Question

I would like to Know whether this is a dataset, datagridview or list view and also would like to know how to make on like this

Answer 1

DataSet => The data that you use to attach to the grid. Will itself contain a collection of DataTable

DataGridView => The control that shows the data. Is effectively a collection of column templates, and using those will marry up to the DataTable or DataSet you set as the DataSource to the control.

ListView => These are the repeater controls you can use like a drop down list, they display elements of a collection via a template for each item, allowing the user to select/focus an item or multiples thereof.

To make one like the one you showed, you can use WinForms, which is probably the easiest to learn too! There's a million resources on the internet for this, Google is your friend, and I'll give you a headstart here.

To directly answer your first question, it's actually ALL THREE of those things!
