+Summary: CheckBoxList bug
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+The selected items on the checkbox list are not shown after toggling 
+enable mode.
+
+Steps to reproduce the problem:
+1. Open the attached aspx file.
+2. Check some items in the CheckBoxList
+3. Click on the button "Disable"
+4. Click on the button "Enable"
+
+Actual Results:
+After clicking on the "Enable" button all the items become unchekced.
+
+Expected Results:
+The checked items before disabling the CheckBoxList should stayed checked.
+
+How often does this happen? 
+Always
+
+Additional Information:
+1. Disable doesn't work at all at "Mozilla" explorer.
+2. I saw that indices are saved but "lost" (null value on LoadViewState 
+   at ListControl).

+At first, the selected indices are Selected.
+After, they are un-selected at IPostBackDataHandler.LoadPostData
+at the CheckBoxList class.

+Fixed the "disabled not working" problem.
+
+The viewstate problem can be considered a "feature" until they fix
+theirs. While fixing another bug sometime ago, I realized that it only
+saves indices under certain circumstances for ListControl derived
+classes. That's why CheckBoxList subcontrols viewstate is not saved.
+
+Thanks!

+Wait wait wait, there are cases that can be treated as "features".
+AdRotator Font for eaxpmle is not influenced by chnaging the font's 
+properties.
+Since AdRotator is not a control that font is suppose to be a 
+commonly used element, I treated this as a policy.
+Our case is completly different, there is no other case that a 
+disabled control loses it's status when it enabled again.
+This one is clearly a bug.
+Why should we wait for MS???

+
+Okay, fixing this involves saving the indices for ListBox and
+CheckBoxList. DropDownList and RadioButtonList do not suffer this problem.
+
+I'll do it now.

+Great!!! 
+BTW, I didn't know that a ListBox suffers from the same problem... 
+(Are you sure? I think my tests seem to work...).
+Maybe we can send the fix to MS (teach them how to do it right... 
+:-) ).

+this one is basically impossible and is really a mozilla bug and it
+makes me want to cry.
