Controls « 2,000 Things You Should Know About WPF. When using a DatePicker control, you can either use the dropdown calendar to select a date or you can manually enter a date in the text area.
When the DatePicker converts the string that you enter into a date, it uses the DateTime.Parse method, which in turn uses the valid date/time formats for your current culture to convert from a string to a date. For example, if you set the SelectedDateFormat to Long (so that the long form of the date is displayed) and then enter “1/10/13″ when in the U.S., the date is interpreted as January 10, 2013. This is because the normal short date format is month/day/year. (Note that SelectedDateFormat only dictates how the date is displayed–you can still enter it using the short format). However, if you enter “1/10/13″ and your regional settings are set to French/France, the date will be interpreted as October 1, 2013. A Practical Quick-start Tutorial on MVVM in WPF.

Introduction Imagine you want to create an application with a unique design.
All your buttons should have an orange background and an italic font. Doing this the conventional way means that you have to set the Background and the FontStyle property on every single button. <StackPanel Orientation="Horizontal" VerticalAlignment="Top"><Button Background="Orange" FontStyle="Italic" Padding="8,4" Margin="4">Styles</Button><Button Background="Orange" FontStyle="Italic" Padding="8,4" Margin="4">are</Button><Button Background="Orange" FontStyle="Italic" Padding="8,4" Margin="4">cool</Button></StackPanel> This code is neither maintainable nor short and clear.
