VS 2010 Accessing Same Form But For Different Actions?

I have a datagridview on a form and this shows up my list of suppliers. I have a textbox which when i click shows up the supplier list and from there when i double click on a row, the supplier's name is shown in the textbox. The thing is i have to do same on the same page for search purposes which got its own textbox. But the cell double-click event already contains code that will display it in some other textbox like i mentioned previously. What i thought is to make another form with a datagridview. So this datagridview will be used to display the supplier's name in search textbox. But what if i have to access this form several times. Do i have to create several forms everytime?
