Here’s another update of DateTimeControls. I’ve added a new property “Value”. You may wonder why I did this, as there’s already the “CurrentDate” property. Well, “CurrentDate” is of type “Date”. This causes problems with data-binding if the table contains NULL values. Those NULL values should be handled as “no selection made”, i. e. the “DateSelected” property should be set to “False” on such a NULL value. However, you would need to bind 2 properties for 1 column. I doubt this is possible.
I could have changed the type of “CurrentDate” to “Variant” and change its implementation so that setting this property to a NULL value is handled as if “DateSelected” was being set to “False”. But this would have broken binary compatibility. Therefore I introduced a new property that combines “CurrentDate” and “DateSelected”.
I’ve finished two new controls: A date-time picker and a calendar. If you’re tired of the no-themes-support of the corresponding controls from Microsoft, you should give the new controls a try. Of course they also support Unicode, drag’n'drop and so on.
The controls are my hobby and I’ve not much spare time, so don’t expect too many releases in 2009. But I’ll release a highly updated ExplorerListView control soon. The next new controls (among ShellBrowser) will be ComboBox, DriveComboBox, ImageComboBox and ListBox.
Oh, by the way, DateTimeControls officially supports Windows 7 Beta 1.
