Import text file into datagridview C++

Hello, I want to do when clicking on the button, import the txt document into the DataGridView. How can this be implemented?

Txt document,  fill in this approximate way:

1.txt
0, Name0, Test0, Type0
1, Name1, Test1, Type1

DataGridView consists of 4 columns.

I also wanted to realize that when you click on one of the rows 1 or 2. In the TextBox There is a link to download some file;

My english bad, sorry :)
