C# - How To Route "pretty" Dynamic URL (without Query String)
Dec 20, 2010
Well, i know the title isn't very specific, but i couldn't find a better succint description of what i'm looking for.i want to have a default.aspx so that when a user types:
http://www.mydomain.com/randomstring
i can use the randomstring to query a table on page load. More specific:
. I will be importing batches of users to my database through a csv file.
. in that process, a random string will be generated
. i will send that url to each user by email
. when the user clicks through that link, i want my aspx(c#) to interpret that string, query a table that gives me a second url, this one with querystring, and Redirects the user to that second address

I'd like to change my routes so that instead of having:
/Users/Edit?UserID=1
I can do
/Users/Edit/1
How can I create a custom route to do that?
Also, can someone direct me to a good tutorial on routes? I don't wanna create a post every time I have a simple problem with routes.

The Html.ActionLink
<li> ${Html.ActionLink<HomeController>(c => c.Edit(ViewData.Model.Id, ViewData.Model.Title), "Edit")} </li>
When created as html shows the URL to be Edit/5006?title=One . How do I change this to a pretty URL like Edit/5006/One ?
My Edit Action method is,public ActionResult Edit(int id, string title)

ASP.NET 3.5, IIS7,In my Global.asax's Application_BeginRequest, I need to extract from the request's URL an entirely seperate URL that's been embedded in it without using query string.
The solution I came up with was to hex-encode the entire target URL as if it were a directory, as follows:
http://localhost/687474703A...etc...732E6D7033/irrelevantFilename.txt
This fails for IIS7, whose ASP.NET implementation won't tolerate a URL path greater than 260 characters.My code controls how the request URL gets generated, and how it might embed the target URL in there, but it doesn't have any control over that target URL value (they're third-party URLs).How better could I embed this target URL in my request URL?

I recently encountered a problem when our project is derived to client. We used a single web page called default.aspx and passed parameters as querystring to load different webpages [URL]? p=232&q=90&id=3). But the client need a meaningful url [URL]. If we create each page for the client data we get millions of web pages and it is hard to create. Now we need to display dynamic data without passing querystring and they should look like individual webpages insted of a single webpage.

I want to add a dynamic prefix to the url for some of the Views in my site, e.g. [URL] but am having difficulty. Out of the box I have [URL] but need to set a prefix dynamically. I created another Route in the Global.asax like so, but is is even needed? If it is how do I call it from my controller?
routes.MapRoute(
"Questions", // Route name
"{dyna}/{controller}/{action}/{id}", // URL with parameters
new {dyna = "dyna", controller = "Quote", action = "Questions", id = UrlParameter.Optional } // Parameter defaults
);

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

Example:

I added the iis tag because I am guessing it also depends on what server technology you use?

I have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."

How do i get the pretty URL with an ASPX pages. I have listed a couple links below and their associated print page url. As you can see it resembles the Class instantiation method of declaring object but is used for a webpage with its extension.
I was wondering if this method can be used or if this is a URL rewrite to mask all the querystrings and sub directories being referenced. I remember doing stuff like this when i was working on a UNIX system using the .htaccess file to mask effective query
string being shown. I believe they called it a Clean URL, i maybe wrong as it has been well over 8 years since i dealt with the Unix .htaccess file and massaging urls with it.
For instance, look at the MSDN site pages:
http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception.aspx
Now when you want to print it:
http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(printer).aspx
Now you select the same page but choose a different framework than its birth:
http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(VS.100).aspx
and the print URL:http://msdn.microsoft.com/en-us/library/system.servicemodel.actionnotsupportedexception(VS.100,printer).aspx
As you can see they are not visually passing query strings but more like Class parameters. Is this just a simple URL rewrite after the page is loaded so the user doesnt see the query string information?

I'm exporting a PDF report from Crystal Reports bundled with VS2008. I need to display non-standard fractions so that they look nice instead of just something like 26/32. I have turned html interpretation on for the field so ½ and other standard html entities display nicely, however, because CR does not understand <sup> and <sub? I cannot format non-standard fractions to look pretty.

I wanted to create a URL like http://localhost/menu.aspx/?id so that on typing this, it displays all the id's in the database. for eg:134
123
543
234
may be the id's which should be displayed after fetching from the database. However, it should be displayed as it it is without any control or without arranging in any gird etc. How can that be done?

