How to get the previous url in a MasterPage in C# ?
I'm trying to find the page which is redirected from.
Thanks in advance.
You can get information of the previous url with the UrlReferrer property. This works in MVC and Web forms.
Request.UrlReferrer.AbsoluteUri
Note that in the first page the property Request.UrlReferrer will be null. Also, it will be null if a redirection occurs (e.g. when a user logs into the web page).
This property is based on the HTTP_REFERER variable, so you could use this one instead.
Request.ServerVariables["HTTP_REFERER"]
Since the HTTP_REFERER is a variable sent by the client it might be altered or removed by the request. Also, the variable is not set when the referre url starts with https.
This article mentions a few points why the Request.UrlReferrer can be null.
Usually you use a query string parameter to achieve this: current?previousUrl=/some/11.
This will allow you to access this value from the server-side code using Context.Request.QueryString["previousUrl"] in your master page code-behind.
string urlName = Request.UrlReferrer.ToString();

How to get current request url
I type in browser:
http://srv-1/sites/1001/Account Documents/Order
but in Page_Load in my controls I get
HttpContext.Current.Request.Url = http://srv-1/_layouts/15/start.aspx
and
Page.Request.RawUrl = Page.Request.RawUrl
I need to retrieve information: /Account Documents/Order
This happens because of Minimal Download Strategy feature. Your url is rewritten by SharePoint.
Easiest solution is to disable this feature, but you can also try to get url via SPUtility.OriginalServerRelativeRequestUrl property or refactor your code not use url, but current library or something else.
SharePoint does it’s own URL rewrites, if you would try that for example for the page
The solution is to use special property on [SPUtility class – SPUtility.OriginalServerRelativeRequestUrl][1]
http://blog.voyta.net/2012/07/09/how-to-get-original-request-url-in-sharepoint/
This property returns the original URL before it was rewritten, which is useful if you need to get the subweb from which an application page was loaded.
As this URL is server-relative, to get full url, you can use:
SPUtility.GetFullUrl(SPContext.Current.Site,
SPUtility.OriginalServerRelativeRequestUrl);
This can be useful if you need to redirect for example to the same URL with some additional parameters.
Thanks
I want to get the absolute url of .net application with bookmark.
So if the request is coming from - www.mysite.com/myapplication/Home/Index#about
then how to get the above url in .net application?
I tried HttpContext.Request.Url.AbsoluteUri but it is returning - www.mysite.com/myapplication/Home/Index but how to get bookmark ("#about") part of url?
It is not possible: anything after the # is not sent by the browser, it is only used inside the loaded page for navigating to anchors.
The browser doesn't transmit that part to server.you should use java Script like this answer
Try this,
assuming that the variable url holds your actual url
string[] bookmark = url.Split('#');
and the bookmark[1] will hold the Value of your bookmark, also.
string bookmark = url.Replace(HttpContext.Request.Url.AbsoluteUri(url), string.Empty);
I need to get the url of the site so that I render a user control on only the main page. I need to check for http://foo.com, http://www.foo.com, and foo.com. I am a bit stumped as to how check for all 3. I tried the following which does not work.
string domainName = Request.Url.Host.ToString();
if (domainName == "http://nomorecocktails.com" | Request.Url.Host.Contains("default.aspx"))
{ //code to push user control to page
Also tried
var url = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + "/";
Any thoughts?
You need to check if the Request.Path property is equal to / or /Default.aspx or whatever your "main page" is. The domain name is completely irrelevant. What if I accessed your site via http://192.56.17.205/, and similarly, what if your server switched IP addresses? Your domain check would fail.
If you utilize the QueryString to display different content, you'll also need to check Request.QueryString.
Documentation for Request.Path:
http://msdn.microsoft.com/en-us/library/system.web.httprequest.path.aspx
Documentation for Request.QueryString:
http://msdn.microsoft.com/en-us/library/system.web.httprequest.querystring.aspx
If you need the user control to only appear on the main page (I'm assuming you mean home page), then add the code to call the user control to the code behind of that file.
If this code is stored in the master page, then you can reference it like:
Master.FindControl("UserControlID");
If you are only using the one web form (ie. just Default.aspx), then you can check that no relevant query strings are included in the URL, and display only if this is the case:
if (Request.QueryString["q"] == null){
//user control code
}
However if you are using this technique then I would recommend using multiple web forms using master pages in the future to structure your application better.
The ASP.NET website has some good tutorials on how to do this:
http://www.asp.net/web-forms/tutorials/master-pages
I have a certain document type in Kentico that has a boolean field that when true i need the page to redirect to another URL (in this case a 404 page).
Where is the best place to do this?
and how do i access the kentico data context in code so that i can write code that pulls the document types field and redirects based on it (because currently trying to access Dataitem("MyFieldName") errors because Kentico doesn't use DataItem for data binding, even though Eval("MyFieldName") still works.
You can access Kentico context data via the CMSContext object.
<%
if ((bool)CMSContext.CurrentDocument.DataRow["MyFieldName"])
Response.Redirect("PageNotFound.aspx");
%>
If you only want to be able to redirect a page to another page. Kentico already have something built in, just go to the Page->Properties->Menu. In the menu actions section you can specify a URL for redirection.
Otherwise for requirement described you can get the boolean value by:
if(ValidationHelper.GetBoolean(
CMSContext.CurrentDocument.GetValue("MyFieldName"), false)))
{
Response.Redirect("/404.aspx");
}
I am very beginner With Programming...(unfortunately)
I want to remove Any added QueryString To Address after i get the variables. for example:
www.websiteName.com/page.aspx?a=344&b=233
i will get a and b and after that i want my address to look like this:
(www.websiteName.com) .
"root location".
any help...
thanks.
var queryString = Request.QueryString;
// Handle querystring, then redirect to root
Response.Redirect("~/");
Response.End();
You will have to reload the page. When changing the URL, you are making another request to the server.
I wrote a blog on retrieving the URL of an ASP.Net application. Simply add the page name after the result.
This blog describes how to manipulate the query string to redirect to the same page with different (or no) parameters.
Why not just use
Request.UserHostName
