Hi,

I created a usercontrol base on a ScheduleView. My user control contain a "OnCanDrop" event and a "SetDataSource" method. When I create my UserControl, I fill the view with ReadOnly slots. The user can use the "SetDataSource" method to fill the view with "Appointments" and "SpecialSlots". Appointments is for appointments and SpecialSlots is for open slots where user can drag apointments into it of where user can create new appointments.

My objects (appointments and special slots) contain specifics members for logical purpose.

What I'm trying to do in my a drag and drop behavior, it's to raise my event with the source appointment the user is dragging and the specialslot where the user is trying to drop or drag over so the user can decide if the appointment is trying to drag can be drop or not on the specialslot I raised through my event base on a logic he decided.

If I have an appointment from 8h00 to 8h15 and I want to drag it in the special slot 8h15 to 8h30. I want to raise my event only when I'm over the special slot not after each mouse move of my appointment.

Thank's
Alain

Hello Alain,

I have already answered you almost the same question in the following forum thread:
http://www.telerik.com/forums/detexting-if-i-am-on-the-same-slot

You didn't answered anything there, did you give it a try and if so why it didn't work for you? I'm afraid this would be only solution for the desired scenario we can suggest with the current implementation of the ScheduleView.

Hope this helps.

Hi Kalin,

I'm sorry I didn't get the reply :(

I cannot use SnapAppointments in my approach because I need to let the user drag an appointment to a minute close to his current start time.

Regarding the other issue, with the destinationslots, I need to cast it in my own object to access a specific member when raizing my vent?!?

Thank's
Alain

Hi Alain,

As Yana has already explained in the other this forum thread the only solution for the DestinationSlots question would be to manually check whether the SpecialSlots collection contains a Slot that overlaps with the destination one using the IntersectsWith extension method. Check the attached sample project which demonstrates the exact approach.

Hope this will work for you.