I have a class Person that represents a person in my database. This class has a CategoryId property (int) and a Category property (type Category).
Category is a class that represents a category in my database. csharp Code:
public class Person{ public int Id {get; set;} public string Firstname {get; set;} public string Lastname {get; set;} public int CategoryId {get; set;} public Category Category {get; set;}} public class Category{ public int Id {get; set;} public string CategoryName {get; set;}}
[code]....
I am displaying a list of these Persons in a GridView, and I would like to display the name of the Category (the CategoryName property to be precise). So I define this markup;
xml Code:
<asp:GridView runat="server" ID="personsGrid" AutoGenerateSelectButton="True" AutoGenerateColumns="False" DataKeyNames="Id"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" /> <asp:BoundField
Usually I would solve this problem by one of two ways:Override the ToString method of the Category class and return the name.
Add a readonly 'CategoryName' property to the Person class, where I return 'this.Category.CategoryName' (and then bind the column to this property instead).
In this case however, I am using the Entity Framework, and the Person and Category classes are automatically generated by the database model. I suppose I could edit the generated code manually, but I don't like that, since any change in the model will cause VS to re-generate the code and my changes would be lost. So these two methods are not going to work...
The simple question remains: how do I make the Category column show the CategoryName property of the object it represents, rather than just the type name?In a DropdownList for example (which I am already using for the user to select a category when creating a person), I can set the DataTextField (to "CategoryName") and DataValueField (to "Id") properties and it displays the right name and uses the right value (the Id). I can't find anything similar for a BoundField though... Am I overlooking something obvious?
Another solution would be if I could tell the Entity Framework model to add another property to my Person class which returns the CategoryName of the Category. I can't find any way to do that though (I am a compleet noob in EF),

we have a program that we work with with in 2 different locations, both of the program instances must share the same database.what i did is to open Web Sharing folder on our server then i added on both computers this folder to their "My network places" and direct both of application to this folder which contains the database.this is how i direct the program :
Code:
D:WNKKWnkk.exe \MyServerktest
nk2008
it all works fine but there is one problem, the data pulling is pretty slow when it shouldn't we have 100MB download / upload on our server and over 10MB dl/ul in our office.
some pointers:i added the shared web folder to one of our website directory and thats mean that the port the program is using is 80
is port 80 is slower then others?

I have an asp.net app consisting of about 15 aspx pages and 30 or so user controls. For the most part it is just a basic CRUD layer on top of a database, so it consists mainly of edit forms and datagrids.
All of my edit forms are laid out in fieldsets, and I am using plain asp:GridViews for my tables (they render to an html table). Some forms are in serious need of tabs to lay out the elements. I'd really like to be able to style my GridViews with a fixed header and vertical scrollbars.
I have to do a demo in a few days but the problem is, there is no styling whatsoever applied to the html (no classes defined within the html, no CSS at all), and I am very weak with CSS.
So considering my predicament, can anyone offer some advice on how I could get this looking presentable in a very short period of time?
Is there such a thing as pre-existing decent generic CSS files I could download and drop on top of this app that could apply an attractive and consistent look and feel to most elements? Would http://jqueryui.com/ be useful in this particular situation?[URL] looks very attractive, can anyone comment on how easy it would be to globally wire all of my GridViews up with that?

I have a url that I want to map routing to:
[URL]
where tabvalue is one of: "personal", "professional", "values" or nothing.
I want to map it to a route like:
Member/Edit/{tab}
But my problem is - I don't know how to specify such constraints. I'm trying this regex:
^[personal|professional|values]{0,1}$
but it only works when I use url
[URL]
[URL]
and doesn't work for
[URL]
how to specify the correct constraint?
P.S. I'm not using MVC, just asp.net WebForms

I have very long select query which i need to filter based on some params, i'm trying to avoid having different stored procedures or if statements inside of single stored procedure by using partly dynamic TSQL.I will avoid long select just for example sake
select a
from b
where c=@c
or d=@d
@c and @d are filter params, only one can filter at the same time but also both filters could be disabled. 0 for each of these means param is disables so i can create nvarchar with where statement in it...
How do i integrate in here dynamic query so 'where' can be added to normal query. I cannot add all the query as big nvarchar because there is too many things in it which will require changes ( ie. when's, subqueries, joins)

What I need to do is selecting all data and then bind it into a gridview
To build a LINQ query, we need to drag the table into dbml file first. As we don't know how the table look like, can we add it in dynamically? Are there any other solutions?
