我有這個類，它給了我「的ScriptManager未聲明」的ScriptManager未聲明 - 錯誤消息
Public NotInheritable Class ResponseHelper
Private Sub New()
End Sub
Public Shared Sub Redirect(ByVal response As HttpResponse, ByVal url As String, ByVal target As String, ByVal windowFeatures As String)
If ([String].IsNullOrEmpty(target) OrElse target.Equals("_self", StringComparison.OrdinalIgnoreCase)) AndAlso [String].IsNullOrEmpty(windowFeatures) Then
response.Redirect(url)
Else
Dim page As Page = DirectCast(HttpContext.Current.Handler, Page)
If page Is Nothing Then
Throw New InvalidOperationException("Cannot redirect to new window outside Page context.")
End If
url = page.ResolveClientUrl(url)
Dim script As String
If Not [String].IsNullOrEmpty(windowFeatures) Then
script = "window.open(""{0}"", ""{1}"", ""{2}"");"
Else
script = "window.open(""{0}"", ""{1}"");"
End If
script = [String].Format(script, url, target, windowFeatures)
ScriptManager.RegisterStartupScript(page, GetType(Page), "Redirect", script, True)
End If
End Sub

此代碼從這個鏈接錯誤名稱：
http://weblogs.asp.net/infinitiesloop/archive/2007/09/25/response-redirect-into-a-new-window-with-extension-methods.aspx
我已經8個小時試圖找出如何打開一個新頁面並向其發送參數。並發現這個代碼，並試圖應用6小時，但沒有。
感謝。
