Answer 1

You can hit test for DataGridRow, given mouse position & the Grid.

// Retrieve the coordinate of the mouse position.
Point pt = e.GetPosition((UIElement)sender);

DataGridRow row = null;

// Set up a callback to receive the hit test result enumeration.
VisualTreeHelper.HitTest(myGrid, null,
    new HitTestResultCallback(res => {
       row = res.VisualHit as DataGridRow;
       return row != null ? HitTestResultBehavior.Stop :
         HitTestResultBehavior.Continue;
    }),
    new PointHitTestParameters(pt));

Answer 2

maybe something like this?:

private void DoStuff(object sender, RoutedEventArgs e)
{
    // Get the selected MenuItem
    var menuItem = (MenuItem)sender;

    // Get the ContextMenu for the menuItem
    var ctxtMenu = (ContextMenu)menuItem.Parent;

    // Get the placementTarget of the ContextMenu
    var item = (DataGrid)ctxtMenu.PlacementTarget;

    // Now you can get selected item/cell etc.. and cast it to your object
    // example: 
    //var someObject = (SomeObject)item.SelectedCells[0].Item;

    // rest of code....
}
