Hi,

"String was not recognized as a valid DateTime."

M getting this error on submit button click. my "warranty" column is of text type and "warrantytill" column is of date type in my table. Now i am saving the values according to warranty text value i.e) if warranty.text="yes" take d value from respective textbox. if warranty text="no" then it should save null or nothing.

How do a do that.

Thanks

Hi,

Its Occurred because
given input string for DateTime Conversion is not in right format...

Try this:

C#

SqlParameter WarrantyTillparam = new SqlParameter("@WarantyTill", SqlDbType.Date);
DateTime yourDateTime = DateTime.ParseExact(txtwarrantytill.Text, "yyyyMMdd", CultureInfo.InvariantCulture);
WarrantyTillparam.Value = yourDateTime;
//WarrantyTillparam.Value = txtwarrantytill.Text;  
cmd.Parameters.Add(WarrantyTillparam);
