How to get selected time period

[Marcus]

Hi,

I have a RadScheduler that I've set up to drag and drop different tasks from a list box. Currently the task only fills one time slot (which is set at half-hour intervals) however I would like the user to be able to select a time period and drag the task to the selected area and have the "appointment" fill the entire selected area. 

I am having trouble retrieving the selected time period from the WinForms scheduler, is there a way to get the selected TimeSlot?

Thanks is advance,

Marcus

Hello Marcus,

Thank you for contacting us. I have prepared a simple solution how to get the selection start and selection end dates.

1. Get the dayview element instance from RadScheduler.

  SchedulerDayViewElement dayview = (this.radSchedulerDemo.SchedulerElement.ViewElement as SchedulerDayViewElement);
2. Get the selection MinDate and selection MaxDate. I'm doing this by iterating over the cells collection. Then check whether a cell is selected and initialize the minDate and maxDate fields:

            DateTime minDate = DateTime.MaxValue;
            DateTime maxDate = DateTime.MinValue;

            foreach (RadElement element in dayview.DataAreaElement.Table.Children)
            {
                SchedulerCellElement cell = element as SchedulerCellElement;
                if (cell != null && cell.Selected)
                {
                    if (minDate >= cell.Date)
                    {
                        minDate = cell.Date;
                    }

                    if (maxDate <= cell.Date)
                    {
                        maxDate = cell.Date;
                    }
                }
            }

            TimeSpan selectionDuration = maxDate - minDate;

I hope this helps. Do not hesitate to write me back if you have further questions.

Thanks! That almost got it, I just had to add time to the end of the max date (thirty minutes in my case) to find the time period from the beginning of the first cell to the end of the last cell.

Thanks for the help.

Hi 
How would this be applied in VB.Net as the line 

dayview = TryCast(Me.radSchedulerDemo.SchedulerElement.ViewElement, SchedulerDayViewElement)

does not return anything for a selection event

[Ivan Todorov]

Hi Denis,

This is the correct way to get the SchedulerDayViewElement, however you can get it only if RadScheduler is currently under DayView. Otherwise the ViewElement will be of different type and the TryCast will return Nothing.

If your goal is to get the selected dates, then you can use the following method to achieve this without having to cast any elements:

Dim dates As DateTime() = SchedulerUIHelper.GetSelectedDates(Me.RadScheduler1)
Array.Sort(dates)
Dim interval As New DateTimeInterval(dates(0), dates(dates.Length - 1))

If your requirement is different, then please share more details on it and I will assist you in achieving it.

Should you have any other questions, feel free to ask.

How do I do this in VB.net. It loops through the 72 cells but everyone seems is selected = false.

[Ivan Todorov]

Hello Gerhard,

The approach should be the same in C# and VB. However, you can try using one of the following methods of the SchedulerUIHelper class:

SchedulerUIHelper.GetCells(Me.RadScheduler1)
SchedulerUIHelper.GetSelectedCells(Me.RadScheduler1)
SchedulerUIHelper.GetSelectedDates(Me.RadScheduler1)

If you have any additional questions, please let me know.

Hello Telerik team,

 I have a Radscheduler and an individual button, in a web form in my aspx page(c# and Asp.net).

when in week view of the scheduler, it displays the first week (i.e)  jan 3 2016 sunday to jan 9 2016 saturday,

i want to view the next week on button click (i.e)  jan 10 2016 sunday to jan 16 2016 saturday,

telerik has dayview, weekview, monthview, agendaview and timelineview but not nextweekview..

Googling does not help me in this case.

 

Thanks in advance..

Hope you people reply a bit faster.
