I have been using syncfusion essential studio 7.3.0.20. Syncfusion schedule control for windows form is seemed a very sophisticated one. It has several very sophisticated features. Among them drag and drop feature is seems to be an excellent. The syncfusion technical support responded to my queries very quickly. I really appreciate it. But I have unpleasant experiences with the syncfusion schedule control too. I have listed down those experiences below 1. Even though, I rebound the datasource to the schedule control, the schedule was not updated at runtime. According to me this is an essential feature to the schedule control. I was received a patch for this issue from the syncfusion support. After applying the patch it worked fine. 2. Dragging and dropping an item within the same cell(without taking it out from the cell) gives an exception. 3. The behavior of the Drag and drop within the schedule grid and the drag and drop from scheduled grid to the navigational calendar is different. 4. Full week view shows a different week. (The patch received from syncfusion support fixed it.) 4. Every events that I registered with the schedule control has to reregister again and again, in every action done on the user interface 5. In celldrawn event it gives the dates of the schedule grid cells in different formats and totally deviated date values from the actual value. I think it will be usefull to the syncfusion development community If you could add the following features to the schedule control, 1. Item swapping 2. If it is possible to expose a property to the user to define a number as a maximum conflict which can be shown at the same time in day view will be useful. 3. To the tooltip of the appointment an additional property can be added which is not available in the isheduleAppoinment interface 4. Starting day of work week view cannot be changed, if we can change it by changing a property, it will be useful. 5.According to my experience , as the item changing event is fired after removeItem and Additem methods, If we cancel the item changing, it needs to recall additem and remove item. If the firing order can be changed then we can do the validations first and if it passes then we can change the item. 6. In the appointment which has the false value for the allowDrag property, shouldnt be movable. In schedule grid it is movable. (then it comes back to the original position) 7).If we can access the appointments related to the cell at the celldrawn event, it’s very useful. I suppose these comments would be constructive to the next releases of Syncfusion and the benefitial to the Syncfusion development community.
