Perhaps because you called lstState.RemoveAt(0); just prior to calling Insert?

I'm not sure I understand your question. Are you saying that your UI element should be displaying "--Select--" as the first item but is displaying "All States" and that you are expecting that "All States" should be the second element being displayed? If so, maybe you need to call an Update() command of some sort. It is a bit difficult to know for sure since you have not been very precise in the definition of your issue.

Can you look at the contents of the List<> in a debugger and, if so, does it contain the information in the expected order? If so then the problem is a failure of the UI element to recognize that its data source has been changed. If so then it may be that your UI element requires explicit notification of a data change, has not been enabled to react automatically or is improperly or incompletely bound.

lstState.RemoveAt(0); is call before calling Insert.
