If all you need to do is have one groupbox that behaves slightly differently to the others in it's styling, all you need to do is create a new style that targets a groupbox, and give it a key. By default, (as long as you add it after the groupbox above) it will inherit the settings of the groupbox, and you can change the background property as appropriate. All you need do then is apply the style to the groupbox in question - you have the key to use here.

This is exactly my question, how do I apply this specific style to the specific groupbox?

Have had troubles with WCF in Silverlight for two weeks Help!!!

Hi
I may have trouble to explain my problem but I will try. I have made a
Silverlight Application, in which I added a WCF Service. I added the
servicereference to the project. When I run it in VS it works great and when
I publish it in IIS it works great. But when I'm trying to deploy or what
it's called on the webserver, it gives me the error 405 . I can see in the web development helper that it doesn't download, or what that is called, the
clientaccesspolicy.xml. The clientaccesspolicy.xml and crossdomain.xml file
are placed in the root.

This is my web.config

 <system.serviceModel>
  <behaviors>
   <serviceBehaviors>
    <behavior name="AcceditWeb.Web.ServiceBehavior">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
  <services>
   <service behaviorConfiguration="AcceditWeb.Web.ServiceBehavior" 
name="AcceditWeb.Web.Service">
        <endpoint address="" binding="basicHttpBinding" 
contract="AcceditWeb.Web.IService">
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" 
contract="IMetadataExchange" />
   </service>
  </services>
 </system.serviceModel>
</configuration>

This is my ServiceReference.config which is placed in AcceditWeb.xap in the directory
ClientBin

<code>lt;configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>

maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
                <binding name="BasicHttpBinding_IService1" 
maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">

                </binding>

        <endpoint address="http://thewebsite.thewebserver.se/Service.svc" 
binding="basicHttpBinding"
          bindingConfiguration="BasicHttpBinding_IService1" 
contract="ServiceReference.IService"
          name="BasicHttpBinding_IService" />
      </client>
    </system.serviceModel>
</configuration>

This is my clientaccesspolicy.xml file

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="SOAPAction,Content-Type">

      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

This is my crossdomain.xml file

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="SOAPAction">

        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

Please help me, I have googled for two weeks now and tried the examples I
found, but nothing have helped.

Please I need HELP

You are publishing to an IIS server, correct?

Is the server you are publishing to configured for Silverlight[^]?

Is the endpoint address in your ServiceReferences.ClientConfig correct?

Can you connect to the service with the WCF Test Client[^] ?

Hi thanks for your answer.

Yes I think they are using IIS 5, as web development helper says.

I don't know if the server we are hosting to are configured for Silverlight.

I think the endpointadress is right. It has the adress where the service.svc is placed.
http://website.teliaweb.se/service.svc

No I can not connect to the service with WcfTestClient.exe. I get this error messages.

Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.

and

It looks like IIS isn't configured right to host the WCF service.

Are you able to get the Silverlight app or is an error returned there too?

Hi
I can run the silverlight application but when I'm using the wcf service I'm getting the error, nothing happens. I can see in the web development helper that the clientaccesspolicy.xml isn't reached. And the clientaccesspolicy.xml is placed in the root.

Thanks. It wasn't clear (to me) when you were getting the error.

fiaolle wrote:

I don't see anything indicating a cross-domain issue so I believe
that's irrelevant at the moment.

I don't think your WCF service is starting.

I've never used IIS 5 for WCF (or ASP.NET) so I'm no help with configuration.
Maybe Adam's link will help.

The error indicates a problem at the time the .SVC file is used, and since your
WCF service runs fine on your local IIS server, I don't think there's a problem there.
That's why I think there's an IIS configuration issue on the target machine.

WindowState.Maximized -- How to get the proper size of the window? [modified]

Cristoff13-Aug-09 22:01

Cristoff

13-Aug-09 22:01

I have a borderless window. A double click on it maximizes it - WindowState.Maximized and WindowStyle set to None.

Now I'm trying to get the proper size of that window so that I resize the internal controls.

My screen resolution is: 1280 x 800

SystemParameters.MaximizedPrimaryScreenWidth 1288.0 double
SystemParameters.MaximizedPrimaryScreenHeight 778.0 double

What are these two properties supposed to return actually? Why the width is larger than my screen and the other one smaller?

(on my screen visually the windows is OK)

---> Gets a value that indicates the height, in pixels, of a maximized top-level window on the primary display monitor.
---> Gets a value that indicates the width, in pixels, of a maximized top-level window on the primary display monitor.

???

Or

SystemParameters.FullPrimaryScreenWidth - 1280
SystemParameters.FullPrimaryScreenHeight - 744

What is the proper way to get the system metrics in WPF? Or there isn't one?

SystemParameters.VirtualScreenWidth
SystemParameters.VirtualScreenHeight

WPF Expander Control Template Modification

Hi,

How can I add dynamic image to the WPF Expander Control, so that, I can change it from the code behind.

I have created a CustomControl by inheriting the Expander control. I exposed a DependencyProperty named IconSource. I modified the HeaderTemplate by adding an Image.

Now my problem is, how can I change the source of that image inside the Header Template after the modification of the IconSource dependency property?

Can anyone please help me regarding that?

Can you bind the Image Source property to your IconSource property?

This is not a Silverlight problem. In the web.config file, you need the following section:

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="nnn" />
  </system.web>
</configuration>

Set nnn to be the appropriate size in KB.

It's with great pleasure that I announce the latest version of MoXAML Power Toys[^]. MoXAML now has the ability to translate your code from VB.NET to C# or vice versa, and to extract a user control directly from XAML.

Controlling the ObservableCollection rendering

Hi,
I have:
Class Persn with name and age props

class Manager with List<person> and event for any change occurs (name changed, person added to list etc.)

on the xaml.cs I have ObservableCollection with get to that list from manager. a listVier is bind to that observable

my problem is how to make the ui to refresh when that event of change is raised.

How can I implement that Observable and control the CollectionChanged?

thanks.

If u r using ObservableCollection & binded properly to the UI, then it will automatically refresh the UI thread as ObservableCollection automatically triggers INotifyPropertyChanged events.

So, no need to bother about it. Let me know, if you are facing any issue regarding the same...

(Please vote it as answer, if it helps you resolving the issue)

Re: Controlling the ObservableCollection rendering

Pete O'Hanlon14-Aug-09 1:13

It sounds like you've got your ObservableCollection in the wrong place. You need to change the List in Manager into an ObservableCollection, so that add and delete events are raised appropriately. Basically, you've wrapped the List up in something that will never see the changes without you explicitly raising a notification, which seems to be a little bit pointless.

Silverlight - VectrolLight Tree View

I have load a large set of data from SQL Server into a three level tree. It is taking long time to populate the tree.

Is there a way (e.g. lazy loading) to load only few records first and then load the rest of the records so that the tree area doe not remain empty for a long time.

Re: Silverlight - VectrolLight Tree View

Pete O'Hanlon14-Aug-09 4:18

14-Aug-09 4:18

The normal way to do this is to load all the items at the level you are at, and then add a dummy item to the level below. Then, when you expand your treeview you check to see if the first node below is a dummy node - if so, you remove it and attempt to retrieve data from the database that's a child of the expanding item.
