Web Forms :: Sequence Order For Page.IsPostBack And User.Identity.IsAuthenticated?
Apr 22, 2010
What is the best sequence order for Page.IsPostBack and User.Identity.IsAuthenticated? From what I have search for, this comes up most common:
If Not Page.IsPostBack Then
If User.Identity.IsAuthenticated Then
~Some kind of code~
End If
End If
Is this considered "best practice" or can the two items - Page.IsPostBack and User.Identity.IsAuthenticated -be split into their own sections so the fuctions of these can be independent of each other?I am trying to troubleshoot a placeholder that disappears from a master page when a content page button is pressed to change the content pages active view (I have a multiview w/ 5 views inside of it).

I am using forms authentication and have an issue with a particular browser using the remember me feature. For various reasons I want to support the opera browser that works with the nintendo dsi. I can use forms authentication with that browser just fine but when I use the remember me (cookie) feature I can get through the login but then calls to User.Identity.IsAuthenticated return false. If I do not check remember me it works fine. Initially I thought the browser didn't support cookies but it does. At least I can go to m.gmail.com and check their version of remember me and it works. I can exit the browser and come back in and m.gmail.com remembers me. Also I don't have problems with remember me on any other browser I have tried.
Is anyone aware of some specific browser issue that doesn't work with asp.net forms authentication? I am using asp.net mvc but I doubt that matters.

I am trying to create a httphandler which will intercept a sample pdf file which we have in our website. The httphandler works fine from within my development machine and even my locally published website that if I just try to connect to the test url: [URL] I will get sent to the invalid access page. So pushing it to our IIS6 machine when I try to go to the URL it serves up the PDF document. context.User.Identity.IsAuthenticated is always showing as true. I'm using forms authentication. below is the code I am using as the handler.
public void ProcessRequest(HttpContext context)
{
if (context.User.Identity.IsAuthenticated)
{
string SampleURL = context.Request.AppRelativeCurrentExecutionFilePath;
context.Response.Buffer = true;
context.Response.Clear();
using (FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(SampleURL),FileMode.Open))
{
int length = (int)fs.Length;
byte[] buffer;
using (BinaryReader br = new BinaryReader(fs))
{
buffer = br.ReadBytes(length);
}
context.Response.Clear();
context.Response.Buffer = true;
context.Response.ContentType = "application/pdf";
context.Response.BinaryWrite(buffer);
context.Response.End();
}
}
else
{
context.Response.Redirect(
"~/Error/invalid_access.aspx");
}}
in web.config I have the following for form authentication:
<authentication mode="Forms">
<forms name="Sample.Web" loginUrl="~/Security/" defaultUrl="~/default.aspx" protection="All" timeout="60" path="/" requireSSL="false" slidingExpiration="true" enableCrossAppRedirects="false" cookieless="UseDeviceProfile" domain="">
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>

I create two pages, the first one is the login page with user name and password textboxes - (not asp login control) , when clicking login button I check the login authentication, if it is true redirect to default page. in the default page if !IsCallBack then i check httpcontext.current.user.identity.isauthenticated
if it is false i redirect the user to the login page. but my problem is that the httpcontext.current.user.identity.isauthenticated is always false.
Below the section of authentication in web config

We have an SharePoint site no login (anonymous) with a search module using AJAX. Now the users complains that the module isn't working. When I check the code (not developed by me), I find that the code only runs if "HttpContext.Current.User.Identity.IsAuthenticated=true". Could that ever return true on an anonymous site?

I have a page where, when the user has successfully logged in, I store some values in the session.
I then use these values to load an application list page. This page is automatically refreshed after 20.1 minutes, with the sessionstate timeout and forms timeout in web.config set to 20 minutes (with sliding expiration). This means, if the user does not use any page for more than 20 minutes, he is timed out.
My problem is that the User.Identity.IsAuthenticated sometimes returns true, when the session has expired.
Why is this happening, and how can I fix it?

I need an app pool recycle to be completely transparent to the users of my web app. I use ASP.NET 3.5 MVC 1.
Currently, upon an IIS 7 App Pool recycle all users logged into my web app are kicked out and are required to log back in (Context.User.Identity.IsAuthenticated is set to false). I employ SQL State Server, I use forms authentication and both are configured to use cookies. I was under the impression that .NET and/or IIS handles authentication of cookies.
However, every time the app pool is recycled Context.User.Identity.IsAuthenticated is set to false my users are kicked out and are required to log back in. I can see that the session id remains the same throughout logins, I can also view this session information in the database/state server.

I want to share a common page load and page init events sequence between Master page and child page and User Control as described below:
Let us have the following components:-
1. TestMaster.master -> It is the master page
2. TestChild.aspx -> It is the Child page
3. TestUserContrl.ascx -> It is the UserControl present within the TestMaster.master page.

When I use a Master Page with a Content Page, in the Content Page script I find that User object is defined, with Identity and IsInRole properties. However, when I enter script on the Master Page itself User comes up as "not declared".
I am guessing that User is embedded in some namespace that is automatically imported to Content pages, but haven't been able to track it down.

