>You would have to start the search on a background thread if you want the UI to respond to events while it's running. Normal .NET WinForm apps. have a BackgroundWorker class. I don't think it's available for CF app. Here's an implementation of it that might work for you:

Thanks a lot, I think it's a bit too advanced for now - I better concentrate on getting the main functionality working.

I was able to display the selected item info in the textboxes (even if it is very slow on the device), so the next step is to be able to add this info to the grid view bellow.

The GridView is supposed to display ItemNo, Description (this field doesn't belong to the OrderDetails table), Price, Qty and Total Price.

Do you know how can I add this info? Do I have to add few more columns to my DataSet/TA (for virtual columns)?

Thanks again in advance.
