Here is the scenario,

The user enters a purchase order number. When my SearchPO button is clicked, the materials belonging to the entered PO number will be displayed in my grid which includes description, received quantity and amount. When the user enters another PO number and clicks the SearchPO button again, the materials will be displayed again in the grid. In my grid, I will provide a checkbox that the user can check/uncheck to select the materials that he/she will be paying. The grid display will be cleared when my CreatePayable button is clicked.
