RadScheduler passing data to AdvancedForm

[Stuart]

I am writign a scheduler program that handles drag and drop appointment from a RadGrid. I need to pass a certain amount of data to the AdvancedInsert form via custom attributes, but I can't figure out how. I have tried using ISchedulerTimeSlot.FormContainer.Appointment.Attributes and ISchedulerTimeSlot.Appointments[0].Attributes but in both cases null is returned and crash the program. I am trying to use the AdvancedInsertTemplate inline rather than via a usercontrol and controlling the form via the FormCreated method.

My current code:

        
protected void AppointmentList_RowDrop(object sender, GridDragDropEventArgs e)
        {
            GridDataItem dataItem = e.DraggedItems[0];

            string id = (string)dataItem.GetDataKeyValue("ID");
            string customer = (string)dataItem.GetDataKeyValue("Customer");
            string title = (string)dataItem.GetDataKeyValue("Title");
            string jobtype = (string)dataItem.GetDataKeyValue("JobType");
            string targetSlotIndex = TargetSlotHiddenField.Value;

            if (targetSlotIndex != string.Empty)
            {
                HandleSchedulerDrop(id, title, customer, jobtype, targetSlotIndex);
                TargetSlotHiddenField.Value = string.Empty;
            }

            ISchedulerTimeSlot slot = AdeoJobScheduler.GetTimeSlotFromIndex(targetSlotIndex);
            AdeoJobScheduler.ShowAdvancedInsertForm(slot.Start);
// Pass extra details for JobType, Subject here

        }

        protected void AdeoJobScheduler_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
        {
            RadScheduler scheduler = (RadScheduler)sender;

            if (e.Container.Mode == SchedulerFormMode.AdvancedInsert || e.Container.Mode == SchedulerFormMode.AdvancedEdit)
            {

                RadDateTimePicker startInput = (RadDateTimePicker)e.Container.FindControl("StartInput");
                startInput.SelectedDate = AdeoJobScheduler.DisplayToUtc(e.Appointment.Start);

                RadDateTimePicker endInput = (RadDateTimePicker)e.Container.FindControl("EndInput");
                endInput.SelectedDate = AdeoJobScheduler.DisplayToUtc(e.Appointment.End);

                RadMultiSelect fitterlist = (RadMultiSelect)e.Container.FindControl("SelectFitters");

                foreach (Fitter.Result fitter in GetFitters().GetAwaiter().GetResult().results)
                {
                    MultiSelectItem newFitter = new MultiSelectItem() { Text = $"{fitter.properties.firstname} {fitter.properties.lastname}", Value = fitter.properties.id };
                    fitterlist.Items.Add(newFitter);
                }

            }
        }

 

Any help greatly appriciated.

We have already answered this question in your private support ticket so for reference I am sharing the response:

We would suggest a different approach based on the Client-side API of the controls to be used.

Please refer to our Creating Appointments with Drag-and-drop live demo, showing the integration of RadScheduler with the drag-and-drop feature of RadTreeView. The approach in the demo can be applied to the current case as RadGrid exposes similar client-side functionality as the TreeView control.

In short, you can use the Client-side OnRowDropping event of the RadGrid to gather all the needed information out of the GridItem. Then create a new appointment.

Please review the demo linked above and try reusing the approach to achieve the desired behavior.
