I have billing application based on C# WPF, Screenshot is here. as you can see there is a datagrid, programmatically binded. this datagrid contains lists of item going to be billed.

So when user reaches "Print memo" part (in stack panel 2) i have to update listed items in stock table and insert entries in sales table and finally print the memo.

I want to know is there any speedy way to so because as user gives print command I have to clear datagrid which holds product lists and start accepting new lists.

if you could provide few code or link, will be really helpful..

thanks.........
