Web Forms :: URL Routing And DataPager Control - How To Rewrite App
Sep 13, 2010
we are using URL Routing so a path like
[URL] would be output like [URL]
we have a data pager on the page that ties to the list view.
the data pager when changing pages reverts the url back to the un-routed version (like[URL])
how can i re-write this back to something more friendly for my app
ideally it would be great to have it look sometihng like /news/page/2
i can use IIS 7's new re-write module - already using it to remove trailing slashes.

I am using System.Web.Routing with ASP.NET (3.5) Web Forms that will URL rewrite the following URL from
http://www.myurl.com/campaign/abc
http://www.myurl.com/default.aspx?campaign=abc
The code is as below:
public static void RegisterRoutes(RouteCollection routes)
{
routes.Add("CampaignRoute", new Route
(
"{campaign_code}",
new CustomRouteHandler("~/default.aspx")
));
}
IRouteHandler implementation:
public class CustomRouteHandler : IRouteHandler
{
public CustomRouteHandler(string virtualPath)
{
VirtualPath = virtualPath;
}
public string VirtualPath { get; private set; }
public IHttpHandler GetHttpHandler(RequestContext
requestContext)
{
if (requestContext.RouteData.Values.ContainsKey("campaign_code"))
{
var code = requestContext.RouteData.Values["campaign_code"].ToString();
HttpContext.Current.RewritePath(
string.Concat(
VirtualPath,
"?campaign=" + code));
}
var page = BuildManager.CreateInstanceFromVirtualPath
(VirtualPath, typeof(Page)) as IHttpHandler;
return page;
}
However I noticed there are too many things to change on my existing aspx pages (i.e. links to javascript, links to css files).
So I am thinking if there's a way to keep above code but in the end rather than a rewrite just do a Request.Redirect or Server.Transfer to minimize the changes needed. So the purpose of using System.Web.Routing becomes solely for URL friendly on the first entry.How to ignore the rest of the patterns other than specificed in the code?

I am using ASP.NET 2.0 on IIS6 therefore I can't use system.web.routing. I've tried a few URL rewriters but none did what I wanted.I basically need to transform (read/parse then redirect) URL 1 into 2 with minimum IIS configuration because I don't have the full authority to reconfigure web servers (i.e. ISAP on IIS6 or install 3rd party extensions/libraries). And I can't transform URL into 3 because all the physical links will break. [URL]

ASP.net 4.0 / IIS7.
I want to "alias" a single web form to appear as various extensionless urls. Given a form in my web root called "mySite.com/ColorWebForm456.aspx":
I want it served as multiple names, e.g., mySite.com/Color, mySite.com/Colour, mySite.com/Colors, mySite.com/Coler, etc., without creating folders and duplicate forms with those names.I never want mySite.com/ColorWebForm456.aspx displayed in the browser, it needs to display as mySite.com/Color, even if the user somehow acquires it and types in that exact ~.aspx address. The variations will account for several alternate or mis-spellings users might attempt - I don't want them "corrected", however. So, if a user types in mySite.com/Colour, the url is NOT rewritten to mySite.com/Color, but the same page is served via ColorWebForm456.aspx as the requested "mySite.com/Colour".
I've seen so many articles on this that I'm not even sure where this would be best handled: in Global.asax, IIS7 URL Rewrite, web.config, etc., and I'm not even sure this is technically a case of url rewriting or routing... ?

I have implemented my own IRouteHandler for URL routing. For files without extension it will try to load the filename as a Page from the Pages directory with:
return (IHttpHandler) BuildManager.CreateInstanceFromVirtualPath(path, typeof(Page));
However there are also images and css files (with relative paths) that need to be translated to the correct url. I try to service those files with:
try {
HttpContext.Current.Server.Transfer(fileName);
} catch (HttpException) {
throw new HttpException(404, "file not found");
}
This works fine (in Internet Explorer), however Firefox is giving me an error:
Styles.css was not loaded because its MIME type, "text/html", is not "text/css".
Is this caused by the Server.Transfer? What should I use to redirect the file? Response.Redirect is visible to the client.

I have a datapager control
<asp:DataPager ID="DataPager1" QueryStringField="pageid" runat="server">
The control works perfectly when the QueryStringField "PageID" not not encrypted. When it's encrypted the control no longer works. Is there a way to assign the page number in the back end? Is there a way to work with encrypted query string with this control?

I have a page where I use the ListView and DataPager.My listview is populated as a table where each row has a bit data a dropdownlist with some values and a link button. Now I am trying to pick out the selected value from dropdown list when I kick on my linkbutton. As long as I'm on page one, everything is woriking fine. But if I go to page three then I can not pick out the value I selected in the dropdownlist. I have tried to add a textbox in the listview and then I am able to get the value out I typed into the textbox independent which side I'm on.
Why can I pick out the value from textbox but not the selected value in dropownlist?
Here is a piece of my code:

is there a way to set datapager controlid to control in other page.
For example: we have 2 pages - page1 with datapager1 and page2 with listview and datapager2. If i put datapager2 in page2 and set pagecontrollid to listview everything is ok. i wonder is there a way to set programatically the same in page1 so we could get te pagecount for other page.
Web Forum is a perfect example - we have posts count, when we click on datapager in topics list, it redirects us on selected page with posts for selected topic (i assume its on other page).

