Web Forms :: Redirect In Custom Event Where Response Or Server Is Not Available?
Feb 24, 2011
I am using a custom event in third party library for my asp.net project. When the event happens, I need to redirect to another page. Problem is that since it is custom event, Server.Transfer or Response.Redirect can't be used (I tried but got "response is not available in this context"). So I think best way would be to trigger post back in the event and redirect in page_load event on appropriate conditions. Is this right approach or is there any better idea? And, how can I trigger postback?
Try client.Send(msg) Global_asax.myLogger.Log(BitFactory.Logging.LogSeverity.Status, (-- Status --> form sent email to " + msg.To.ToString)) btnSendmail.Enabled =" "False" Response.Redirect("http://www.google.com/")
i am submiting a form on the button click and redirectiing to a site. But it is not working.
rl711 You have to use target attribute in form tag: <form runat=server target=_blank> // new window or <form runat=server target=_top> // above all frames or <form runat=server target=_parent> //parent frame or <form runat=server target=someframe> // a frame by name
This can only work if the Server.Transfer is invoked from within the form such as a button click.
If your Server.Transfer method is in the Page_load event (which isn't a form event), how do you set a target window to Server.Transfer?
I have to choose between Server.transfer and Response.redirect for an Intranet application for navigation. I have chosen Server.Transfer as of now because it avoid extra round trip to server and which will help when so many users will be accessing the application. (I believe this is the main difference between reponse.redirect and server.transfer). But the problem is now that URL won't change on Server.Transfer(I don't want to implement Http headerS, as I am afraid it will take time to implement that).on redirection, I want to do something like taking benefit of server.redirect(in avoiding server processing, which happens in response.redirect) and changing the URL(as it happens in reponse.redirect).Can anyone please suggest a quick solution to it or may be help me Telling How many users can reponse.redirect can support ?
This is the very favourate question available on every interview questions site. I have searched for it. But didnt get the satisfactory practical difference between these two. show me the difference between this two through a working sample demo.
we are running into an issue with our ASP server. If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie. Members/MemberLogin.aspx?doc=/PodCast/Default.aspx) The vb script places the "/PodCast/Default.aspx" in a variable and holds it until the login process is complete. Once the user types in their username and password it is suppose to do a Response.Redirect(strRedirectURL) and go to the "/PodCast/Default.aspx" but instead it goes to the default.aspx page for logging in successfully.
The kicker is, I know the code is 100% correct becuase it was working on our previous server, but when we pushed all the data onto this server, everything works BUT that piece.
I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?
Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.
I have a base server control class for all my user controls. Inside this class I have the following declaration:
Concrete user controls used in the application are used always inside a ModalPopupExtender object and the popup it is always handled with server-side code. This means that there are no controls binded to the OkControlID and CancelControlID properties of the ModalPopupExtender.
The responsibility to show the Modal Popup is then given to the aspx that has code like this in the ASPX file...
To hide the modal Popup the aspx just implement the event handler
Last, the event firing is responsibility of the concrete UserControl class that can use any way to do it's work and then fire teh event. This is done through this code:
The problem I am facing to is that in the OnItemSaved of the super class the ItemSaved EventHandler is always null and so the event it's never fired on the aspx page. Where am I doing wrong?
I come from the Windows forms side and started using ASP.NET. I have not found how to use event handlers properly.Basically I want to create a shopping cart web control. When a purchase has been made I want to raise an event with products in the purchase. I would like to have the shared/static event and delegate on the web control and then, maybe in Global.asax (if not possible elsewhere) handle that event.
How can I do this? It seems I cannot access objects from other pages/controls.
I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).
How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
