C# - Masterpage Response.Redirect Before Child Call?
Aug 23, 2010
I have a masterpage and inside that masterpage I have to check if a session is null or not. If the session is null, then there has to be a redirect to a login page.
That is no problem, but the problem is that the masterpage also have controls using the session and the child also uses the session so I get a nullreferenceexception.
I now have this:
[code]....
But the problem is that the controls on the masterpage are also called instead of redirecting immediatly.
So the main question:
How can I redirect immediatly, without loading further things. Because the page_init gets called as first method the redirect should solve my nullreferenceexception, but than I don't need to load all components etc.

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.

I got a ASP.Net website (webforms application in C# - .Net framework 2.0) with Master Page, webforms and a GlobalFunctions class in App_Data folder where i do have ErrorLog functions and few other generic functions. Everytime an exception is caught in my webform it calls this GlobalFunctions.Errorlog function to log the error in my database table. After the exception details are written to the database table, I also would like to redirect the user to my ErrorPage.aspx like
Response.Redirect("ErrorPage.aspx",false);
However since i am inside a class (GlobalFunctions.vb) and not a webform, I don't know how to redirect this to ErrorPage.aspx since i can't access Response class.

I have a page that when the user clicks a button there is a custom loading panel placed in the update panel by the PageRequestManager BeginRequest event. So when the page is loaded the loading panel is removed. My issue is that when the user clicks a button that redirects to an httphandler the page is not reloaded therefore the loading panel is never removed.
So I'm trying to think of a way to remove the loading panel before the redirect occurs, whether this be with a client script call before the redirect or what ever. So far I've thought about trying to do Response.write("..."), then Response.Redirect().

I have a try-catch inside a method that is called asynchronously. When an error occurs, inside the catch I have a Response.Redirect because I need to redirect to the login page.
This is my issue.
But my problem doesn't involve things that expire, so the idea of a timer isn't the best way to resolve it.

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?

what's the DIV equivalent to this command?
((Panel)this.Page.Master.FindControl("Panel1")).Style.Add("display", "none");
This works great with a panel but I can't find the variation for doing the same thing with a DIV who's ID I know.

I have a some javascript code that I only want to run in one child page but it needs to be in the head tag to function correctly.
<script type='text/javascript' src=[URL] ></script>
<script type='text/javascript' src=[URL]></script>
<script type='text/javascript' src='lightview/lightview.js'></script>
<link rel="stylesheet" type="text/css" href="lightview/lightview.css" />
end code
Can anyone tell me how to do this? I cannot put it straight into the master page as it conflict with some other javascript code that I am running on a different page! And I cannot put it into the body of the child page because it does not function correctly.

I have a main MasterPage that, as intended, forms the entire layout of my site. It has a bunch of methods common to all pages that use the mastertype, such as EnsureLoggedIn and such.
I want to move on to using nested masterpages to open up better layout options in some of the pages, but I am running into an issue. I get the layout of the nested masterpages fine, but I cannot access any methods in the parent masterpage.
I know my explanation seems a little sparse; I'm not exactly sure how to word what I'm looking for, heh. But here's a short example:

I have a ASP.NET C# 3.5 web application, where I am changing the masterpage & theme for certain pages that have ASP.NET controls. The problem is that when the masterpage/theme is changed, the ASP.NET ImageButtons on the child page cease to function altogether and show up as normal images. The html source for that page would show a disabled="disabled" field added to the ImageButtons at runtime. All other controls including ASP.NET Buttons work fine, only ImageButtons are effected. I've changed masterpages in files many times and have not come across this problem, probably because I rarely use ImageButtons. I'm beginning to think it may be a bug in .NET itself, but it could be code related. I've also executed a javascript function after
load to set the disabled field to "enabled", which has no effect on the ImageButton but the source confirms it is enabled. The MasterPages / Child Pages are relatively straight forward and I've tried many different combinations to get it working. I'm changing the masterpage & theme via a function like:
public static void ChangeMaster(System.Web.UI.Page page)
{
page.MasterPageFile = "~/GX.Master";
page.Theme = null;
}

I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.
I have an example here of what I am trying to accomplish:
[URL]
I am using asp.net with VB.

I'm embarrassed to ask this here because it's clearly been duplicated several times already on StackOverflow. I've read a lot of stuff including:
[URL]
I think I've done exactly what those article say, but it's not working for me.
Here's the top of my master page, named "MasterNoNews.master":
[code]....
In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.

Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.

I have a masterpage and 1 childpage. In master page there is a listbox to present a data when a child page button is clicked. Listbox name is x1 for example.
When i am in childpage's button click event: i do not see that x1 named listbox due to namespace i guess.
For example masterpage name is masterpage1. When we are in childpage in button click event.
To try masterpage1 objecttemp = new masterpage1()
button1_Click() (child pages button click event)
masterpage.x1.items.add("button 1 clicked"); it is not being able to reachable too.
Also i encountered another issue related to that. When in masterpage for example masterpages click event. (its a login panel and when user clicks login, i had wanted to add a text information to listbox). In child pages when user clicks to login button which belongs masterpage top panel. It does not seem like working. It may be related to asp page master child life cycle and i do not know good. I wanted to able to add a string to listbox that belongs and come from masterpage in child page. Is there any way to use a datacontrol in childpage that belongs to masterpage.

have a website with MasterPages, on load master page has many database roundtrips and logics implemented.Now, if move to one page to another, the MasterPage get reloaded and all the above mentioned procedures processed again, which again takes a lot of time and as a result my website's response is very slow.For eaxmple, once the default page is loaded, all the child pages can load within the centent area (in ajax style).
tell me some workaround to optimize the site so that it doesn't this procedures repetitively.

I am working on a website that I inherited (ASP.NET and C#), and I noticed that in almost EVERY method in the code behind of the project pages (except some helper methods), the original author uses Response.Redirect() to redirect to a page (typically home.aspx, but not always).
What is the purpose of doing this? It seems unneeded to me - at least it doesn't appear to change anything the website is doing if I keep it in or remove it.

I have a flash image slider with a button below each image. When i press that button, the user is redirected to a new page where i add that image product to my cart. The problem is that after doing the adding, i want to redirect the user back to the initial page.
The code:
protected void Page_Load(object sender, EventArgs e)
{
addProductToBasket(getCategoryIdFromUrl(), getProductIdFromUrl());
Response.Redirect(Request.UrlReferrer.ToString());
}
note that in Firefox is working fine but in IE or Chrome it is DOWNLOADING the swf...If i comment Response.Redict(...) the user remains on this page so the click button is working well, only the redirect seems to be the problem.
Edit: The problem seems to be that Request.UrlReferrer keeps as link not the initial page containing the swf but the swf itself.
So, instead of doing redirect to:[URL] if does redirect to the swf contained on the Index.aspx page[URL]
Solved: with a session variable where i keep the initial page's url
