Cycling through months Events

[Kyle]

Hi.  I need some guidance with the Scheduler. Im basically retrieving a a list of records from the DB using the EF.  I am currently binding this to the scheduler and it works like a charm. I am also populating a grid view right under my scheduler with all the appointments irrelevant of what current month the scheduler is on.

Now, i have a new requirement whereby i only show the appointments in the grid and scheduler of the selected months. So i need to filter my results (list) when the user selects the left or right arrow to cycle through the months.  I will then need to identify the start date and end date of that month and filter with a where clause on the list i have in real time. 

What event must i use to be initiated once the user selects one of this arrows which will also provide me the next/previous months and their days?

Is this possible please? I have been searching many examples, though i keep finding examples of specific people that fit to their needs. I do feel that im close but cant get around it.

I am currently binding my scheduler this way and listing everything.. So i just need to do the same thing but filtering using a where clause in the entity framework by getting the start date and end date of the month the user has selected.

private void BindScheduler()

        {

            #region Scheduler

            List<AppointmentInfo> appList = new List<AppointmentInfo>();

 

            DateTime startDate, endDate; // Coming from the db, just removed the code below in the for loop.


            string name;

             

            for (int schedCount = 0; schedCount <= _groupScheduleList.Count - 1; schedCount++)

            {

                Appointment appSched = new Appointment();

 

                appSched.ID = schedCount;

                appSched.Start = startDate;

                appSched.End = endDate;

                appSched.Subject = name;

 

                AppointmentInfo appI = new AppointmentInfo(appSched);

 

                appList.Add(appI);

            }

 

            timeSlotScheduler.DataSource = appList;

            timeSlotScheduler.DataBind();

            #endregion

        }



Update:
Im going to see if i will manage using e.Command.ToString(); I will then know if i can add months or minus.. will see if i sort out what i need this way.

Hi,

An easy and convenient way of achieving such functionality would be use the RadScheduler NavigationCommand server-side event. This event is fired when user clicks on the left or right arrow in order to navigate to previous/ next time period. 
//markup code

<telerik:RadScheduler ID="RadScheduler1" runat="server"  OnNavigationCommand="RadScheduler1_NavigationCommand">

</telerik:RadScheduler>

//code behind

protected void RadScheduler1_NavigationCommand(object sender, SchedulerNavigationCommandEventArgs e)
    {
        if (e.Command == SchedulerNavigationCommand.NavigateToNextPeriod)
        {
            //here goes the custom logic if user has clicked on next period button (right arrow)
        }
        else if (e.Command == SchedulerNavigationCommand.NavigateToPreviousPeriod)
        {
            //here goes the custom logic if user has clicked on previous period button (left arrow)
        }
    }

Thanks.. I had come up with a similar solution by converting e to string.. though this is much more straight forward.

thanks a lot :) Have implemented it.
