I have a RadDatePicker and a regular button to generate a postback on my page.
My RadDatePicker is configured so that the DisplayDateFormat of the DateInput is "MMMM, yyyy" which shows month and year when the control does not have focus - which is key to the problem described below.
First, I select a date via the picker, say "23/01/2009"... the box properly displays "January, 2009"...
Next I click the button which performs a postback.
Now with our 2010.1.519.35 version of the Telerik.Web.UI.dll nothing special happens: the date stays '23/01/2009'.
However, with our 2011.1.315.40 version the date changes to "05/01/2009". It appears that the display text is being parsed upon postback (so 'January, 2009' becomes 05/01/2009 because it uses 05 from the current date 05/03/2012).
Also, when the RadDatePicker is set to AutoPostBack='true' (or when pressing return inside the date field) this does not affect the date like the button does.
I cannot believe this is intended, is it?
