Custom checkboxlist control maintaining state issue

I have enhanced the checkboxlist control to have few more properties and the main one being the [READONLY]. But the problem I am habving is as follows : SCENARIO1 for example I have two items in Checkboxlist : Item1 and Item2 and I select both of then I hit the readonly button on my webform which sets the READONLY property to true and dsiplays the two selected values which is exactly what I wanted it to do. But then comes the: SCENARIO 2: If I select(Checked) both the options and disable the control , it disables the control with both the options still checked. Now if I select or programatically make the control readonly or Postback then the control looses it state and does't display any checked items as there are none. What am I doing wrong? Thanks in advance for the time and effort. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
