I made a comment in DevComponents Feature Requests forum 8 days ago and in today's release they have added support for TextBoxX pressing Ctrl+A keyboard shortcut will select all the text to DotNetBar Suite for Windows Forms as well as a lot of other things. Thanks for a great and quick service.
Here is the Date/Time Picker where the week numbers also can be seen. If DateTimePicker that comes with Visual Studio is not enough this one might fill your needs.
If you’re a developer take a look at their nice and useful components. Several of the components like the Ribbon are used in the new JTB FlexReport client that is in beta 2 now and in a short while in beta 3. Did I mention that DevComponents support is excellent too?
