WorkbookBase.BeforeSave Event
Occurs before the workbook is saved.
Namespace: Microsoft.Office.Tools.Excel
Assembly: Microsoft.Office.Tools.Excel.v4.0.Utilities (in Microsoft.Office.Tools.Excel.v4.0.Utilities.dll)
Syntax
'Declaration
Public Event BeforeSave As WorkbookEvents_BeforeSaveEventHandler
public event WorkbookEvents_BeforeSaveEventHandler BeforeSave
Examples
The following code example demonstrates a handler for the BeforeSave event. The event handler prompts the user to either continue with the save operation or cancel it. If the user cancels the save operation, then the Cancel parameter of the WorkbookEvents_BeforeSaveEventHandler event handler is set to true so that Microsoft Office Excel does not save the workbook.
This example is for a document-level customization.
Sub ThisWorkbook_BeforeSave(ByVal SaveAsUI As Boolean, _
ByRef Cancel As Boolean) Handles Me.BeforeSave
If DialogResult.No = MessageBox.Show("Are you sure " & _
"you want to save the workbook?", "Sample", _
MessageBoxButtons.YesNo) Then
Cancel = True
MessageBox.Show("Save is canceled.")
End If
End Sub
private void WorkbookBeforeSave()
{
this.BeforeSave +=
new Excel.WorkbookEvents_BeforeSaveEventHandler(
ThisWorkbook_BeforeSave);
}
void ThisWorkbook_BeforeSave(bool SaveAsUI, ref bool Cancel)
{
if (DialogResult.No == MessageBox.Show("Are you sure you want to " +
"save the workbook?", "Example", MessageBoxButtons.YesNo))
{
Cancel = true;
MessageBox.Show("Save is canceled.");
}
}
