VS 2010 - Redirect User When Error Detected On A Page And To Notify Admin
Nov 13, 2011
I have this code , to redirect user when an error is detect on a page, and to notify the admin
vb Code:
Protected Sub Page_Error(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Error
REPORT IF ERROR DETECTED Dim a As New errorhandler
a.reporterror(Page.Title.ToString & " "
& Request.Url.Host.ToString, Server.GetLastError.ToString)
End Sub
then under another button I have this try and catch , i wud like to show the user there is an error on the date input format.
But whenever an error is detect the user is redirected to another page (errorhandler).I was wondering if it's possible not to redirect the user if the error is of type InvalidCastException .
I have got ssl security for my website.I have written onLoad that [URL] ... Should redirect on [URL] ... it redirects but first the [URL] ....pages loads full and then after a sec it redirects...I want to solve this
I am not able to redirect the user to "SimpleUserLoginAfterRegistration.aspx" page if Administrator is in any one of the .aspx file inside Administrator Folder.
I tried to use: Response.redirect("/SimpleUserLoginAfterRegistration.aspx") But, it is saying Page not found error.
I am creating a web application using Form Authentication of Asp.Net with C# and back end Sql Server. Here in my application administrator login and creates new users. I am using the create user wizard under login controls. My problem is when the new user is created by Admin he is automatically logged out and logged in with new user credentials which he has just created.
I wanted to know how to add the feature- that user should be redirected to an error page where the error will be display, upon entery wrong username/password when trying to login through an asp.net login control?
1. how to redirect the user to an error page upon entering wrong username/password (from a login control which is placed on master page)?
2. how to pass the error to the error page so it can be displayed there?
I would like to know what is the best way to do a notification in asp.net.For example I have a form in which the user will provide some data. He then click the save button which call the save methode in my code behind.
In the save method I need to query the database to know if another related object exist. If not I need to notify the user that he will have to create the related object. This does not prevent the user from saving the parent object.
So I would like to do a modal popup telling the user : Hey after Im done saving your change, you will have to open another form and create the child object.So should I create another NotificationWebform where the user will be redirect after the sava to notify him. It seems to be a "lot" of effort for a little notification. The best thing for me would be something like an alert in javascript.
When Iuse FTB in a normal web form I am having no issues. However when I create a master page then a web form that uses that master page I get the following error when pulling text from the FTB control
A potentially dangerous Request.Form value was detected from the client (ctl00_ContentPlaceHolder1_FreeTextBox1="<b>My TEXT</b>")
I get this error only when it uses html tags and only when its in a form that uses a master page.
What is the best way to show a message to user after session is expired? By then, the user should be logged out and redirected to start page. I can use javascript to redirect user to start page. I just want to show a message on start page.
I'm wondering if anyone else has encountered this. Ok, I have a website in which the solution and webfiles are in Team Foundation Server's source control. My workspace is on my local PC. If I go to Website > ASP.NET Configuration to manage the site using the web admin tool I get an error message from the web admin tool:
"An error was encountered. Please return to the previous page and try again."
Now, if I copy the exact site (just the website, but not the solution .sln file)to another location on my PC then choose open website in VS and fire up the web admin tool, it starts no problem.
I have no idea why this is happening and unfortunately the web admin tool doesn't give any other info other than that error message. Has anyone ever experienced anything like this?
I want to enable newly registered users on a site. I have figured out to put "DisableCreatedUser="True"" on the CreateUserWizard. What I have no idea about is how to have an email sent to the administrators email to notify them that a new user has registered.
I am trying to use the Application_Error to redirect the user to a custom error page. I know I could use the web.config to do this, but let's assume for now that this is not a desirable path to take.
Initially, I tried to do a Response.Redirect to perform this, however, there seem to be occasions where the current http context does not define the response object. So, I attempted to perform a check to make sure that the response object is not null prior to attempting the redirection, and if it is not defined, perform a Server.Transfer instead.
What happens is that in most cases, the Redirect causes the browser to some generic "friendlyish" error page rather than the requested error page.
So then I tried using Server.Transfer exclusively, and this worked well for most cases, however, sometimes the transfer didn't seem to take in the browser. Changing it back to a redirect in these cases solved that problem, but reintroduced the issue where the errors previously being captured and transferred now were being redirected.
What I surmised from this is that in certain contexts where the Application_Error method is trapped, it is necessary to use Server.Transfer in redirection, whereas in others, it is necessary to use Response.Redirect. The question then became twofold: (a) When is one necessary and when is the other? and (b) What available information can I poll to tell me when a given condition exists.
After much searching, I cannot find a reasonable answer to this question. So I began to trap errors and examine the HttpContext object for some indicator. One thing that I was looking for is the reason why if even with a defined Response in the current context does a redirect fail. The only thing that stood out is that even though a Response object may exist, the Session data could be absent. I added the case to check whether the Session data was null and perform a Transfer in this case and it seems to be handling it properly.
I emphasize "seems to be handling it properly" because no documentation I've been able to find confirms either the problem I am having or whether this is an appropriate strategy for solving it.
I guess the question is, am I on the right track here or is the null Session object just a red herring, indicative of nothing relevant. Here's the check I have set up for reference.

I found a great answer on SO describing how to set up custom user roles, and I've done the same in my project. So in my Login service I have:
public ActionResult Login() { // password authentication stuff omitted here var roles = GetRoles(user.Type); // returns a string e.g. "admin,user" var authTicket = new FormsAuthenticationTicket( 1, userName, DateTime.Now, DateTime.Now.AddMinutes(20), // expiry false, roles, "/"); var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(authTicket)); Response.Cookies.Add(cookie); return new XmlResult(xmlDoc); // don't worry so much about this - returns XML as ActionResult } And in Global.asax.cs, I have (copied verbatim from the other answer): protected void Application_AuthenticateRequest(Object sender, EventArgs e) { var authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { var authTicket = FormsAuthentication.Decrypt(authCookie.Value); var roles = authTicket.UserData.Split(new Char[] { ',' }); var userPrincipal = new GenericPrincipal(new GenericIdentity(authTicket.Name), roles); Context.User = userPrincipal; } } Then, in my ServicesController class, I have: [Authorize(Roles = "admin")] //[Authorize] public ActionResult DoAdminStuff() { ... }
I login as a user with the "admin" role, and that works. Then I call /services/doadminstuff - and I get access denied, even though when I put a breakpoint in Global.asax.cs, I can see that my roles do include "admin". If I comment out the first Authorize attribute (with roles) and just use a plain vanilla Authorize, then I can access the service.
and also i set the ValidateRequest="false" in the page directive's. and in code behind i also use HttpUtility.HtmlEncode . but again and again i am facing this error
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtEmbed="<embed src='http://a...").".
