Latest update available here (3/26/2006)
Please check out ASP.NET RSS Toolkit, one of my latest projects....

Hi Dmitryr, tell the guys of www.asp.net to update their links in the Sandbox page!

Dmitry,

It would be great if you could add "Conditional GET" / ETag support into your RSS Toolkit in order to greatly reduce the number of wasted bytes transferred that never really need to be transferred....

For details, see here:

http://fishbowl.pastiche.org/2002/10/21/http_conditional_get_for_rss_hackers

http://www.kbcafe.com/rss/rssfeedstate.html

That would make your excellent RSS Toolkit actually fully production quality!

Thanks
Marc

Thanks for the code, really appreciate it.

How about a vb port?
thanks
logic

OK, so I commented earlier BEFORE I tried the code, now I'm back to elaborate.  YOU my friend, are the man!  
Custom DataTypes based on the peculiarities of one feed vs. another?  Nice thinking, very nice.

I use the Geo namespace in my feed, and this little gem completely solved a problem I was beginning to tackle with the xmldatasource and the xpath stuff no more than an hour or so after you posted this.  JIT software releases!  I love it.  Thanks dude.

Oh, logic: use "reflector" to do your porting.

I already used the article you suggested for setting the MaxItems returned of an Rss feed.

But this is way more elegant. Many thanks!

Dimitry... any thoughts on adding support for the enclosure tag?

cheers and keep up the great work

how do i personalise the feeds?

Lot's of newgen feeds use the enclosure tags.  Also, I'd like to see an example of how to use the control specifying a custom xsl.  Is that possible?  I don't really like the formatting done with the datalist, but that's just a peculiar trait of mine, I guess.

Also, how does this support multiple namespaces included in various feeds as put out by google, feedburner, atom and the like? Maybe I'm missing the point and this is just for RSS types only.

Just a newbie, so don't hang me, just elighten me, please.

Oh, and thanks for the control, too.

I read somewhere that caching of the feed was configurable.  How's that done?

what profile apis should i call after i pass username to the populatechannel method for personalisation?

Dimitry,

This is kinda cool, but I see that you are simply using Dictionary <string,string> when you load attributes.

This unfortunately ignores all attributes in the RSS Feed - which undoubtedly is a serious downer.

For instance, this cannot be used for podcasts because the enclosures are enclosed under the "url" attribute of the "enclosures" element.

Just wondering if you're planning to address that anytime soon? :)

RE enclosure tags.. In answer to your question this is the whole basis for podcasting so yes, they are very widely used.  There is a directory of podcast feeds at http://www.podshow.com/directories.html and the itunes website has a similar directory each with thousands of example feeds.  The canonical example is probably Adam Curry's Dailysourcecode which is at http://radio.weblogs.com/0001014/categories/dailySourceCode/rss.xml

cheers

James

Dimitry, any podcast would have enclosures :)

Could any of you guys direct me to an example about how to create a data source in a ashx handler and to loop through records, surely that's the way to generate the feed automatically from a database isn't it?

I am new to 2.0 so kindly excuse.

Well I tried loading the channels dynamically the problem is
I can't instantiate the channel object, its unable to refer to the Channel Class..I added the .cs file in my app_code
I am usin the express edition of VS

back in the 1.x days we could use the using directive to refer to the proxy classes out here when I type using there is nothing in the intellsense for the proxy classes.

MsnbcChannel channel = MsnbcChannel.LoadChannel();

DataList.DataSource = channel.Items;

DataList.DataBind();

Dmitry,

In the next release it would be nice to see the RssDataSource control support virtual paths for the RSS data.  For example:

<rss:RssDataSource ID="WhatsNewData" runat="server" Url="~/news/newsfeed.xml" MaxItems="5" />

Thanks,
Colin

Dmitry,

I ran into an instance where the RSS has the dates from earliest to latest.  I didn't get a chance to look at the code yet, but do you have a way to alter the RSSDataSource so the items are reversed? In other words, if I set max items at 5, can it show me 2 from April and 3 from March instead of 3 from January and 2 from February?

Jason

Thanks for the pointer Dmitry. I'll look into that.

Also, thanks for creating such a useful tool. I had a library that operated close to this, but did not nearly include as much functionality.

This is just what I have been looking for to enable me to easily generate alerts from one of our internal systems management ASP.NET apps. Works a treat - almost.

The problem is that we have a site that uses Basic authentication over SSL. The authentication is no problem (from most RSS readers), however, I cannot use https as I get an error. If I then enable http access it works fine but obviously is not secure as Basic credentials are passed in the clear.

Is there a limitation with the toolkit here or am I doing something else wrong?

Simple List Extension (SLE), I am very interesting in building this into my generated feeds. Should it work with the toolkit and is there anything special I need to do to make it work?

