我有这个类，它给了我“的ScriptManager未声明”的ScriptManager未声明 - 错误消息
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
末级
此代码从这个链接错误名称：
http://weblogs.asp.net/infinitiesloop/archive/2007/09/25/response-redirect-into-a-new-window-with-extension-methods.aspx
我已经8个小时试图找出如何打开一个新页面并向其发送参数。并发现这个代码，并试图应用6小时，但没有。
感谢。
