Zones: Microsoft Visual Studio Express, .Net Editors & IDEs, .NET Framework 3.x versions

Tags: vb.net 3.5, ie 7, System.FormatException: String was not recognized as a valid DateTime.

I am using vs WebDeveloper, .net3.5, sql server express. I have a table that has a date time column, STARTDATE. After I select the date, then try to insert the record I get the error listed. This is my line of code for that particular field

         
             <ew:CalendarPopup ID="start_dateTextBox" runat="server"
                                Text='<%# Bind("start_date") %>' />

A request has been made to change the grade; The expert feels the current grade does not fit the criteria of the intended guidelines. Those guidelines can been seen at http:/help.jsp#hi73 If there is no response in 4 days, I will review this question and grade accordingly.
Thank you.
