In order to prevent the items from spanning entire cells, set the ShowPadding property in the TimetableSettings to Disabled.

Additionally, if you want to prevent the items from snapping to cell borders during interactive modification, set EnableSnapping to Enabled and specify a desired interval through the SnapInterval property (for example, 1 minute).

There is no automatic way to achieve this. However, with proper event handling, you can attain similar effect. You will have to handle the ItemModifying event, perform the necessary calculations to see whether the modified item is close enough to another item and adjust the values of the NewStartTime and NewEndTime properties in the accompanying EventArgs object accordingly.

In order to render a snap line, you have to use custom drawing. To do this, set the appropriate value to the Calendar.CustomDraw property (TimetableCell for example) and handle the Draw event.
