在WPF中,如何确定控件所在的网格中的列/行？

int column = Grid.GetColumn(control);
int row = Grid.GetRow(control);

Grid parentGrid = control.Parent as Grid;
int column = Grid.GetColumn(control);
int row = Grid.GetRow(control);

DependencyObject parent = VisualTreeHelper.GetParent(control);
while (parent != null && !(parent is Grid))
{
    parent = VisualTreeHelper.GetParent(parent);
}

if (parent != null)
{
    Grid parentGrid = parent as Grid;
    int column = Grid.GetColumn(control);
    int row = Grid.GetRow(control);
}
