I have been using the DropDownList control within ASP.NET quite happily 
within my application. I am using Vb edition. However, I am now inserting 
some 150 items into a dropdownlist control. My problem is that when the 
user selects item number 150 for example, the SelectIndexChange event is 
fired, the value though that I wish to capture from the control is not the 
one the user has selected (150). It works perfectly providing the user 
makes a selection within the top 40 or so entries.

Is the control caching the values / paging them? Do i need to set another 
property on the control to allow an accurate return of the selected item? 
Is there a .NET patch that may fix the problem (if its not a code issue)