I've been trying to marry up the listview and the Data pager with my own, Database class that pulls the information from the database.
I can display the information ok no problem, fortunately this time I know what the problem is, but I cannot figure out a way around the problem.
In my Page_Load event I fill out the listview accordingly:
[Code]....
The problem lies in the postback, I need to figure out a way get the information as to what state the DataPager is in so I could update the Query accordingly.
I know there is a StartRowIndex avaialbe but this does not get updated in the Page_Load event.

I have created an application in asp.net 4.0 and entity framework4 . I have also implemented the routing feature introduced with this version of asp.net.I have page which displays a list of products and the paging is taken care of using datapager control.Now, when the user selects a particular product (using the checkbox provided besides it), I show the selected product's name on top. As the user goes on selected products the product_names are added on top. This functinality I want to achieve using javascript. When the user switches between different pages to select a product the already selected product names should be retained between different pages. I want to implement this whole fuctionality using javascript.My problem is how do I retrieve the page index from the datapager so that I can retain the selected values.Is there any other better way of doing it. I had already faced numerous problems in using javascript because of the routing functioanlity. But still I first want to see if there is a solution using javascript.

I'm using a ListView (e.g topListView) with paged rows (using a DataPager). One of the topListView's features is when a user clicks on one of its rows, its SelectedValue property is used to populate a SelectParameter in another SQLDataSource control that populates another ListView (e.g. bottomListView). It's working fine. Even when the webpage first loads, the SelectedValue of first row of the topListView is successfully being used to generate content in the bottomListView.
However, when one of the DataPager's buttons is clicked, the SelectedValue seems to be ignored, and the bottomListView isn't refreshing. And yet, when you click a DataPager button again, it works. basically it's taking TWO clicks of the pager for the SelectedIndex to be read. I've tried assigning the SelectedIndex to 0 in the PagePropertiesChanged and PagePropertiesChanging handlers but no luck (even with calls to bottomListView.DataBind(); and/or SQLDataSource1.DataBind(); after index assignment).
assigning the index seems unecessary though, since top row content is being rendered correctly in a SelectedItemTemplate after clicking any DataPager button. to me that means the SelectedIndex is being set to 0 when the page is being re-rendered.

I have a datapager with next and previous buttons as so:
<asp:DataPager ID="dpFeaturedPager" PagedControlID="lvFeaturedTips" QueryStringField="ftpg" PageSize="1" runat="server">
<Fields>
<asp:nextpreviouspagerfield ButtonCssClass="featured-previous" PreviousPageText="Previous" ShowNextPageButton="false" />
<asp:nextpreviouspagerfield ButtonCssClass="featured-next" NextPageText="Next" ShowPreviousPageButton="false" />
</Fields>
</asp:DataPager>
When there is only one page available, the Next and Previous links are rendered as so: <a disabled="disabled">Previous</a> I have not seen this disabled tag before, and presume it's coming from the datapager control which I won't be able to control. As usual, this is fine on FireFox but on IE7 the Previous and Next text does not render correctly - it is outlined (what I would expect disabled to look like to be honest - but looks a bit ugly in the page!)

I've just taken my first stab at making a ListView, ObjectDataSource, and DataPager run in an AJAX panel.
I had trouble getting it to work until I removed the QueryStringField="page" attribute from the DataPager. This attribute causes the current page to be passed as a query argument in the URL. For obvious reasons, I guess that won't work when posting back using AJAX.
Now my question is if this hurts my SEO. When I used QueryStringField, the page links appeared as regular links with various query arguments. But now the links are just javascript. Haven't I hurt a search engine's ability to scan related pages?

I have got most of this code online, which does not quite work, can something like this be done to produce a button click event to indicate that a built in button on the datapager control has been pressed ?
DataPager Pager1 = ListView1.FindControl("DataPager1") as DataPager;
{
foreach (Control cPagerControls in Pager1.Controls)
{
if (cPagerControls is Button)
{
Button OnClick = cPagerControls as Button;
OnClick += new EventHandler(OnClickMethod());
}
}
}

Where can I control right url address when the page is routed, using new routing feature in asp.net 4?
I tried to catch wrong url in the OnPreinit(), but the error is already thrown.
Error: The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.

I have a Web application where i have added a reference to a RESTful WCF. I got the WCF url Routing to work in my webapplication by adding Inherits="RestService.Global" to the Web applications Global.asax.
<%@ Application Codebehind="Global.asax.cs" Inherits="RestService.Global" Language="C#" %>
But then i tried to create url Routing for the Web application and it does not work with the Inherits="RestService.Global" in the Global.asax. If i take it away it works fine. Is there a correct way to do this.
