Dear DevExpress Support,
we are currently building a view for planning purposes based on your scheduler control. The Scheduler is grouped by resources and uses the TimelineView only.
If there are more appointments in one time cell than there is room to display, the MoreButton appears.
However, since we are not using the DayView, nothing happens after clicking the arrow.
The effect we'd like to achieve is having a collected tooltip (like the appointment flyout) to open for all hidden appointments.
We are also building this view for our web client using the DevExtreme scheduler. The DevExtreme scheduler offers the appointment collector to achieve this behaviour.
Unfortunaltely we were not yet able to find a similar function in the DXScheduler component or find any other way to customize its behaviour for our needs.
Is it possible to open some kind of popup for hidden appointments in the TimelineView?
Or is it possible to override the cell template to create this behaviour by hand?
The TimelineCellViewModel of the CellContentTemplate does not offer any information about appointments connected to the cell.
Yes, it is possible to show hidden appointments in a flyout when the More buttons is clicked. For this, subscribe to the MoreButtonClick event, obtain appointments from the corresponding interval and associated with a specific resources and then manually show the collection of appointments in a flyout.
I have prepared and attached a simple sample project demonstrating the main idea of this approach in action. Please take a moment to review it and let me know if you have additional questions.
