ASP.NET Core with ADO.NET dynamic table - checkbox selection, small edits needed

Job ID: 34008076

Budget: $10 – $30 USD

I am using ASP.NET Core with ADO.NET to generate a dynamic table. The table has checkboxes, bound to a data field, and I would like to have the ability to do multi selection (select 1 or all), and on form post, be able to update the records selected.
