Public Class Form1

        Dim selectedItems As DataGridViewSelectedRowCollection = DataGridView1.SelectedRows
        Debug.Print(DataGridView1.CurrentRow.Index)

A quick and dirty way of sorting anything in winforms applicataions is to add a listbnx, set visible=false and sorted=true, add the items to that, and let it sort them for you - then just read them back in order.

Create some data type which carries the data relevant to sorting (it could be the Value of just one columns, or something else, depending on your sorting criteria) plus — importantly — the index in the grid view at the moment.

Collect all instances of this data type from the grid view and put all these instances in the instance of the list System.Collections.Generic.List<T>, where T should be this data type:

Then sort this list using your comparison criteria:
