Web Forms :: Server.Transfer Throwing "StackOverflowException" When Being Used In Master Page

Feb 17, 2010

I have a very simple application. You have a master page. Within the CS of the master page you do a Server.Transfer to another page that inherites the master page. As a result you get an infinite loop. The problem is that I can't check with if statements to prevent the loop.

Web Forms :: How To Hide A Page Url Without Using Server.transfer

Dec 23, 2010

Sometimes when transferring to a different page, I have to use response.redirect instead of server.transfer, and when I do, the name of the page always shows up in the url such as [URL]

I use server.transfer when I can, but unfortunately I haven't found a way to use it unless the transferred page refers back to the parent when leaving.

How can I mask what page is being viewed after doing a response.redirect to another page.

C# - Is It Safe To Use Server.Transfer() To Transfer A Request To A Static Image (.jpg - .png)?

Feb 8, 2011

I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");

This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.

Web Forms :: Define Reusable Master Page Type To Reuse Parts Of The Master Page?

Jan 5, 2011

My Project is a normal web site, not a Web Project, and I am using VS 2005.

I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.

I added the following in app_code:


Also, I added the following in Master Page Source Declaration:


Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.

Why I am doing this ?

This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).

Web Forms :: How To Transfer Customer Http Header From One Page To Another Page

Sep 22, 2010

I need to pass api key in custom http header ('X-ApiKey') and pass to another page. The second page will read that api key and do further processing. If api key is not passed in, it will redirect to error page.

I tried this way, but it didn't work.

In First.aspx page

Response.AppedHeader("X-ApiKey", "xxxxxxxxxx");

In Second.aspx page

string apikey = Request.Headers.Get("X-apiKey");

but X-apiKey is not passed in in second.aspx http header and ended up redirecting to error page.

Web Forms :: Master Page Event Not Firing On Remote Web Server

May 18, 2010

I have a master page with a login box on it. Inside the login box is a button -


NOW ... On my local dev machine this code works fine. The control fires the event and everything is how it should be. When I run this site on a remote web server (tried two of them - both IIS7 running on 2008 R2) the event is never called. I added some logging to see what is happening and the PostBack event on the Master Page does not happen when the button is clicked - the page is just reloaded.

C# - Page Methods Throwing Undefined?

Dec 1, 2010

I am trying to use page methods to call a function and I am getting a "PageMethods is undefinded" error. I have used them before whilst using C# but not VB so I'm wondering if my syntax is wrong as all examples I can find are C#.I am also wondering if it's because my scriptmanager is on the master page?I've read about this error everywhere but everything I have appears to be correct!

My code:

Part of Master Page

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" EnablePageMethods="true" >

Web Forms :: Master Pages - How To Access Content Page From Master Page

Sep 5, 2010

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?
