  InfoPath provides the SwitchView method to allow you to programmatically switch views from within your code.

• Prevent Field Validation From Occurring OnLoad

  The OnValidate event fires for each field in your main DOM before the OnLoad event is fired.

• Switch Views via Code and Rules

  There will be times when you will want to switch views during unsupported events, such as the OnAfterChange event.

• Order of Processing at OnClick

  In InfoPath, the order of processing when a user clicks a button is: Rules Code When you write your OnClick event handler, take into account that any rules associated with the button will be processed before the code is reached. This can be very useful... Posted Jul 15 2004, 10:00 AM by Greg Collins with | with no comments Filed under: Rules, Code, Buttons, OnClick

• Populate a Drop-Down List Box via Code

  NOTE: This article was written for the original InfoPath 2003, which did not support secondary data sources.

• Avoid an Endless Loop During Event Bubbling

  Event bubbling means that when an event, such as the OnAfterChange event, happens on a particular data node in an XML tree, that event is passed up to the parent node, and then the grandparent node, and so on, all the way back to the root node. Thus the... Posted Jul 07 2004, 08:04 PM by Greg Collins with | with no comments Filed under: Code, Events
