Getting SharePoint absolute site url - asp.net

I need to get the current absolute url of my site from inside an aspx page (no codebehind).
I tried $SPUrl, but it get's converted into a relative url.
<asp:Literal runat="server" text="<% $SPUrl:~Site/mypage.aspx %>" />
results in "/mypage.aspx". It's important that I get the full absolute url starting with "http://".
<asp:Literal runat="server" text="<% $SPUrl:~SiteCollection/mypage.aspx %>" />
does the same. The goal is to get this url: "http://myspweb.com/mypage.aspx" as result.

Jason is correct on how to get the URL.
One thing to realize however about SharePoint is there may not be an actual "true" absolute site URL. With a SharePoint content database, you can extend the application to different IIS applications which have different web.configs, etc. Often people do this when they have an extranet for employees (Active Directory security) but will then want to allow customers in via Forms Based Authentication. That is one of the main reasons that SharePoint converts things to a relative URL.

You could use SPContext.Current.Site.Url to get the absolute url of the current site collection:
<%# Import Namespace="Microsoft.SharePoint"%>
<!-- ... -->
<%= SPContext.Current.Site.Url %>

ASP.NET redirect pagename.aspx/something to pagename.aspx

Ok, I didn't know how to phrase this differently. Basically, I have an issue on my website, where writing pagename.aspx/anything will open the page pagename.aspx but with no styles or images cause they have relative paths. It's not possible to rewrite them to have absolute paths. Is there any way I could make it work somehow (like for example, redirecting it)? Thanks in advance.
For converting any application root relative URL (which is the most common format) to the appropriate URL on the client in a Web Forms page, you can use this code:
<%# ResolveClientUrl("~/path/to/file.css") %>
Example:
<script src='<%# ResolveClientUrl("~/Scripts/jquery-2.1.0.min.js") %>' type="text/javascript"></script>
However, in cases where you're using server side controls (for example, asp:Image instead of plain img element) then you can use the application root relatively URL without needing to resolve it.
<asp:Image runat="server" ImageUrl="~/images/myimage.jpg" />
is equivalent to
<img src='<%# ResolveClientUrl("~/images/myimage.jpg") %>' />

Same piece of code works on one page & doesnt work on other Page, asp.net

nesting of image inside a LinkButton shows image on one page & doesn't show image on another page below are two sample code from two different pages in the same root director.It works fine on one page but on the other page is doesn't show any download image rather shows the text download in place of image.
I have done troubleshooting for sometime and replace the code also but it doesnt show download image for any reason on the second page..
<asp:LinkButton ID="lnkbtnDownload" runat="server" onclick="lnkbtnDownload_Click" meta:resourcekey="lnkbtnDownloadResource1">
<asp:Image ID="imgDownload" runat="server" ImageUrl="~/images/download.png" meta:resourcekey="imgDownloadResource1" />
</asp:LinkButton>
<asp:LinkButton ID="lnkbtnDownload" runat="server" onclick="lnkbtnDownload_Click" meta:resourcekey="lnkbtnDownloadResource1">
<asp:Image ID="imgDownload" runat="server" ImageUrl="~/images/download.png" meta:resourcekey="imgDownloadResource1" />
</asp:LinkButton>
HTML OUTPUT
HTML for above two code sample render as below
<img alt="Download" src="images/download.png" id="MainContent_imgDownload">
Download
Both Pages are in the same root directory...
The problem probably comes from a discrepancy in your resource files or missing a resource file completely for the second page. Obviously you have one for the first, but possibly not for the other which has different naming.
If you are using meta:resourcekey, there are some things you have to considerate.
Make sure that your local resource files meet the following criteria:
They are in an App_LocalResources folder.
The base name matches the page name.
For example, if you are working with the page named Default.aspx, the
resource files are named Default.aspx.resx (for the default
resources), Default.aspx.es.resx, Default.aspx.es-mx.resx, and so on.
The resources in the file use the naming convention
resourcekey."property". For example, key name Button1."Text".

Can I set the language of a web page using ASP.NET resources but no code behind?

