• The InfoPath 2003 form events are OnLoad , OnClick , OnSwitchView , OnSubmitRequest , OnVersionUpgrade , and OnAfterImport .

• The OnLoad event occurs after a form has been loaded, but before the default view has been displayed.

• The OnClick event is available only on button form controls and provides a way to script in response to a user -initiated click on a button form control.

• The OnSwitchView event occurs when a user switches between the views of a form.

• The OnSubmitRequest event occurs when a user chooses to submit a form or programmatically using XDocument.Submit() .

• The OnVersionUpgrade event occurs when there is a mismatch between the version number of a form and the corresponding form template.

• The OnAfterImport event occurs when a number of forms have been merged.

• The InfoPath 2003 validation events are OnBeforeChange , OnValidate , and OnAfterChange .

• The OnBeforeChange event occurs after a value has been entered in a form control and the user has moved away from the form control, but before the new value is validated .
