This is the project that we created together in the June 2023 ASNA Web class. It is based on the avr-asp-net-05-gridview project with one major exception: The avr-asp-net-05-gridview gridview project uses the app_code/CustomerByNameList class to partition away the file IO logic from the ASPX page's code behind.
Most of the customer's existing in-house projects have the file IO inline in the ASPX page code behind. avr-asp-net-05-gridview that we did together more represents the customer's existing code.
