  • why javascript can not read the cookie in asp.net ?

    - by MemoryLeak
    I want to read the sessionid in cookie which is automatically generated by asp.net. such as ASP.NET_SessionId. but when i use javascript: document.cookie = "ASP.NET_SessionId=;" since i want to set the ASP.NET_SessionId to be empty. but after the javascript executed, i found instead of change the ASP.NET_SessionId to empty, system generate a new cookie with ASP.NET_SessionId equal to empty. why system not modify the cookie but generate a new one ? Thanks!

  • Change panel "visible" property on MasterPage from Child pages

    - by Vitor Reis
    I want to show some panel with a label that is located on a MasterPage from inside it's child pages.. I already did the coding on the MasterPage: public class MyMaster : MasterPage { public void ShowPanel(string pMessage) { labelInside.Text = pMessage; myPanel.visible = true; } } Then I make the calls from child pages: public void ShowPanel(string pMessage) { MyMaster masterPage = this.Master as MyMaster; masterPage.ShowPanel(pMessage); } This "works" ok, but it won't show nothing, since I need the page to be "refreshed" in an "ajax-way" like an UpdatePanel, which I can't use because the Trigger is in another page, right? I really need this to work.. even if you have another completely different way to do this, I would appreciate.

  • Caching asp.net viewdata

    - by Tomh
    Hey guys, I'm currently thinking about caching most of my viewdata excpt user specific data after a user logs on. I thought the simplest way was caching the ViewData object itself and adding the user specific data after it was loaded. Are there any downsides of this approach? Are there better ways? string cacheKey = "Nieuws/show/" + id; if (HttpRuntime.Cache[cacheKey] != null) { ViewData = HttpRuntime.Cache[cacheKey] as ViewDataDictionary; } else { // add stuff to view data HttpRuntime.Cache.Insert(cacheKey, ViewData, null, DateTime.Now.AddSeconds(180), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null); }

  • Application loses authentication when performing redirect to a virtual directory

    - by nuhusky2003
    I have the following setup: http://www.example.com/dir1/ and http://www.example.com/dir2/ Each virtual directory is configured on IIS6.0 as an application with own AppPool. When redirecting authenticated user from dir1 to dir2 using response.redirect I lose authentication information for the user and the user is being redirected to the login page. This issue was not coming up with each app (dir1 and dir2) were configured under subdomain, ex: http://dir1.example.com and http://dir2.example.com. I have resolved the issue by adding a machine key to the machine.config file. Can someone explain to me why it's not working on a http://www.example.com/dir1 configuration?

  • Membership.Updateuser not really updating the database.

    - by Shimrod
    Hi everybody, I'm currently working on a membership system for my web application, which is based on forms authentication from the framework. I created some users with the integrated tool, and the login is perfectly working. But now what I want to do is to give administrator the capability to create, modify, delete users. So here is what I've got right now: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim muc As MembershipUserCollection = Membership.GetAllUsers() ComboBox1.DataSource = muc ComboBox1.DataValueField = "UserName" ComboBox1.DataTextField = "UserName" ComboBox1.DataBind() End Sub Protected Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ComboBox1.SelectedIndexChanged Dim userName As String = ComboBox1.SelectedValue Dim mu As MembershipUser = Membership.GetUser(userName) Dim userRoles As String() = Roles.GetRolesForUser(userName) tbComments.Text = mu.Comment tbEmail.Text = mu.Email lblUserName.Text = mu.UserName End Sub Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click Dim userName As String = ComboBox1.SelectedValue Dim mu As MembershipUser = Membership.GetUser(userName) If Not mu Is Nothing Then Try mu.Comment = tbComments.Text Membership.UpdateUser(mu) mu.Email = tbEmail.Text Membership.UpdateUser(mu) mu.IsApproved = True Membership.UpdateUser(mu) mu = Nothing Catch ex As Exception Console.WriteLine(ex.ToString()) End Try End If DetailPanel.Visible = False End Sub The problem is that the record doesn't seem to be updated in the database. I made the multiple calls to Membership.UpdateUser after reading this blog entry, but it didn't change anything. A strange think I noticed while debugging, is that when I enter the Button1_Click method, Membership.GetUser(userName) returns me values from my precedent attempt ! I don't really understand what I'm missing. Does someone have a clue ? Thanks in advance !

