EnsureVisible in TimeTable view

I'm evaluating Planner.NET, and so far I'm excited about the possibilities. In particular, the ability to extend the control with custom editors and inherited Item types is going to be useful for us.

One thing I can't figure out: EnsureVisible sometimes does nothing at all. Example:

calendar1.Date=DateTime.Today;
calendar1.EnsureVisible(DateTime.Now);

In this case, the calendar doesn't scroll at all. However, if I drag the mouse to make a selection, click an appointment, etc., suddenly EnsureVisible works fine.

Is this a known bug, or something I'm doing wrong?
Thanks.

This actually happens when you are in a groupped view (i.e. Calendar.GroupType is set to one of the group constants). When the view is groupped you have to also specify the resource whose date you want visible to avoid ambiguity. To specify a resource, use the EnsureVisible overloaded method that accepts a resource as a second parameter. Similar to the following:

Code
Select All
calendar.EnsureVisible(date, someResource);


EnsureVisible(DateTime) works correctly when something is selected because it invokes EnsureVisible(DateTime, Resource) with a reference to the resource whose cells / items are selected.

That fixed it.

Even now that I know that, the documentation isn't clear to me. I would have expected the calendar to scroll to the specified time in the currently displayed resource. Even showing a randomly chosen resource would be better than doing nothing.

If you plan on keeping that behavior, I'd suggest you revise the documentation on EnsureVisible.

Thanks!

The behavior of EnsureVisible(DateTime) has been fixed. It should now scroll to the specified date of the first available resource when nothing is selected. This change will be available in the next official release.
