Focus on DataGridCell for SelectedItem when DataGrid Receives Keyboard Focus

Question

I have a DataGrid where the SelectedItem is bound to a VM Selected property. I have a search control that will do a find and the SelectedItem

The FocusManager solution didn't work for me for some reason. Also I required a more general apporach. So here is, what I came up with:

using System.Windows.Controls;

public static void RestoreFocus(this DataGrid dataGrid,
                                     int column = 0, bool scrollIntoView = false)
{
    if (dataGrid.IsKeyboardFocusWithin && dataGrid.SelectedItem != null)
    {
        // make sure everything is up to date
        dataGrid.UpdateLayout();

        if (scrollIntoView)
        {
            dataGrid.ScrollIntoView(dataGrid.SelectedItem);
        }

        var cellcontent = dataGrid.Columns[column].GetCellContent(dataGrid.SelectedItem);
        var cell = cellcontent?.Parent as DataGridCell;
        if (cell != null)
        {
            cell.Focus();
        }
    }
}

And call it like this:

MyDataGrid.IsKeyboardFocusWithinChanged += (sender, e) =>
{
    if ((bool)e.NewValue == true)
    {
        Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Loaded, new Action(() =>
        {
            MyDataGrid.RestoreFocus(scrollIntoView: true);
        }));
    }
};
