I'm not sure this is working but here is an idea based on some investigation is made in the DataGrid's source code using Reflector:

1/ create a class which inherits DataGridCellsPanel. This is the Panel that is used internally by the DataGrid in order to arrange the cells

2/ override the BringIndexIntoView method by an empty method (without calling the base method)

3/ set the ItemsPanelTemplate property in your XAML:

It seems that when a MouseDown event occurs, at some point the BringIndexIntoView method of the panel is called to do the auto-scroll. Replacing it with a no-op might do the trick.

I hadn't time to test this solution, please let us know if it's working.
