The selected date property is not updated when a user types a date into the textbox area of the control and then clicks a submit button.  The user must tab out of the control in order for the selectedDate property to reflect what was entered.  I could find no property that reliably gets me what was entered. 
I downloaded and update to the 2009 Q2 controls today and the same behavior is present.
This appears to be a bug.  Suggestions? 

Thanks.

Hello Mark,

Sorry for the late response. We have tried to reproduce the described issue but without a success. As an additional the RadDatePicker control may not update the date value due to not correct Date setting in the Textblok. You can also share with us some simple code, including the problem. So we will be able to define the real situation.
Also try downloading the latest internal build and check if the problem is still appearing.

Best wishes,

A clarification:  The condition occurs when the raddatepicker is in an collapsed section of the page that is then made visible in response to some action (e.g. a button click).  In the now visible panel, changing the date value by typing and clicking the update button does not update the selected date.  you have to click the button a second time or you had to tab out of the control before clicking the update button.  For some reason, there is no way for me to upload my sample project.  So here's the xaml and code behind.
