Question

它有一个带有LayoutTemplate，ItemTemplate和EditTemplate的ListView。列表视图只显示一个项目。 ItemTemplate为EditButton，CommandName ='Edit'，单击时触发......

Protected Sub ListView1_ItemEditing(ByVal sender As Object, ByVal e As ListViewEditEventArgs) Handles ListView1.ItemEditing

    ListView1.EditIndex = e.NewEditIndex

    'Create SQL and load result in datatable and bind to listview 
    LoadData(Session("SID"))

End Sub

EditTemplate有一个带有CommandName'Update'的UpdateButton，当点击它时触发......

Protected Sub ListView1_Command(ByVal sender As Object, ByVal e As ListViewCommandEventArgs) Handles ListView1.ItemCommand

    If e.CommandName = "Update" Then

        'Use StringBuilder to build up an UPDATE TSql script
        SqlStr = sb.ToString
        'Execute Update
        ExecuteSQLScript(SqlStr)

    End If

以上作品很棒。我的问题是我现在如何回到ItemTemplate View。我知道我必须使用类似于上述ItemEditing方法工作方式的ItemUpdating方法，但我已经用完了想法...任何帮助表示感谢。我现在所拥有的只是......

 Protected Sub ListView1_Updating(ByVal sender As Object, ByVal e As ListViewUpdateEventArgs) Handles ListView1.ItemUpdating

    'ListView1.ItemIndex = e.ItemIndex  'This does not work

    LoadData(Session("SID"))

End Sub
