Sorting data in the Windows Forms DataGridView control
By default, users can sort the data in a DataGridView control by clicking the header of a text box column (or by pressing F3 when a text box cell is focused on .NET Framework 4.7.2 and later versions). You can modify the SortMode property of specific columns to allow users to sort by other column types when it makes sense to do so. You can also sort the data programmatically by any column, or by multiple columns.
