Hello.

When use dpn.select(dt) with dt not in visible range navigator should always switch to month which contains selected date.

Now the logic is sometimes incorrect, especially when you try to implement "prev - next" logic. It seems that you use a 90 days interval logic to switch visible range. It is not correct, it must be more complex. Just try dt.AddDays(7) and you will see that switching not always happens when you expect it to happen.

The logic should be somthing like that:

with (DPNavigator) {
var endDate = startDate.addMonths(showMonths);
if ((selectionStart.d < startDate.d && selectionEnd.d < startDate.d) || (selectionStart.d >= endDate.d && selectionEnd.d >= endDate.d)) {
moveMonth((selectionStart.d < startDate.d ? -1 : 1) * skipMonths);
}
