命名空间： Microsoft.Office.Tools.Excel
程序集： Microsoft.Office.Tools.Excel.v9.0（在 Microsoft.Office.Tools.Excel.v9.0.dll 中）

语法

声明
Public Event SelectionChange As DocEvents_SelectionChangeEventHandler
用法
Dim instance As ListObject
Dim handler As DocEvents_SelectionChangeEventHandler

AddHandler instance.SelectionChange, handler

public event DocEvents_SelectionChangeEventHandler SelectionChange

备注

当 ListObject 中的任何选定范围发生更改时，将引发此事件。

当将焦点从 ListObject 控件内部移到 ListObject 控件外部时，不引发此事件。当将焦点从 ListObject 控件外部移到 ListObject 控件时，将引发此事件。

示例

下面的代码示例创建一个 ListObject，然后为 SelectionChange 事件创建事件处理程序。若要测试此事件处理程序，请在 ListObject 中选择一个单元格，然后在 ListObject 中选择另一个单元格。

此版本针对的是文档级自定义项。

WithEvents SelectionChangeList As Microsoft.Office.Tools.Excel.ListObject
Private Sub ListObject_SelectionChange()
    SelectionChangeList = Me.Controls.AddListObject( _
        Me.Range("A1", "C4"), "SelectionChangeList")
End Sub


Sub List1_SelectionChange(ByVal Target As _
    Microsoft.Office.Interop.Excel.Range) _
    Handles SelectionChangeList.SelectionChange
    MessageBox.Show("The selection in the list object has changed.")
End Sub

private void ListObject_SelectionChange()
{
    Microsoft.Office.Tools.Excel.ListObject list1 =
        this.Controls.AddListObject(
        this.Range["A1", "C4"], "list1");
    list1.SelectionChange += new Microsoft.Office.Interop.
        Excel.DocEvents_SelectionChangeEventHandler(
        list1_SelectionChange);
}

void list1_SelectionChange(Microsoft.Office.Interop.Excel.Range Target)
{
    MessageBox.Show("The selection in the list object has changed.");
}

此版本针对的是应用程序级外接程序。

WithEvents SelectionChangeList As ListObject
Private Sub ListObject_SelectionChange()
    Dim vstoWorksheet As Worksheet = CType( _
        Me.Application.ActiveWorkbook.Worksheets(1),  _
        Excel.Worksheet).GetVstoObject()
    SelectionChangeList = vstoWorksheet.Controls.AddListObject( _
        vstoWorksheet.Range("A1", "C4"), "SelectionChangeList")
End Sub


Sub List1_SelectionChange(ByVal Target As  _
    Microsoft.Office.Interop.Excel.Range) _
    Handles SelectionChangeList.SelectionChange
    System.Windows.Forms.MessageBox.Show( _
        "The selection in the list object has changed.")
End Sub

private void ListObject_SelectionChange()
{
    Worksheet vstoWorksheet = ((Excel.Worksheet)
        this.Application.ActiveWorkbook.Worksheets[1]).GetVstoObject();
    ListObject list1 =
        vstoWorksheet.Controls.AddListObject(
        vstoWorksheet.Range["A1", "C4"], "list1");
    list1.SelectionChange += new 
        Excel.DocEvents_SelectionChangeEventHandler(
        list1_SelectionChange);
}

void list1_SelectionChange(Excel.Range Target)
{
    System.Windows.Forms.MessageBox.Show("The selection in the list object has changed.");
}
