Nov 9, 2011Im sure this is a very simple and easy to answer question but I've been looking at this too long and being new to ASP I cant seem to find a solution that works.
I have an ASP calendar extender, I click it and the calendar displays as expected, the selected date appears in the textbox, but when the page then posts back I cant get the selected date value from either the textbox.text or the calendarextender.selecteddate properties, I tested this by trying to assign these values to a string variable in the page_load event.
