Updating appointments with TableAdapters

[FB]

Hello,

I have a form that uses databinding using Dataset/TableAdapter for the Appointments. I have one table - Appointments. If I were to use a button to update the dataset to persist the data, will I still need to hit the "Ok" button before I hit the Update button? I am using the Timeline view and it displays the appointments from table correctly. However, after dragging to new start and end date, I have to select "All day event" then hit Ok and then the update button before my changes are saved.

What am I doing wrong?



Thanks.

Hello FB,

Thank you for your question.

There is a known issue in RadScheduler with updating the data source when changing appointments' start date via drag and drop. By hitting the 'All Day Event' you force an update of the data item and that is why this saves your changes. We will try to address this issue in the upcoming Q2 release. For the time being, I can only suggest you to change appointments' start date through the appointment edit dialog.

I hope this helps.

Best wishes,

Thanks Ivan,

Can I not, somehow, make use of the move, resize events if they exist? Check if the start/end dates have changed and save to database?


Thanks

Hi Fb,

I have made some further investigations on this case and I have managed to think of a workaround. It handles the Appointments.CollectionChanged event and updates the appointments manually. The following code snippet demonstrates this:

AddHandler Me.RadScheduler1.Appointments.CollectionChanged, AddressOf Appointments_CollectionChanged


Private Sub Appointments_CollectionChanged(sender As Object, e As Telerik.WinControls.Data.NotifyCollectionChangedEventArgs)
    If e.Action.Equals(Telerik.WinControls.Data.NotifyCollectionChangedAction.Batch) Then
        For i As Integer = 0 To Me.radScheduler1.Appointments.Count - 1
            Dim app As IEvent = Me.radScheduler1.Appointments(i)
            Me.radScheduler1.DataSource.GetEventProvider().Update(app, "Start")
            Me.radScheduler1.DataSource.GetEventProvider().Update(app, "End")
            Me.radScheduler1.DataSource.GetEventProvider().Update(app, "Duration")
        Next
    End If
End Sub

The issue will most probably be addressed in the upcoming Q2 release. For the time being, I hope this will help you.

If you have any further questions, feel free to ask.

Hi Ivan,

Thanks for your prompt reply. Yes it does! As a matter of fact I made use of the AppointmentMouseUp event. Wrote a function that makes call to the database. This way the appointments are saved everytime they are dragged or moved.

Regards and looking forward to Q2 release.
