问题 What I want is to bind a string to a textblock or datatrigger (basically some WPF object) and take a part of the string. This string will be delimited.

Obviously this will display the same string so I need some sort

问题 I have this: var dateString = string.Format("{0:dd/MM/yyyy}", date); But dateString is 13.05.2011 instead of 13/05/2011.
