Textfieldparser from CSV file - need to put into a datatable or db and show user

Someone showed me textfieldparser, which is working great, I have used it to pull in data from a csv file. I can pull it in a line at a time, but I am looking for some way to pull in all the data into a table and show to the user. Listview? Datagridview? I was using Gridview but it is not available for a windows form. I would like to show this data to the user, let them edit, delete rows, or add, then I will have to send this data to a txt file. Trying to find a good way to do this and possibly make it look decent. Thanks for any help in advance! I have been googling for hours trying to find good methods.

you can use a textfield parser to populate a datagridview.
show us some code that you have (and the source data file if possible)

Also, what do you mean that the datagridview is not available for a windows form?

I was referring to the ASP.NET Gridview which gives you options to change the template(easy to make it look better) - I couldn't find anything equivalent to that in Windows Form.

I have attached the code I was working with thanks to another person on here. Just need to stream it into a datagridview if that is the best way to work with the data. Thanks again for the help!

That works great! I am working on a button for the user to hit once they are done editing to send all of the datagridview to a text file with commas between fields now.
