URL Rewriting Based On QueryString Parameters
Apr 11, 2010
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?

My querystring has 2 parameters say pm1 and pm2. I want to check the value of each and if the value if '1' then pop open a new window(one for each parameter) and the url for the two windows will be different.

The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

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 going to be deploying an app in the near future on an IIS7 server, and would like to use the per-application URL rewriting settings in web.config, but this is not an ASP.NET application, so I have no need for anything superfluous.
What is the absolute minimum I need in my web.config in order to run my application and use URL Rewriting?

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
);
How can I make this work as described?

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)
How do I do this?

Which is the best way (in performance and security) to send multiple parameters to a web page (on a different server), considering that the length of the parameters may vary because I'm sending a list of products, and the customer may have selected more than one product, so we need to send each product on the querystring to the other page. For example (I'm on C#); I want to call a web page like this:
Simple Querystring: thepage.asp?Product=1&Name=Coffee&Value=1.99
Json: thepage.asp?{"Product":"1","Name":"Coffee","Value":"1.99"}
XML: thepage.aps?<xml><Products><product>1</product><name>Coffee</name><Value>1.99</Value></Products>
(Obviouly considering we can't send special characters via querystring, but I put them here for better understanding) Which will be the better way (performance, security)?

I'm using the iis7 URL Rewrite module and it's working fine, except for two things. Being new to this, I might be missing something obvious.
1) My URL gets converted from www.mysite.com/search.aspx?fName=John&sName=Smith to www.mysite.com/John/Smith. This works fine, but if I add a trailing / , a few images on the site disappear, wheras a few don't. (They're all in the same location). However, the search results are fine.
2) Is it possible to make cerain querystrings optional? Server side, this is implemented (i.e. if nothing is entered, then assume a default value). But how would this work with the URL rewrite module? e.g. www.mysite.com/John would search for John and use a default value for the sName parameter.

I've been rewriting a static site into a data driven version, and I want to do away with a specific page for custom errors. Is this possible?
eg:<customErrors mode="RemoteOnly" defaultRedirect="dynamic.aspx?w=1&p=5" />
When I run a page using the above config file, I get an error saying The requested page cannot be accessed because the related configuration data for the page is invalid. (it doesn't like the ampersand in the address)

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:
/somepage.aspx
/somepage.aspx?valueOfInterest=sausages
would become:
/somepage.aspx?valueOfInterest=wibble
And most importantly (perhaps) a request for:
/somepage.aspx?boring=something
/somepage.aspx?boring=something&valueOfInterest=sausages
would preserve the boring params to become:
/somepage.aspx?boring=something&valueOfInterest=wibble
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

In one of the web page say "Default1.aspx" I have a Gridview.I am using 2 DataKeyNames in Gridview. i.e., DataKeyNames="G_Name, Param_ID" Also, I have one Hyperlink inside Gridview, upon clicking, page navigates to other page say "Default2.aspx"
code of "Default1" page:Â
<asp:GridView ID="GridView1" runat="server" DataKeyNames="G_Name, Param_ID" AutoGenerateColumns="False" Width="100%" PageSize="8" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField HeaderText="Goal Name" DataField="G_Name" Visible="false"/>
[Code]....
code of "Default2" page:
protected void Page_Load(object sender, EventArgs e) {
if (!Page.IsPostBack) {
string name = Request.QueryString[0].ToString();
string id = Request.QueryString[1].ToString();
}
}
I want to pass multiple parameters in querystring. I wrote above code.
Problem is: I am unable to write the correct syntax for Hyperlink NavigationUrlTherefore, it is giving me below error:
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'GF_Name, Param_ID'.
at Line:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("GF_Name, Param_ID","~/Default2.aspx?Name={0}&Id={1}") %>'
Text='<%# Eval("GF_Name") %>'></asp:HyperLink>
how to resolve it.

I have a repeater control that generates a dynamic menu in an unordered list format. I have given each <li> item an id that includes a value from my database to make them unique:
<li id="category<%adding in my dynamic value from database here%>"><a href="#">Some Link</a></li>
One of the values that gets added to my list ids will match my querystring, making it the current page. So therefore I would like to highlight this to the user by changing the css class of the relevant li element. In my code behind I have created a string variable that takes the querystring value and modifies it to match the id. So for example my variable is "category7" - and I also have an li item on my page with an id of "category" How would I go about matching these two things in my VB and adding a class to the li element where the id = my variable.
