DateOfBirth = DateTime.ParseExact(txtEmpDtofBirth.Text, "MM/dd/yyyy", CultureInfo.InvariantCulture).ToString();

The Below code isn't working actually....
string DateOfBirth = "";

if (txtEmpDtofBirth.Text.Trim().Length > 0)
{
DateOfBirth = DateTime.ParseExact(txtEmpDtofBirth.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture).ToString();

}
else
{
ScriptManager.RegisterStartupScript(this, GetType(), "showlalert", "alert('Invalid Joining Date');", true);