I am so impressed so far, thanks very much for this.

Idea for your next version:

Dmitry,

Last night I was working with my app offline and I noticed that there is no error being handled where the download of the feed takes place in DownloadChannelDom() in RssDownloadManager.cs. I'll put one in for my own use, but it might be something you'll want to add in the future. I'm assuming in most instances, just kicking off an error might not be good because then the page would serve an error while it loads.

Jason

Dmitry,

Thanks for the response.

Just for clarity, when I mentioned HTTPS. it was in the context of generating RSS feeds using your toolkit, not in consuming other people's feeds. Anyway, I have done more testing and it seems that it is not a problem with the toolkit but with the reader. I tried "RSS Reader" and "RSS Bandit". However, it seems that HTTPS is fine from "GreatNews" and IE7 - I think!

As for SLE, I have tried but ot had any success yet. Please see http://blogs.msdn.com/rssteam/archive/2006/03/29/564154.aspx for an example of SLE, what it is, and how to add to your feeds. I want this to have "top 10" type lists.

Cheers,
Steve.

Dmitry,
I keep getting an error "failed to load RSS Feed for specified URL" when i try to configure the RssDataSource config form. Is this problem somthing to do with my internet proxy settings or is my toolkit not properly installed..

Dmitry,

Does the toolkit support publishing a feed with additional namespaces?

Cheers,
Mickey

Nice kit, very.

Interesting buglike behaviour in Firefox - when you put a RssHyperLink with IncludeUserName=True
and the page is posted back (eg put a calandar control on the page also and click a date or something), an error:

'/ClubWebSite/scenario5.ashx?t=A477EA...C13FD02C2' is not a valid virtual path.'

Any clue?

Hi,
What about to add a password string to method PopulateChannel(string channelName, string userName, <i>string Password</i>) for using with custom authentication? IMHO, it can be added the same way as user name...

I downloaded the zip file; then created a new Web site project in VS2005 on my local dev box that has .NET 2.0 framework installed.  Added a bin folder to that project and copied the DLL to that folder; then copied the scenario1.aspx file to my new web project.

But it won't build throwing 2 errors:

Element 'rssdatasource' is not a known element. This can occur if there is a compilation error in the Web site

and

Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.


Any pointers would be greatly appreciated.

Dmitri,

Did you look at my previous post on the Simple List Extension (SLE) ? I have not been able to get it working with the RSS Toolkit.

Thanks,
Steve.

One thing I discovered that seemed to "fix" the current problem... when I created new web projects in Visual Studio, I had been accepting the default location for them, which, in my case, happened to be "My Documents" located on a network share.  This seemed to cause the compiler all sorts of fits when it tried to build (don't know why really, but it would have to do w/ some sort of permission gremlins I'm sure!).

So, I created a new web project and made sure it was on my local hard drive, and then I was able to build the project successfully.

Unfortunately, I went from one issue to another.  When I ran the page, I got a nasty .NET error page, socket connection problems, etc.  We have a proxy server in our environment that all outbound IP traffic goes through, I'm sure that's the problem... but not sure how to work through it at this point...

I offer you great THANKS for releasing this toolkit to us and having it out in the wild!

Very nice work,

Any news on adding the "enclosure" tag support?

Thanks a lot, Dmitry.

Nach.

Hey, nice component thanks. but I sometimes get a problem if an RSS feed is selected that doesn't have a catagory tag, then RSS raises an exception when I try to read that property.

Please please please  .... Can you suggest a mod that would make rsstoolkit toolkit return an empty string rather than a null or an exception if a particular tag is missing.

Thanks

This tool kit is great. I have had great success in playing around with it. One question I have is when attaching to a datasource which has the image attribute, I am not sure in the datalist how to pull that field in the eval statement, like the other items are pulled in.

The item fields work fine, <%# Eval("title") %>, however, I am not sure how to pull in the image url in the header text.

Durant notre session Mini Mix à Toulouse aujourd'hui, un des participants avec qui j'ai parlé pendant

Is there anyway you could make the elipses default to the url associated with that particular blog entry.  I can use the String object to remove the elipses and add them back if necessary.  Thanks for the great control

Hi Dmitry,

Your work looks great, although I am having troubles 'installing' (and therefore using) it.

I am using:

Workstation:

-XPSP2

-VS2005 Pro

-.Net version=2.0.50727

Dev Server:

-2003Std

-.Net version=2.0.50727

First up, I've been coding for years, but still getting my head around dotNet (ie forgive me if I sound confused :P)

I attempted to install the RSSToolkit.dll using GACUtil (found in "C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin")

Result:

"Assembly Imported Successfully!"

