InfoPath form load rules and loading event order

/

 

A strange gotcha in InfoPath concerning which event runs first.

  • Create an InfoPath form, with a field.
  • Create a Form Load rule, that sets this field to 1.
  • Add code behind, and create a Form_Loading event, that sets the same field to 2.

 

In InfoPath rich client form / debugging

  • The result number is 2

In InfoPath browser form

  • The result number is 1

 

Keep this order in mind if you use both Form Load rules as well as Form_Loading event.
