I've a DataGridView which is working perfectly fine. I use it just to show data.
Now I want ability to select rows by check box and perform an operation for only selected rows on click of a button (this button is out of the grid on the same form). For this purpose, I'm following these steps to add checkbox column to datagridview.
On running the application what is see is I can't check the check box either by mouse click or keyboard. And by its looks I can understand that its not in disabled/readonly state. So whenever I try to click on the checkbox, it changes it's borders normally as an enabled check box does. But finally it is not checking the check box.
