RSS Viewer web part cannot view Sharepoint's own feeds?

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :C#

Using MOSS 2007, if I want to view a list or a blog as an RSS feed using the RSS Viewer web part, it fails with the error "An unexpected error occured processing your request.  Check the logs for details and correct the problem."


(The misspelling of "occured" is not mine, that's how the web part displays the error message...)


I understand that the RSS Viewer web part cannot view authenticated feeds, but I have Kerberos set up (no double hop issues) and I am not using a proxy server, so shouldn't this just pass the credentials on from the client?


The only thing I see in the log file is:


01/30/2008 16:12:01.90  w3wp.exe (0x1F44)                        0x125C SharePoint Portal Server       WebParts                       8imj Unexpected Exception in RssAggregatorWebPart:SurprisenPreRender...

XML Viewer web part and SharePoint list RSS feed doesn't work

Hello, When I want to use the XML Viewer web part and set the XML URL to an RSS feed from a SharePoint list I get this error: Cannot retrieve the URL specified in the XML Link property. For more assistance, contact your site administrator. The URL I'm trying looks like this: http://sp2010/_layouts/listfeed.aspx?List=%7B76FD9EEE%2D9354%2D444E%2DBE3C%2DA9AE2C4B2063%7D I've seen blogpost that discuss this and they say that this is because of a security issue and that I have to enable anonymous access in order to display the RSS feed. Is this the only option there is ? I don't want to enable anonymous access on my SharePoint site. Why can't SharePoint just request the RSS feed with the credentials of the logged in user ? Or am I missing something here?

format-number issues with the Data View Web Part in SharePoint 2010

I have a number column named @Year_x0020_1_x0020_Revenue in the data view web part in SharePoint Designer 2010. In the Xpath expression builder - @Year_x0020_1_x0020_Revenue previews "500,000" If I use the format-number in the Xpath expression builder ==> format-number(@Year_x0020_1_x0020_Revenue, '$#,##0.00;-$#,##0.00'), it returns NaN. Is there any reason? 

Data View Web Part in SharePoint Designer 2010

Is Data View Web Part (aka Data Form Web Part) in the SharePoint 2010 has changed from the SharePoint 2007 or Is it working differently in the SharePoint Designer 2010? In SharePoint Designer 2007, whenever you have data view web part on the page, there is little handle to click on the top right of the data view web part to show Common Common Data View Tasks. Also for each cell, there was a handle to show xsl:value-of tasks which was great for formatting. Is that option is gone in the SharePoint Designer 2010?

Data Form Web Part - Sharepoint Dropdown List as a field in Edit View - Possible?


Hi guys,

I'm building a Sharepoint page with a data form web part that uses custom SELECT and UPDATE statements with an SQL Server connection in order to retrieve and store records of information.

I'm getting along fine, records seem to update how they should etc, but I've ran into a problem with one thing: Sharepoint dropdownlists in 'Edit Template'

So the issue is this: if I replace a textbox field with a dropdown list that is populated with a separate SQL datasource, the dropdown list seems to be unable to show the current value of the field.

E.g. I have a dataview which has a field "FruitID", which I can update just fine by setting the ID value to different numbers. The SQL datasource uses the FruitID to display a list of all available Fruits, (e.g. 1 = Banana, 2 = Apple, 3 = Cherry, etc).

If i open the dataview in editmode, the default value in the dropdown is null, despite the real value of the field being "2", which should show "Apple" in the dropdown.

I can select a fruit and click save, and it will update just fine. But the initial display needs to show the correct value to start with.

Is there a custom binding I should be coding to make this work? I can't configure dropdown <items> on an individual level as they are populated from the SQL server. I can't set "SelectedI

As the second article in a two part series, Steven examines the attributes and details of a SharePoint 2007 application page, including the construction and feature deployment of the same page based project. Since this is a WSS level objective, as opposed to MOSS, you will not need MOSS to work with the code included in this project. Windows Server 2003, WSS, and Visual Studio 2005 are all that is needed, with no additional add-ons. He provides a detailed analysis of each step involved in the creation and deployment of the project.
