+Summary: [2.0] RadioButtonList OnSelectedIndexChanged called when it shouldn't be
+
+The attached default.aspx shows a bug where the OnSelectIndexChanged
+handler of RadioButtonList is called after submitting the form by clicking
+a button or another control that submits the form.
+
+To reproduce the bug, please do:
+
+1. Click one of the radio buttons, the form gets auto submitted
+2. Click the "Go fish" button. Observe that the OnSelectedIndexChanged
+event gets generated each time you do that.
+
+#2 should not happen at all for lists with AutoPostBack set, since the auto
+postback resets the control "changed" state. This is precisely how MS.NET
+and  Mono ASP.NET 1.1 work.
+
+It seems the problem lies in the ListControl.SelectedIndex property getter
+- whenever LoadPostData on RadioButtonList is called, SelectedIndex is -1
+and thus need_raise gets set to true for RadioButtonList. I don't know why
+it isn't happening for ASP.NET 1.1, though - the code is the same for both
+versions.