  • Authenticating to multiple OUs in Active Directory

    - by Jaxidian
    I'm using the Active Directory Membership Provider with the following configuration: <connectionStrings> <add name="MyConnString" connectionString="LDAP://domaincontroller/OU=Product Users,DC=my,DC=domain,DC=com" /> </connectionStrings> <membership defaultProvider="MyProvider"> <providers> <clear /> <add name="MyProvider" connectionStringName="MyConnString" connectionUsername="my.domain.com\service_account" connectionPassword="biguglypassword" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> This works perfectly except it requires ALL of my users to be in the "Product Users" OU when I would actually like to have all of my users organized into various child OUs under our "Product Users" OU. Is this possible? (Note that this is a partial repost of this question but the question I'm asking here was never answered there.)

  • ASP.NET client side validation with dataannotations - javascript minimumlength zero

    - by Kordonme
    Hi! I'm doing client side validation on a project I'm working on. Everything works, except for the minimumlength property of the StringLength attribute (it works when submitting and a serverside validation is done): [StringLength(50, MinimumLength = 6)] The javascript generated by Html.EnableClientValication(); is the following: // snip {"FieldName":"User.Password","ReplaceValidationMessageContents":true,"ValidationMessageId":"User_Password_validationMessage","ValidationRules":[{"ErrorMessage":"The field Password must be a string with a minimum length of 6 and a maximum length of 50.","ValidationParameters":{"minimumLength":0,"maximumLength":50},"ValidationType":"stringLength"}]}],"FormId":"form0","ReplaceValidationSummary":false}) The important thing is here: {"minimumLength":0,"maximumLength":50} It produces javascript with the wrong minimumproperty. You guys have a hint? Is this a possible bug?

  • Membership.ValidateUser always returns false after upgrade to VS 2010 / .NET 4.0

    - by nw
    Not sure whether this pertains to VS 2010 or to the upgraded framework, but... we are using the Oracle membership provider to authenticate users. Prior to the upgrade everything worked fine, but now Membership.ValidateUser(user, password) returns false despite valid credentials. There is no exception thrown, so it's hard to determine what the problem might be. The website administration tool in VS 2010 is still able to manage users and roles (more or less), so I have no reason to question connectivity. What might the problem be?

  • Applying css media=print not working with MasterPages after pagebreaks

    - by Claudia
    Hi, I´m using a css media=print file in a Page that is using a MasterPage. I put some pagebreaks like this in certain parts of the html code: <h1 style="page-break-before: always; height: 0px; line-height: 0px;"> This works perfectly in the first page, meaning that the styles are applied correctly, but after the pagebreaks, the css is not working any more. Looking somewhere, the advice was to delete the masterpage, and yeah, it worked, but it is not the best thing to do, ´cause I have to remember changing this page if the masterpage changes. Anyone knows another way to solve this problem using MasterPages?

    This is how I login ('user' holds the data of the user): HttpResponse Response = HttpContext.Current.Response; HttpRequest Request = HttpContext.Current.Request; FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, user.UserId.ToString(), DateTime.Now, DateTime.Now.AddHours(12), false, UserResolver.Serialize(user)); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(ticket)); cookie.Path = FormsAuthentication.FormsCookiePath; Response.Cookies.Add(cookie); string redirectUrl = user.HomePage; Response.Redirect(redirectUrl); After this login I get IsAuthenticated == false. Why?? It worked for me before an hour but I don't know what is wrong now.

  • Accessing Session and IPrinciple data in a Master View in Asp.Net MCV

    - by bplus
    I currently have a abstract controller class that I all my controllers inherit from. In my master page I want to be able to access some data that will be in Session and also the currently user (IPrinciple). I read that I could use the contructor of by abstract base controller class, that is I could do something like public BaseController() { ViewData["SomeData"] = Session["SomeData"]; ViewData["UserName"] = this.User.Identity.Name; } I could then access ViewData["UserName"] etc from my master page. My problem is that both Session and User are null at this point. Does anybody know of a different approach? Thanks in advance.
