I have a datagrid control with a list of names that it retrieves from a MySql database. I can search through them until i have one result. I want to be able to Display a groupbox control when the number of results is equal to 1. Also, in the groupbox i have a button that when clicked will delete this user from the server and their information from the mysql table called "employee". when the user is deleted i'll display a confirmation message in a messagebox, and reload the table with the updated list. so far the only two problems i have are showing the groupbox when the results are equal to 1 and deleting the user from the sql server based on the name of the search result
