WPF DatePicker multiple dates

Question

I don't quite like a few things in a regular .net 4.0 WPF DatePicker.

• I don't like the default calendar icon that always shows '15'. Is it possible to change that, so it could show the actual selected day?

• Is it possible to choose several days instead of a one, so when you click and calendar opens you could see all those days, and label says something lake 'august 2010' or '8/01/2010 - 8/15/2010'?

You need to create your own ControlTemplate. The easiest way is to take the default template (you can download it from here) and change the parts you want.

That would be much harder, but not impossible... You could try to inherit the existing DatePicker, but I think you will need to create your own control from scratch

Answer 2

Try using the Calendar control for multiple date selections. This control already has the functionality for selecting multiple dates built right into it. However, to make it look like a DatePicker, you'll have to create your own style/template.

This shouldn't be too hard though... you could start off by putting the Calendar inside of a Combobox or Expander, then restyle the ComboBox/Expander to the look you prefer.
