SL app doesn't appear on web part

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :SharePoint

Hi there,

I'm trying to get my SL app to appear on a sharepoint web part, but it shows only an empty white page. Any other xap I try to display works fine. I have copied the xap to the appropriate folder. My application has compiled successfully as well. I tried debugging the web part by adding a breakpoint at the constructor of the mainpage. But it never gets there.

How can I troubleshoot my problem?

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?

Custom Web Part doesn't work with in anonymous access

Hi there, I have a custom webpart in a farm solution deployed to my site. Anonymous users should be able to view the site, however they can't because they are required to login due to the custom web part. If i remove the webpart from the page, anonymous users can view the site perfectly without the need to login. There is nothing really special about the webpart. It's a visual web part which uses the site and it's web data to display a sort of menu. Any idea? Thx in advance! Brecht

Web Part Page doesn't show current navigation

Hi! I'm having a problem with the navigation of web part page in Sharepoint 2010. For starters I need to say that I am a web designer and learning to brand Sharepoint 2010 wich means I'm not that tech-savvy so bear with me. We have created an intranet publishing site with Sharepoint 2010 and I have designed a custom master page with styles through Visual Studio 2010. The intranet site looks fine with the new design and I got navigation working with fly out menus, semantic subpages etc. The problem is: when I create a normal page the current sub-navigation is shown and it even shows my created web part page and all is fine, but once I go to this web part page, the left/sub-navigation disappears and I have no idea how to bring it back. The web part page uses the same master file as every other page. Everything with the the layout stays the same as my masterpage, except for the menu wich disappear so I thought it might be some property missing on the sub-navigation. Or do I need to edit something in the web part page layout in the gallery?: Master Page Gallery > BlankWebPartPage.aspx If so can I do it from Visual Studio? Here is the code for the left navigation menu: <!-- styles needed to have left nav to the left of the main area --> <div id="s4-leftpanel" class="s4-notdlg"> <!-- The quick launch bar / left navigation

WPF: If Heineken did MVVM Frameworks Part 4

MVVM is to have an instance of a particular Model (say currentPerson) inside my ViewModel (say PeopleViewModel) which is exposed to the View (say PeopleView). The View binds and edits the Model directly.

This definitely flies in the face of what most people consider to be the holy grail of MVVM pattern, but it's a fairly new pattern, so people are still finding their way with it every day, and this works for me very well. The reason I do what I do, is for the following reasons:

1.I have always had the luxury of being able to write my own UI specific Model classes. I would even do this if I was using some other Model classes first, such as LINQ to SQL or LINQ to Entity Framework. As these classes don't have everything a proper WPF Model class needs in my humble opinion. Though, they are pretty good, as they are Partial classes and use INotifyPropertyChanged/DataContract etc etc
2.I am a pragmatist and I do not like writing code for the sake of writing code. I have seen some MVVM apps where the author has had a Model with 50 properties on it, that are simply repeated in the ViewModel abstraction, where the ViewModel added nothing. On that day I decided I would never do that unless I have to.
3.I honestly see no harm in writing directly to the Model from the View, JUST SO LONG AS if the Model is InValid its data NEVER makes its way to the database. I honestly see no pro

Building Layered Web Applications with Microsoft ASP.NET 2.0 - Part 1

"Building Layered Web Applications" that shows you how to build N-Layer applications with Microsoft ASP.NET 2.0. These articles teach you how to design, build and use custom business objects in your web application. The target audience for this series are developers that are ready to make the switch from using SqlDataSource controls to ObjectDataSource controls with custom business objects. Experience with ASP.NET 2 and C# is necessary while some knowledge about object oriented design certainly helps. The design I am going to show you in these articles is a simplified version of a design you would use in a real world application. It doesn't feature all the necessary functionality your application needs, but instead focuses on the underlying concepts.

Hello World to C# Threading Part 1

In this post we will see how we can implement simple threading. Why do we need threading? When you want you application to do more then one thing at same time, then you need to implement threading. One usual and common scenario would be when your application needs to get data from some other resource like web services and you don't want you application GUI to be freeze during this time. In that sort of case you will run the code to access web services in separate thread so your application GUI won't freeze. The System.Threading namespace .NET provide interfaces to implement multi threading.

This post covers one such feature which is Routing in Webforms. Although Routing was available even in .NET 3.5 SP1, (check this excellent post by Phil Haack on implementing Routing in ASP.NET 3.5 with .NET 3.5 SP1), it was kind of less known. Also the plumbing work was too much for getting it implemented.

SharePoint Application and Site Pages - Part 1 of 2

In this first part of the two part series, Steven covers the differences between Site and Application pages in SharePoint 2007, why each may be used in various circumstances, and prepares for the construction of a menu located application page. After a brief introduction he examines the concept of Site Pages and Application Pages separately in detail with supported screenshots.

SharePoint Application and Site Pages - Part 2 of 2

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.

Choosing Between a User Control or Web Part for SharePoint

SharePoint will only display Web Parts on a page. However, there are publicly available shims that allow you to write user controls and have them be displayed as a Web Part. From SharePoint's point of view, the shim is a Web Part. From the point of view of the user control, the shim is simply a control in .NET that is including the user control
