Modify Request Querystring Parameters To Build A New Link Without Resorting To String Manipulation
Apr 6, 2010
I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:
Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring
string str = "LDAP://company.com/OU=MyOU1 Control,DC=MyCompany,DC=com"; Regex regex = new Regex("OU=\w+"); var result = regex.Matches(str); var strList = new List<string>(); foreach (var item in result) { strList.Add(item.ToString().Remove(0,3)); } Console.WriteLine(string.Join("/",strList));
the result i am getting is "MyOU1" instead of getting "MyOU1 Control"
it contains can contains either of (1) strQuery = "TempTable.Group_No IN ()";
(2) strQuery = "TempTable.Group_No IN (1,2,3,4,....)";
My task is if it contains "TempTable.Group_No IN ()", (i.e) IN CLAUSE without data i have to replace the string (IN() with IN (NULL)) with "TempTable.Group_No IN (NULL)"
When I try to remove the last few characters of a string, I get an index out of range error. I am using the following to remove the characters from the end of the string: objJSONStringBuilder.Remove(objJSONStringBuilder.Length - 1, 6) The string has <hr /> at the end which I want to remove.
I need to dynamically modify the contents of a column in a GridView1 before it is displayed. Basically, I need to convert every 'Environment.NewLine' in a field to a so it displays as a new line on an ASP.NET page. How do I do this?
and at the page load event i retrieve the value of the label & assign it to a string !
stringvalue = lbl_Hidden.Text;
Now i dont know why this manipulation does'nt work! I've a character 'A' in the string and i'm unable to replace it with a space ! stringvalue.Replace(A, " ");
I can a split function and split on the backslash character to get the pieces. But if my directory could change this wouldn't work. So how would I instead parse out the last backslash and get the filename that way so that it wouldn't matter if the path changed?

Since ASP.NET MVC3 RC2 I encounter a bug when posting values to a controller method of which one of the parameter is a nullable int. Steps to reproduce:
I've created a test method
[code]....
In MVC3 RC1 this was working without any problems with the nullable int
Update: I don't seem to have the problem with a newly created MVC3 website. What could I have in my project that influence model binding to nullable int's? And why would there be a difference between RC1 and RC2?
I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5 To http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3 To http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs
I'm a bit new to this game. I'm trying to build a web page that simply scans a directory in the server and creates a web page with links to the files in that directory - sounds simple and should be easy to do !So I have a bit of code that reads the myDocuments folder in my web site and then populates a grid view hyperlink column with the filenames in the folder - wow it works !The only thing I am struggling with now is getting the hyperlink correct within the GridView so that the user goes to the actual document.So my code behind is;
[Code]....
which reads the file info in the directory myDocuments and binds the info to a datasource.So now I'm using that datasource to display the filenames in a gridview so that the user can click on a name and open the file.
[Code]....
But of course the Name field in the hyperlink column is only the name of the file - how do I append the relative link to the filename to make the full path to the file correct.I tried to make the Hyperlink column a template field and do something like EVAL("~/path/"&"Name") but that doesn't work :(
In Web Forms I would tend to do this by having one actual page. I would then use a tab container to give the appearance of several pages of a "wizard" by enabling and disabling tabs. Of course the URL wouldn't change, but otherwise it gave the impression I wanted. The values of the hidden controls were maintained in viewstate, and when the submit button on the last page was pressed I could obtain all the information I needed from the state of the controls.This obviously is not how it should be done with MVC. However, I don't really want session state or to write partially complete submissions to the database. What is the best way of handling this?
I try to have an URL like this /Forum/Index/2 for url I have a route {controller}/{action}/{page} in my global.asax
If i test the above url with the Route Debugger it corresponds to the above route ( and some other but this is the fist one in the list ) but if I create an url with the ActionLink
( like this : [Code]....
), this methode return me this URL /Forum/Index?page=2 Is there a way to a have an url with nothing in querystring with the ActionLink methode ? Gauthier
I wanted to ask about URL rewriting. I want to map this: [URL] To: [URL] Being DVD players product id 123.
Also I will like to map sub domains like this: From: [URL] To: [URL]
Being John Doe user id 123. I will like to do this by getting the respective ID (for products and users) from a database based on product id name (dvdplayers) and sub domain name (johndoe). Where can I intercept these 2 (sub domain string and product name string) and based on this getting the info from DB and "rewrite" the URL's?
How can I pass two querysting parameters in URL routing using ASP.NET 4.0? I have gone through many articles, but everywhere it shows only one parameter. I'd like the display URL to be: [URL] The first parameter is ID: 1 The second is Name: This is my first report I am trying following route, but it is not working
routes.MapPageRoute( "MarketReports", // Route name "Reports/{*i}-{*n}", // Route URL "~/pageControl2.aspx" // Web page to handle route );
I am using a third party service that does an async callback to a URL I provide to them. So I tell them to use [URL] This must obviously map to an Incoming() method on my StatusController.
However, what I don't have control over is the format of the parameters they call my URL with. E.g. They will do a callback such as: [URL] I want to map this to the parameters of my action method: Incoming(string param1, string param2, int param3)
