?.Reset();
            }
            catch (Exception ex)
            {
                LogHelper.HandleError<CalendarView>(this, $"Fehler in {nameof(tbVisibleResourceCount_ValueChanged)}", ex);
            }
        }

Hope you can help me with this problem.
