When using a ClientDataSource to populate a couple of drop downs I have a routine in the first one that on selected item changing it triggers the second one to update.
The issue I have is that if you change the first one again it doesn't update the second drop down, tracing it, it seems that it doesn't actually do anything with the clientdatasource even though the itemsrequested event fires once it is done (doing nothing!).
I am using the following code to trigger the update on the second combo.
Any suggestions? It is worth noting again that this works the first time, it is on the second update that it doesn't change the drop down.
