I'm going to use MySQL or SQLite and Entity Framework. I've not used either before. just started reading up on EF yesterday. My reason for a DB rather than a Txt file is that its going to be shared data via the cloud when I finish developing the app. But I might consider doing it with a txt file also.

How can I send you a picture? In the DataGridView there are rows and columns. If the heading on one column is Day of week. this means valid entries in that column are the days of week, Monday, Tuesday... My request is if the user starts to type a day in the cell in the column he will be presented with the possible valued entries which are stored in a database. My application will not have 7 days but more like 50 entries. I don't want the user to have to scroll through all 50 entries. Also the user is free to add addition ad hoc entries.
So if the grid has 10 rows, this means in the column the user needs to enter 10 entries each time looking for the available entries or creating a new one.

I haven't tried any code yet. I have a working DataGridView and a Queue. I want to start the next bit but decided to research it first as I am new to C#, and I'm not aware of its potential yet.

Not quite but close, I want to save the entered note to a database via a Queue. So once the user enters he's/her's notes I send it to the Queue for later processing.
The second part of the question involves another cell in the datagridview, where i want the user to be able to select from a database the appropriate entry, it would be great if the user can start typing and the selection narrows down to the correct entry. Thanks in advance
