OL97: Click Event Behavior for Standard Controls (231593)

MORE INFORMATION

The Click event is the only event that Outlook supports for controls. However, for some controls, the Click event may not fire if the control is bound to a field, or it may not fire at all.

For additional information about the differences between fields and controls, and how they are typically bound together, please see the following article in the Microsoft Knowledge Base:
If a control is bound to a field, the Click event does not fire. However, either the PropertyChange or the CustomPropertyChange event typically fires because data is changing in the underlying field.

The following table summarizes whether or not the Click event will fire under various circumstances:

                                     PropertyChange or
                                     CustomPropertyChange

   N/A = Not applicable

   (1) These controls must have possible values set in the control
       in order for the Click event to fire.

   (2) Commandbuttons are bound to Outlook dialogs, such as the address
       book dialog, Full Name dialog (contact form), and such, so the
       Click event is not applicable to VBScript.

   (3) The Multipage1_Click event doesn't fire, but the Page1_Click
       event fires when the user clicks in the body of an individual
       page. However, this event does not typically provide useful
       functionality for a solution.

   (4) To use a Spinbutton, you bind the Spinbutton and a Label or Textbox
       control to the same field. The Label or Textbox will then show the
       current value of the SpinButton.
