[CLOSED] Local datastore filtering param when getting data to combo in local mode
Hi,
I would like to query a local datastore in a combo, with a "hidden" parameter.
If you take this very much simplified example below:
Before the combo is populated, i would like to pass a "TypeID=1" filter parameter, so the combo is only populated with the first 3 records, without having to repopulate the datastore.
Can you help me in the right direction?
