This is my scenario: I have 3 DropDownLists dinamically populated (fron SQL database). When I choose some item in one of these DDL, the items in the other two are filtered by the choosen done in the first one. So, this is not a cascade population, because users can start from what DDL he wants.
The problem is with VERY FAST USER: if someone is very fast to do the second choosen, in a time during which the system hasn't finishd to re-populate the DDL, an error is raised (because, for example, he choose an item that is beeing hided by the filtering operation).
I hope to have explaned my problem, so the question is: how is it possible to "disable" the choosen of DDL items during the pupulation operation?
Very big problem for me... thanks for any kind of help!
