I have created a VB web form with 2 Ajax combobox controls that use the same object data source consisting of a collection of data from an AS400 system, but they use different data fields from that collection. I also have a button control that when clicked, I want to get data for a specific AS400 record based upon value selected in either combobox. It works if I have only one of the comboboxes on the form, but not if both exist, I get the “cannot display webpage” error. I have tried placing breakpoints in button click event and page load event, but it never reaches them. Anyone have an idea what might cause this issue?