I have implemented Forms authentication in an ASP.NET MVC 2 website
By using <%: Page.User.Identity.Name %> on the Site.Master page I can display the userid of the logged in user.
I would like to use this value and display other information about the user that is stored in a User table in a MsSQL database, like:
<%: GetFirstname(Page.User.Identity.Name) %>

I have a page that uses a user control, I have to detect the pages !IsPostBack in the User Control and do some operation
In the User controls page Load method I tried using the following variations to detect the first load
!Page.IsPostBack
!Page.IsCallback
!this.IsPostBack
!this.IsCallback
!this.Parent.Page.IsPostBack
!this.Parent.Page.IsCallback
None of these worked, they all fail to detect the parent pages 1st load in the usercontrols page load method
I also tried using
if (Request.UrlReferrer.AbsolutePath.ToString() != "/PreviosPage.aspx")
This worked for Fire Fox and Chrome but not IE (IE has issues with Request.UrlReferrer, it throws a null exception)
So I cant use this approach as well.

Is there a simple way to just retrieve the user's name, and not the Domain name, when using this function:
string quizTaker = Page.User.Identity.Name.ToString();
Right now it returns "DOMAIN_NAMEUserName"
I would like to just use isolate and use the user's name, without the Domain name.

I have a FormView and the SELECT statement I have is as follows:
SelectCommand="SELECT [UserName], [Full_Name_1], [Full_Name_2], [Email], [Address], [City], [State], [Zip_Code], [Home_Phone], [Cell_Phone] FROM [Homeowners] WHERE ([UserName]='<%$ User.Identity.Name %>')"... but it results in the FormView disappearing from the web page. Note: at the top of the page,
<%= user.identity.name %> displays the name fine, so user.identity.name does contain the info I'm looking for.I am trying to figure out how to correctly format the SELECT filter to feed user.identity.name to the SELECT statement as a filter. ... or if there is an alternative way.

I have a pre-existing app that allows me to display detailed record results from a database,and I've made a custom mod to it to limit the type of results(i.e. show me just THESE three tables instead of all tables associated with a record).I would like to make a hyperlink from the abridged version of the record to the full version of the record,but I can't for the life of me figure out how to do this!I know that the code in the .aspx file should look something akin to:
<asp:HyperLink ID="hyp1" runat="server" NavigateURL="http://server/file.aspx?d=" text="Full Report" target="_blank" />
I need to be able to insert a record ID in order to get the end-user to the appropriate results page,so I need to find a way to insert a field Record_ID at the end of that keyword string call (d=).
Any ideas of what I'm doing wrong and/or what I need to do to the code behind file?
I'm sure that this is one of those "can be done in 5 minutes" types of things once I know what I'm doing.

When any of my page is idle for about 20 minute, and after that if I hit any button, like Sumit Button or any other button, at this time, Page.IsPostback is again False, and none of the click event is fired and page gets reloaded again.
This happens only if I go like this, open up any of my webpage, keep it idle OR do nothing for about 20 minute, exactly on 21st or 22nd minute, Click on any of the button on the page, and the page gets reloaded, click event does not get fired. I debugged for this and I checked the Page.IsPostback value at this point and I got it as False after 20 minute, I don't know why. It should be True. And because of this my page gets reloaded and nothing gets submitted and every control is in the blank position once again and user have to enter everything again.
But if I enter everything and hit any of the button or Submit button within 20 minute, then everything works fine, Submit button's click event is also gets fired and everything works perfect.
And this is happening in all of my page. I am not sure what configuration is wrong.
But just for more details, I have a master page, I am using Telerik Controls and I have session Timeout set as 60 minute everywhere, in web.config and in IIS settings and in my App_Pool also. On my Master Page, I have ASP:ScriptManager, Tekerik:RadMenu, ASP:ContentPlaceHolder controls and some other controls and javascript code too.

Web pages are, by nature, state-less objects. When you click from page to page in an ASP.net application, each request for a page is treated as a brand-new request. We use things like cookies, session-variables, and query strings to maintain state from page to page.
When you log in to an ASP.net web application using Windows Authentication, how does IIS persist your identity between pages?

I'm trying to access User.Identity from my master page so I can figure out which user is logged in, however I can't get it to work. If I import System.Security.Principal in my master page it makes no difference:
<%@ Import Namespace="System.Security.Principal" %>
I can access it fine if I try within a Controller.

I have a database table and the column that has identity specification set to true is not displaying in numerical order. Whether I use Server Explorer and use Show Table Data or I create an application to view the contents of the table using a DataGridView I see that column displayed with the numbers often though not always in a non-numerical order.
Does it perhaps have to do with the way the rows for that column were added or would it be something else. I was looking at the properties for that column but don't see what I would change to make the rows display in numeric order.

In IIS 7.5 server I have a website apps.mydomain.com. Site binding for this website is:
IP: All Unassigned
Port: 80
Host name: apps.mydomain.com
In DNS there is an ip address pointing to apps.mydomain.com. Site comes up fine when browsing to this hostname.
I want to get current windows logged in username from asp.net web apps. I enabled windows authentication and disabled anonymous. Using this ASP.Net code to test:
Response.Write(Page.User.Identity.Name);
However, browsing to http://apps.mydomain.com/site/ the application pool identity shows as the Page.User.Identity.Name value and not the current windows logged in username.
If I browse to http://servername/site/ then Page.User.Identity.Name will return current windows logged in username.
Is there something else I need to configure to get the current windows logged in username when using host header?
web.config:
<?xml version="1.0"?>
<configuration>
<system.web>
<authentication mode="Windows"/>
</system.web>
</configuration>
App pool config (left out "handlers" for brevity, there's a 30000 char limit):

What are the differences (behind the scenes) between Page.User.Identity and Request.LogonUserIdentity? Not the differences in type, name, etc but the differences in how they're implemented behind the scenes (i.e. one calls windows xxx api and the other calls asp.net xxx api...).
