BeforeCaptionShowEventHandler Delegate

Represents the method that will handle the BeforeCaptionShow event of an Action.

Namespace:  Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)

Syntax

'Declaration
Public Delegate Sub BeforeCaptionShowEventHandler ( _
    sender As Object, _
    e As ActionEventArgs _
)

public delegate void BeforeCaptionShowEventHandler(
    Object sender,
    ActionEventArgs e
)

Parameters

• sender
  Type: System.Object
  The source of the event.

• e
  Type: Microsoft.Office.Tools.Excel.ActionEventArgs
  An ActionEventArgs that contains the event data.

Remarks

When you create a BeforeCaptionShowEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about delegates, see Events and Delegates.

Examples

The following code example creates a smart tag that recognizes two terms and offers one action. It then adds event handlers for the events BeforeCaptionShow and Click. To test the code, type the word "term" in one cell and the word "recognize" in another cell, and then try the smart tag actions.

This example is for a document-level customization.
