Page.CellChanged Event (Visio)
Occurs after the value changes in a cell in a document.
If you are using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
You can use VBA WithEvents variables to sink the CellChanged event.
For performance considerations, the Document object's event set does not include the CellChanged event. To sink the CellChanged event from a Document object (and the ThisDocument object in a VBA project), you must use the AddAdvise method.
This VBA module shows how to use the CellChanged event to trap changes to a shape's cells.
Private WithEvents vsoApplication As Visio.Application Public Sub CellChanged_Example() Dim vsoShape As Visio.Shape 'Set a module-level variable to trap application-level events. Set vsoApplication = Application 'Draw a shape. Set vsoShape = ActivePage.DrawRectangle(1, 2, 2, 1) 'Change a cell (to trigger a CellChanged event). vsoShape.Cells("Width").Formula = 5 End Sub Private Sub vsoApplication_CellChanged(ByVal vsoCell As IVCell) Debug.Print vsoCell.Shape.Name & " " & vsoCell.Name & " changed to =" & vsoCell.Formula End Sub
