Now, i am designing the purchase/sales screens. I am showing the items name, qty, price in a datagrid. From the products table, I am able to select the 'ProductName' by giving it a combobox . I want the ProductSellingPrice also to appear in the next column of the grid.
I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:

Product_ID Product Name:
Topics Table:
Topic_ID Product_ID Topic

I want to get all items from one column of database table to the combobox items.

One particular report has 6 recipients and I have been trying to come up with a way to automatically select these 6 email addresses whenever this one report is selected but I haven't had any luck being the neophyte .Net programmer that I am.
