Your update comand, in a simple form is

Update tblUser set Lastname = ABCDEFG

How do you expect SQL to know what Lastname you want to update?

You need to qualify it

Update tblUser set Lastname = ABCDEFG WHERE USERID = 1234

that will only update the single record.

Also you are better using a querystring like:

Update tblUser set Lastname = @LastName where UserID = @UserID
dc.parameters.addwithvalue("@LastName", textbox1.text)
dc.parameters.addwithvalue("@UserID",1234)
conn1.open
dc.execute...
conn1.close
