+Summary: Form.Controls.Clear() doesn't work
+
+Description of Problem:
+Using mono 1.1.16, Windows XP SP1, the following code does not work (and it
+does using MS.NET). Apparently Form.Controls.Clear() does not do anything.
+When you call the Clear() method right after Add(), it works, but when it's
+called from a button's Click event, it doesn't.
+
+Reproduce code:
+using System;
+using System.Collections.Generic;
+using System.Windows.Forms;
+using System.Drawing;
+
+namespace MonoTest10
+{
+ class Form1 : Form
+ {
+ static void Main()
+ {
+ Application.Run(new Form1());
+ }
+
+ public Form1()
+ {
+ Label L = new Label();
+ L.Text = "hello";
+ this.Controls.Add(L);
+
+ Button B = new Button();
+ B.Top = 150;
+ B.Click += new EventHandler(B_Click);
+ this.Controls.Add(B);
+ }
+
+ void B_Click(object sender, EventArgs e)
+ {
+ this.Controls.Clear();
+ }
+ }
+}
+
+Actual Results:
+When clicking the button, nothing happens.
+
+Expected Results:
+Both the button and the label should disappear.
