How to set the drop down property?

I set the editortype in codebehind

.EditorType =  typeof(XamDateTimeEditor);

So how to set the property???

What I want (which I think is the same thing others have asked for):

Given a xamDataGrid with a column of Date or DateTime data, I want to click on one of the date cells, and have a calendar pop-up appear.  

What is happening (using eval 9.1):   There is no popup. So the date field looks says something like "04/05/2009".  I take it that the in-cell control (the control that displays the date formatting, with the fields separated by forward slashes)  is xamDateTimeEditor.

I see from the Editors.pdf document that there is a calendar control  (xamMonthCalendar)  but I can't tell whether that calendar control can be used within a xamDataGrid.   The examples in Editors.pdf appear to be adding the xamMonthCalendar  directly onto a form, but I want it to pop up when I edit a date cell in a data grid. 

Since you mentioned the XamFeatureBrowser, I looked through it.  I do not see any examples of pop-up calendar. 

Thanks for any help!  

p.s.  I probably should have mentioned:  I'm doing an evaluation, and I have Infragistics3.Wpf.v9.1.Express

-- is the xamMonthCalendar control even included in the 9.1.Express ?  Or should I have downloaded that other, more complete eval package if I want to use the XamMonthCalendar?

Hello,

If you are evaluating our product you should really download and install the trial version. In contrast to the Express, the trial has the full functionality and all of the controls in it.

Hi,

Yes, I did already download the trial version, earlier today.  

My follow-up question, asking about Times not showing up when I use the calendar pop-up,  was posted after I replaced the express install with the trial install.
