Order of controls in a form's Control property in C#

Question

I am having a peculiar problem with the order in which FlowLayoutPanels are added in to the form\'s controls property. This is what I tried,

What if in future some other designer removed the controls, added back etc? Checking the designer always is a mess. What would be better is to sort the controls in the container control before you enumerate. I use this extension method (if you have Linq):

public static List ToControlsSorted(this Control panel)
{
    var controls = panel.Controls.OfType().ToList();
    controls.Sort((c1, c2) => c1.TabIndex.CompareTo(c2.TabIndex));
    return controls;
}

And you can:

foreach (FlowLayoutPanel aDaysControl in this.ToControlsSorted())
{
    MessageBox.Show(aDaysControl.TabIndex.ToString());
}

(Above is for TabIndex). Would be trivial to sort according to Tag from that.
