Why are you trying to convert the value in txtEmpSearchLastName.Text to an int? I'm assuming it is a string. Change your code to:

cmd = "select * from staff where staff.LastName=" txtEmpSearchLastName.Text

basically what i wana do is i want to display all the result of staff table which is searched by last name. but when i use the above code its giving me error. is it possible if you could fix the code. so that it displays all field values into gridview. my data base contains two int values as emp_id and telephone.


And also when i use this code the one you just given me

cmd = "select * from staff where staff.LastName=" txtEmpSearchLastName.Text
it gives me an error.
column name doesnot exist. although i am giving the correct column name and correct value


If it says the column name does not exist then it doesn't. Proper capitalization matters so you will need to check it is not lastName.
