Hi,

try this:

C#

cmdupd.Parameters.Add(new SqlParameter("@JoinDate", SqlDbType.DateTime));
cmdupd.Parameters["@JoinDate"].Value = DateTime.Today.ToString("YYYYMMDD",CultureInfo.CreateSpecificCulture("en-US"));

for more information read this thread:

It throws the error
"Failed to convert parameter value from a String to a DateTime."

I'm tryng since few days to correct this :(

I think only your last snippet would throw an error like this. Can you please post the content of dtpJoinDate.Text?

It's a date time picker not a textbox actually

Please check the Database Table/SP field (JoinDate) is a DateTime field. I am having a strong feeling that it is not.
