"The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar." means that the string value that you are passing an invalid datetime string to the Date.Parse() method. The only way that I could reproduce that specific error message is with an invalid time component.

ie: "2/3/2013 30:00" - hours cannot be greater then 23.

Verify what you retrieving from the datareader (dr("something")).

Select Date from Database:
First check the current date format like below:

C#

lblMsg.Text = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern;
if (lblMsg.Text == "dd/MM/yyyy")
  txtd.Text = DateTime.Parse(dr["EventDate"].ToString()).ToString("dd/MM/yyyy");
else
  txtd.Text = DateTime.Parse(dr["EventDate"].ToString()).ToString("MM/dd/yyyy");

Add or Update: Similarly you can check either the current date format is dd/MM/yyyy OR "MM/dd/yyyy"

C#

if (lblMsg.Text == "dd/MM/yyyy")
 usinfo.BDate = DateTime.ParseExact(txtDOB.Text.ToString(), "dd/MM/yyyy", CultureInfo.InvariantCulture);
else
usinfo.BDate = DateTime.ParseExact(txtDOB.Text.ToString(), "MM/dd/yyyy", CultureInfo.InvariantCulture);

lblMsg.Text = "";
