Question

How can I refactor this so that I dont repeat the same code in each method?

    private void setupTooltip(Grid obj)
    {
        var controls = obj.Children.OfType<System.Windows.Controls.TextBox>();
        foreach (var control in controls)
        {
            control.ToolTip = "Code is <" + control.Name + ">";
        }
    }

    private void setupTooltip(StackPanel obj)
    {
        var controls = obj.Children.OfType<System.Windows.Controls.TextBox>();
        foreach (var control in controls)
        {
            control.ToolTip = "Code is <" + control.Name + ">";
        }
    }

Answer 1

Make one method that takes in a Panel object. Both StackPanel and Grid inherit from there, and you don’t look to be using any control specific methods.