However, when I create a datalist, and attempt to create a new DataSource for it, the RSSDataSource is not available from the list as shown on: http://aspalliance.com/ArticleFiles/919/image003.jpg

I have installed the RSSToolKit on BOTH the workstation's GAC and the DevServer's GAC, also rebooted both (just for sh!#$ and giggles) to no avail. I even created a bin folder in my site, and placed another copy of RSSToolKit.dll in there, but no joy.

Did I miss a step in the install process ?

Is this toolkit compatible with .Net 2.0.50727 ?

Do I need to include a "Imports RSSToolkit" type statement ?

What am I doing wrong :(

Thanks in advance,

Douglas

Hi Dmitry,

Thanks for the quick response :)

I set up a new website on the devserver, calling it: RSSTest

The web.config file was renamed to web.config.original

Then I copied the samples folder (including YOUR web.config) to the root of the RSSTest site.

The samples worked fine... Here's one of the headlines: http://www.msnbc.msn.com/id/15439415/

BUT...

The assembly does not appear in the list of .Net Components found in: Tools > Choose Toolbox Items... even though I installed it using the GACutil.

I sorted by namespace, name, assembly name etc, and entered 'rss' into the filter box, yeilding zero results.

Here are a couple of screenshots of the IDE: http://dug.mine.nu/dmitry

Thanks again ;)

Douglas

Fantastic!

All smiles here...

The only thing I hadn't done was:

* Click on "Browse..." and select RssToolkit.dll from where you installed it (not in GAC)

Thanks so much for your assistance ;)

Hi Dmitry,

I have an autopostbacking Drop-Down List:

   Names=Australian States

   Values=http://blah.com/feed.xml

I'm having a little trouble getting RSSDatasource to work as expected...

I can change the URL manually and it works, but if I use Page_Load... RSSDataSource1.URL = DropDownList1.SelectedItem.Value it doesnt.

I thought there might be some kind of RSSDataSource1.Refresh / Reload / ReFetch method ?

I Response.Wrote(DropDownList1.SelectedItem.Value) and the URL came up as expected, so the DropDownList / postback part seems to be working ok...

Can this be done ?

Thanks in advance,

Douglas

Hi Dmitry,

Thanks for the pointer. I made the change you suggested, but it didnt work...

I tried setting viewstate=flase in a number of places (page, other controls etc) before stumbling accross the AutoEventWireup="False" attribute in the page header.

I changed this to AutoEventWireup="True" and now its all working just the way I'd hoped :)

I'm now studying up on 'AutoEventWireup' :)

Thanks again for your assistance,

Douglas

Dmitry,

    I have created a feed with a ashx handler and a query string.  The feed can be read with IE7, but I cannot consume the feed with my own reader.  Using a RSSDataSource, I get an invalid characters in path.  I tried the late binding and I also receive errors.  Do you have any idea of where to start looking?  I have to add that I modified the RSSHTTPHandlerHelper to modify the encryption being used on the query string to use the sites authentication and encryption methods.  If I use the RSSHyperLink control it links properly to the handler which produces the feed and again it works in IE7.  

Thanks,

Carl

Great tool.

Just have a question.

I am using your toolkit to consume a RDF-source. Everything works great, manages to select everything from the source except items that have a node within the node.

Example:

<dc:items>

 <fileid>12453</fileid>

 <mime:type>pdf</mime>

</dc:items>

etc.

It just skips that node entirely. Is there a way or should I post a request at Codeplex?

Thanks in advance!

Hello,

I'm using this VS 2005 web project.  From what I've read the /Bin directory is still supported for backwards compatibility with ASP.NET 1.1 applications. Can i put the rsstoolkit.dll in one of the more appropriate directories within my web project rather than the GAC ?

If so, which one of the application directory [within my web project] can I use?

Regards

Ah

Hello,

Ops I might have been incorrect about the bin directory. Any

i've put the dll into the bin directory.

I link the control to a datalist and point the rsscontrol to the rss feed. I get a  {"DataBinding: 'RssToolkit.RssElementCustomTypeDescriptor' does not allow indexed access."}. This is without replacing datalist control with a hyperlink . Is this by design ?

Regards

Ah

Dmitry,

I've implemented your toolkit into our social website and it works great! However I do encounter one problem: we use ASP.NET Memebership to do the authentication, and we put a LoginStatus control on every page so users can login / logout. But I notice that if users logout on pages with a RSS control, they got a error says "something.ashx?c=channel' is not a valid virtual path. But if we remove the channelName property from the RSS control, everything's fine. Perhaps you could point out something I missed?

Thanks!

Dmitry,

I downloaded the file from CodePlex, which I think is the same as the file you posted here (1.0.0.1). The problem still persists. I noticed someone also reported here that postback will causing this error, so I tried selecting a day on a Calendar and the error occured. Did I download an older version from CodePlex (but I coldn't find a newer one) or this problem is not fixed yet?

Thanks!