I have a kendo single page application that I need to localize. I tried using Javascript to translate text parts, but it gets complicated when translating non HTML bits like templates (inside script tags) and properties like "data-title".
Next I tried changing the extension to .aspx and using ASP.NET resources, as in this example:
<!-- logout -->
<div id="logout" data-role="view" data-layout="layout-logout"
data-title="<asp:Literal ID="Literal1" runat="server" Text="<%$ Resources:TextStrings, Logout%>" />"
data-before-show="myproject.logout">
<div style="padding: 50px 0; text-align: center;">
<p id="lang_LoggedOut"><asp:Literal ID="Literal2" runat="server" Text="<%$ Resources:TextStrings, Logout_Success%>" /></p>
</div>
</div>
This works to some extent, as the <% resources %> bits get replaced.
However I had to transfer login to a separate .aspx page to apply the language, after login (and discovering user culture), but before single page app load.
The login page calls the customary:
protected override void InitializeCulture()
to set the culture, and then redirects to the main app page.
As far as I can make out, the InitializeCulture is ignored, but the page is rendered with the strings from the resource files, sometimes in one language, sometimes in another.
How does ASP.NET decide what culture to apply, and how can I control that choice?
Notes:
failing this, the kendo people seem to suggest having one page for each language, which rather goes against my DNRY inclinations.
Code behind and inline code (<%Page%> directive) are in my experience incompatible with kendo. If I understand right page events get stolen by one another. Kendo is compatible with MVC, but I must learn MVC first, and then get resource files to work with MVC.
The short answer is yes. I have seen it work with VS2010 and IIS 7.5.
The page with no code behind must have an .aspx extension.
the language selection must happen on another .aspx page with code-behind. Call InitializeCulture() here
from this page you must go to the main page using Server.Transfer. See: Server.Transfer Vs. Response.Redirect
Server.Transfer will keep the settings and context you set, and apply the language to the page with no code-behind while the user navigates the page.

ASP.NET relative path

I'm confused with ASP.NET relative path, please can someone help?
In a Master Page I gave a link label referencing:
Login
From the ASP.NET official documentation I read:
The following example shows the ~ operator used to specify a root-relative path for an image when using the Image server control In this example, the image file is read from the Images folder that is located directly under the root of the Web application, regardless of where in the Web site the page is located.
<asp:image runat="server" id="Image1"
ImageUrl="~/Images/SampleImage.jpg" />
With the Login markup, when I click the link from a page in the /Account folder, I'm redirected to:
/Account/~/Account/Login.aspx
Why? WHY?h
Because you're using it directly in markup, rather than in a server control. Something as simple as this should fix it:
<a runat="server" href="~/Account/Login.aspx">Login</a>
Basically, the ~ path reference needs to be translated on the server, since it's a reference to the server path of the application's base directory. Plain HTML markup isn't processed on the server, it's just delivered as-is to the client. Only server-processed code will translate the ~ path to what it resolves to.
use this command
<a href="<%=Page.ResolveUrl("~/product.aspx")%>" >Link To Products</a>
You can use ~ when refering to URLs inside ASP.NET Server Controls.
You are using it in a <a> tag which is just plain html that doeesn't know anything about ~ . use '"/Images/SampleImage.jpg"' instead

ASP.NET ~/ not resolving to "/"

My application paths …
<a runat="server" href="~/Home">
…are resolving to “Home” (not “/Home”). After I rewrite URLs, “/Blah/Blah”, all the ”~/” links are relative to the rewrite: /Blah/Home
Is there a way to force a root to “/”?
Why don't you just write the links relative to the root ('/') instead of '~/', if you're application is not at the root of the domain, then the '~/' links will resolve to the root of the application
If you're sure that, for the links in question you'll always be at a root of "/", then the simplest thing to do is change the <a> so that the href reads "/Home" rather than "~/Home" ... That way asp.net won't parse it and change it to use the App/VDir as its starting point.
If you use standard HTML tags like a, then include the url via
...
or use asp.net hyperlinks:
<asp:Hyperlink NavigateUrl="~/Home" runat="server" ID="HomeLink" Text="..." />
That way, all links will point to the right URL, even when the web application will be installed in a subdirectory.
<% %> is inline coding for asp.net, and <%= %> outputs the content, in that case the result of ResolveUrl.
~/ gets translated in the web controls, as in not Otherwise, you need to use ResolveClientUrl to do that.
For the hyperlink control, it will automatically map correctly for you.
