I have an infopath form that has two external datasource
I query the first one from a button to populate a dropdownlist
I then want to choose an item from this dropdown list and press a button which will pass the vaule from this combobox to the second datasource.
how do I set the query field for the secondary datasource on change of the dropdown (this throws a state error when I try it), or is there a better way to do it?
Is there an event that fires on the refresh of a datasource?
