+Summary: Controls.Clear() prevents re-adding controls
+
+Description of Problem:
+After clearing controls from a ControlCollection using
+ControlCollection.Clear(), new controls can be added, but the cleared ones
+cannot be added again.
+
+Steps to reproduce the problem:
+I have included a tar file with a very simple web site that produces the
+problem.
+1. Put a PlaceHolder control on a web form.
+2. In the code-behind file, create a LiteralControl with some text and add
+it to the PlaceHolder.Controls collection using 
+LiteralControl test = new LiteralControl("HEY");
+PlaceHolder1.Controls.Add(test);
+3. Clear the collection
+PlaceHolder1.Controls.Clear();
+4. Add it again:
+PlaceHolder1.Controls.Add(test);
+5. But the control does NOT get added.  In fact, after step 4, 
+PlaceHolder1.Controls.Count == 0 
+
+Actual Results:
+Control does not get added the second time, and at run time the web page
+does NOT display the control.
+
+Expected Results:
+The control to be there at first, then get removed at the Clear() method,
+then get added again and display on the web page at runtime.
+
+How often does this happen? 
+Every time.
+
+Additional Information:
+I will attach a very small test case.
