通过

NamedRange.Change 事件

  • 项目

当 NamedRange 控件中发生更改时发生。

命名空间：  Microsoft.Office.Tools.Excel
程序集：  Microsoft.Office.Tools.Excel（在 Microsoft.Office.Tools.Excel.dll 中）

语法

声明
Event Change As DocEvents_ChangeEventHandler

event DocEvents_ChangeEventHandler Change

备注

如果通过编程修改或用户交互更改 NamedRange 控件，则将引发此事件。 当 NamedRange 控件中的单元格在重新计算过程中发生更改时，不会发生此事件。

示例

下面的代码示例创建一个 NamedRange 和一个 Change 事件处理程序。 若要引发 Change 事件，请向 NamedRange 中的某个单元格添加文本，然后按 Enter。

此版本针对的是文档级自定义项。

Private changesRange As Microsoft.Office.Tools.Excel.NamedRange

Private Sub NotifyChanges()
    changesRange = Me.Controls.AddNamedRange( _
        Me.Range("B2", "E5"), "compositeRange")
    AddHandler changesRange.Change, _
        AddressOf changesRange_Change
End Sub


Sub changesRange_Change(ByVal Target As Excel.Range)
    Dim cellAddress As String = Target.Address(, , _
        Microsoft.Office.Interop.Excel.XlReferenceStyle.xlA1, , )
    MessageBox.Show("Cell " & cellAddress & " changed.")
End Sub

Microsoft.Office.Tools.Excel.NamedRange changesRange;
private void NotifyChanges()
{
    changesRange = this.Controls.AddNamedRange(
        this.Range["B2", "E5"], "compositeRange");
    changesRange.Change += new Microsoft.Office.Interop.Excel.
        DocEvents_ChangeEventHandler(changesRange_Change);
}

void changesRange_Change(Excel.Range Target)
{
    string cellAddress = Target.get_Address(missing, missing, 
        Microsoft.Office.Interop.Excel.XlReferenceStyle.xlA1,
        missing, missing);
    MessageBox.Show("Cell " + cellAddress + " changed.");
}

此版本针对的是应用程序级外接程序。

Private changesRange As NamedRange

Private Sub NotifyChanges()

    Dim NativeWorksheet As Microsoft.Office.Interop.Excel.Worksheet =
        Globals.ThisAddIn.Application.ActiveSheet

    Dim vstoWorksheet As Microsoft.Office.Tools.Excel.Worksheet =
            Globals.Factory.GetVstoObject(NativeWorksheet)

    changesRange = vstoWorksheet.Controls.AddNamedRange( _
        vstoWorksheet.Range("B2", "E5"), "compositeRange")
    AddHandler changesRange.Change, _
        AddressOf changesRange_Change
End Sub


Sub changesRange_Change(ByVal Target As Excel.Range)
    Dim cellAddress As String = Target.Address(, , _
        Excel.XlReferenceStyle.xlA1, , )
    System.Windows.Forms.MessageBox.Show("Cell " & cellAddress & " changed.")
End Sub

NamedRange changesRange;
private void NotifyChanges()
{
    Worksheet vstoWorksheet =
        Globals.Factory.GetVstoObject(this.Application.ActiveWorkbook.Worksheets[1]);
    changesRange = vstoWorksheet.Controls.AddNamedRange(
        vstoWorksheet.Range["B2", "E5"], "compositeRange");
    changesRange.Change += new Excel.DocEvents_ChangeEventHandler(
        changesRange_Change);
}

void changesRange_Change(Excel.Range Target)
{
    string cellAddress = Target.get_Address(missing, missing,
        Excel.XlReferenceStyle.xlA1,
        missing, missing);
    System.Windows.Forms.MessageBox.Show("Cell " + cellAddress +
