If you have a DataTable, and you want to display the content in a DataGridView, it tends to be best to set any sorting and filtering via the DataTable's DefaultView, and then display the content of that DefaultView in the DataGridView.

Do you mean:
Sorting data in DataGridView control - Windows Forms .NET Framework | Microsoft Docs[^]
DataGridView.Sort Method (System.Windows.Forms) | Microsoft Docs[^]
If not, you are going to have to be a lot more specific about what you are trying to achieve and why it's a problem for you.

I want to add drag and drop feature. Where user can drag any row and drop where he wants. So in this way he can reorder the data.

If it wasn't databound then it's fairly easy by the look of things:
shows the code.

But data bound is more complicated: you will hee to use much the same code, to identify where the data to move comes from and where it is to go, and then manually rearrange the rows in the bound data source.
That's a relatively complicated job, particularly when you have multiple row selections!

What I did using a music track List (without the drag and drop, but with "up", "down", "To Top", and "To Bottom" buttons) was to remove all the selected tracks to a new list, then locate the position to put them and Insert them all there.
The same approach should work for all data collections.
