VS2010 Silverlight 4 - Getting "Object reference not set to an instance of an object" when loading a

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :WPF
In Visual Studio 2010 I'm trying to use the Blacklight Controls (http://blacklight.codeplex.com/releases/view/37652) in my own project (and actually included the Blacklight.Controls project in my solution so that I could debug what was going on) and... after making all the XAML changes needed to incorporate the Blacklight navigation menu with my stuff in the innermost grid... everything compiled ok when doing a Build.  When I run it there's a reference to a resource dictionary in the XAML that fails with the object reference error above.  The XAML is as follows:       <UserControl.Resources>       <controls:ResourceDictionaryManager x:Key="ResourceDictionaryManager">       <controls:ResourceDictionaryManager.ResourceDictionaries>       <controls:ResourceDictionaryCollection>       <controls:ResourceDictionary Path="/Blacklight.Showcase;component/ResourceDictionaries/DavesGlossyControls.xaml">       <controls:ResourceDictionary.ResourceKeys>       <controls:ResourceKeyCollection>       <controls:ResourceKey ResourceName="GlossyBlackScrollViewer" />       </controls:ResourceKeyCollection>     &

Where is SilverLight Toolkit in VS2010?


I read somewhere that MS has integrate SilverLight Toolkit into VS2010. Where is it? I can't find it under Toolbox.

why can't i run silverlight w/ wcf in iis but VS2010 built-in ASP.Net development server?

 Both VS200 and IIS are in my local machine. Suppose they have the same permission. I create a silverlight4 w/ wcf ria service project. The project runs well in VS2010 built-in ASP.Net development server. It doesn't work well after i publish it to IIS. I only can see its static content but not the .svc. i try to browse the .svc, it always show HTTP 500 error. I doubt if i do not open the asp.net runtime setting sth in IIS? Thanks!

Namespace resolution issue when loading activities designed in VS2010 in rehosted WorkflowDesigner

Hi. I have activities that is made in VS2010, that are to be used in a rehosted WorkflowDesigner app. In the rehosted app I have a WorkflowDesigner, a toolbox with all the standard and my custom activities, and a property window. The problem occures when I load a composite activity that has reference to other custom activities (and that is drawn in the designer in VS2010). In the rehosted app the composite activity is shown almost as expected, except that all the referenced activities are shown in the designer as a red error message: "Activity could not be loaded because of errors in the XAML."  If I load the same activity in VS2010 it works.  If I remove the referenced activity in the rehosted app and adds it from the toolbox there, it works. If I draw the composite activity in the rehosted app from "the ground up", it works. If I compare the activity XAML that is saved in VS2010, and the activity XAML when opened, modified and saved in the rehosted app, I find differences in how namespaces are expressed: The Activity-XAML from VS2010 has namespace resolution at the top: xmlns:local="clr-namespace:WCFWorkflowPOC" The Activity-XAML from the rehosted app does not save namespace resolution at the top. If I add the activity in the rehosted app insted of in VS2010, it places namespace resolution

vs2010 silverlight designer error


Hi all,

After installing Visual Studio 2010 and Silverlight Tools for VS 2010, I tried to generate a new Silverlight project and got an error in the xaml designer. 

None of the .xaml files generated by VS can be opened in design mode.

I have the KB30319.348 installed. The error is reproduced below:



Value cannot be null.Parameter name: parentContext

at Microsoft.Windows.Design.Metadata.ReflectionMetadataContext..ctor(IMetadataContext parentContext) at MS.Internal.Host.ProjectMetadataContext..ctor(IMetadataContext platformMetadata, AssemblyReferenceProvider referenceProvider) at MS.Internal.Host.ProjectMetadataContext.FromReferences(AssemblyReferenceProvider referenceProvider) at MS.Internal.Designer.VSDesigner.GetMetadataForDesignerContext(DesignerContext designerContext) at MS.Internal.Host.PersistenceSubsystem.Load() at MS.Internal.Host.Designer.Load() at MS.Internal.Designer.VSDesigner.Load() at MS.Internal.Designer.VSIsolatedDesigner.VSIsolatedView.Load() at MS.Internal.Designer.VSIsolatedDesigner.VSIsolatedDesignerFactory.Load(IsolatedView view) at MS.Internal.Host.Isolation.IsolatedDesigner.BootstrapProxy.LoadDesigner(IsolatedDesignerFactory factory, IsolatedView view) at MS.Internal.Host.Isolation.IsolatedDesigner.BootstrapProxy.Loa

DataSources in VS2010 works for WPF but not Silverlight


In WPF, when I connect to an ASMX web service that I built, my DataSources pane shows all of the return objects and I can drill down on them and see the contents so that I can bind to my controls.

However, when I create the same service reference in a Silverlight 4.0 using .NET 4.0, the datasources pane only shows the return objects and I cannot drill into them to see their contents.

Am I doing something wrong or is there some difference in the way WPF and Silverlight handle ASMX web services?

Silverlight calling WCF service on IIS 5.1, deployed by VS2010



Hi everyone,

I just started to learn silverlight. I had no choice then to learn web deployment applications and WCF services.

So I created a Silverlight application calling a WCF services functions storing and retrieving informations on a Database.

So I installed IIS 5.1 on my XP Pro and I published the Web project using VS 2010. Everything is fine so far with some settings I made on IIS.

But when I run the aspx page the Silverlight code runs good except when it is time to call the WCF services functionnalities.

Nothing happen.

Calls to the WCF services don't work. I cannot figure out why.

It's been hours I search on the net but nothing helps.

Thanks for your help.

Serving Silverlight Apps from Windows Mobile

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

Building a 3-Tier App with Silverlight 3, .NET RIA Services, and Azure Table Storage

Silverlight 3, .NET RIA Services, and Windows Azure Services Platform makes a 3-tier Cloud application easier to build: Silverlight 3 as presentation tier, .NET RIA services as the business logic and data access tier, and Windows Azure Table as the data storage tier. The sample application in this article demonstrates the architecture with a simple Survey application with all these technologies working together from Windows Azure.

Silverlight Simple Animation

Silverlight has several built in techniques for animating controls. Many of these technologies are particularly useful for creating simple animations meant to decorate a web page with eye catching movement that draws the reader's attention. In this post I will skip over these decorative technologies, and instead show how to create a simple animation using a technique similar to those used in many games.

Silverlight Slideshow Viewer for SharePoint

This series will walk through the Building Blocks that I have created to demonstrate and improve the SharePoint end user experience. I have been using many of these techniques in my developer focused demos for SharePoint 2010 (and in some cases SharePoint 2007). My plan is to use this post series to distribute my code and provide more detail on the why and the how of many of my code samples

Easier Silverlight Development against SharePoint

I have been spending quite a bit of time lately working with Silverlight 3 and SharePoint. One of the first big shifts for me is that Silverlight Development is Client development. Silverlight runs in the browser, but it runs on the client, so no SharePoint Object Model code. You have to access all of the goodness that is SharePoint through its web services.

JQGrid Loading deleted values



This is quite strange. here is the issue:

Some Info:

1. I'm using a multi-select jqgrid.

2. I have my own delete button to delete multiple orders

The problem:

When i press the delete button on the pager of my jqgrid, the records are deleted from the database but JqGrid shows some records (4-5). On refreshing the grid, correct numbers of records are shown.

Here is the code:

function delorder() {
        var amg = $("#horder").getGridParam('selarrrow');
        var cont = amg.length;
        if (amg.length > 0) {
