Multiple updates with Ajax

I have two dropdownboxes, one that is dependent on the other for the value. I have these dropdown boxes in an update panel using a sqldatasource on both of them. The second dropdown box uses the selected value from the first dropdown box to populate its content. I also have two text boxes that are start and end dates that are based on the second dropdown box. For further clarification, I have a publication dropdown box that will populate the issue dropdown box with a listing of all issues for that publication and also will populate the start and end dates for that issue. However, when I select a different publication and the issue is on another month, the issue then is updated but not the start and end dates. How would I go about accomplishing this?

Can you post the ASPX, or explain how you have this set up? Are the textboxes inside of the updatepanel? Do you have the textboxes in a separate updatepanel that has a trigger set? Are you updating the textbox values in the page_load event? You should try stepping through your code, and ensure that the code responsible for setting the text in the textboxes is actually being reached. If it is, verify that the textboxes are inside of an update panel. Control outside of the updatepanel can not be udpated asynchronously (unless insdie of another updatepanel).
