No the models are not in the WCF service, they are in their own library. The WCF service has a reference to the model library, and so does the client application. When you create your WCF service reference, you just ensure it reuses the referenced model library (obviously you need to reference the model library before you create the service reference). That way the service proxy is using the same models as the client app, it doesn't make it's own proxy models.

I knew there would be a catch, this sounds simple but I'll bet there is a bunch of nasty gotchas just waiting to jump out.
You don't by any chance know of a sample set up like this that can be studied do you? And yes I'm asking to snd t codz plz 
It's Friday afternoon here so I'm off to a drinking hole, you have defined what I will be doing this weekend!

It would only take me half an hour or so to set something up. Is it alright for me to email a VS 2010 solution to you. If so just drop me an email using the email tag below and let me know your address.

OtherClass.Subscribe<someclass>(_ => KeepWorking = !KeepWorking);
KeepWorking is a bool
This works fine, but what is Lambda expression _ =>

Hi,
I'm facing a problem to bind a StoryBoard to a label in my WPF application.
My XAML lloks like this:
<Label Height="28" Margin="308,27,250,0" Name="PostingStatusLabel" VerticalAlignment="Top" HorizontalContentAlignment="Left" Foreground="ForestGreen" FontWeight="bold">
<ContentPresenter Content="Posting"></ContentPresenter>
<Label.Triggers>
<DataTrigger Binding="{Binding IsPendingPostExist}" Value="True">
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<StringAnimationUsingKeyFrames Storyboard.TargetName="PostingStatusLabel" Storyboard.TargetProperty="(Label.Content)"
RepeatBehavior="Forever" FillBehavior="HoldEnd">
<DiscreteStringKeyFrame Value="Posting" KeyTime="0:0:0.0" />
<DiscreteStringKeyFrame Value="Posting." KeyTime="0:0:0.25" />
<DiscreteStringKeyFrame Value="Posting.." KeyTime="0:0:0.5" />
<DiscreteStringKeyFrame Value="Posting..." KeyTime="0:0:1" />
<DiscreteStringKeyFrame Value="Posting...." KeyTime="0:0:1.25" />
<DiscreteStringKeyFrame Value="Posting....." KeyTime="0:0:1.5" />
<DiscreteStringKeyFrame Value="Posting......" KeyTime="0:0:1.75" />
</StringAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Label.Triggers>
</Label>
When I'm trying to run this application.I get XAMLParseExeption at the start of Label.Triggers tag.
Anyone?
Best regards,
Eli

Hi,
Thanks,it is working... 
I have one more question:
I'm trying to stop the story board when the trigger is being changed from true to false.
I've set the story board name,and trying to stop it like this:
<Storyboard x:Key="Storyboard1" x:Name="Storyboard1">
.
.
.
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding IsPendingPostExist}" Value="True">
<DataTrigger.EnterActions>
<BeginStoryboard Storyboard="{StaticResource Storyboard1}"/>
</DataTrigger.EnterActions>
<DataTrigger.ExitActions>
<StopStoryboard BeginStoryboardName="Storyboard1"/>
</DataTrigger>
</ControlTemplate.Triggers>
but when the trigger switches to false,I receive the following InvalidOperationException:
"Storyboard1 object Name found but it is not a BeginStoryboard object."
Is there something I'm missing?
Thanks again,
Eli

The reason is, you haven't named the storyboard part you think you have. The key here is that it's BeginStoryboardName - which tells you that you need to apply a name to BeginStoryboard. Add a name to BeginStoryboard, and then use this name in the StopStoryboard.

Hi All,
I am using the WPF ribbon Library in my application for getting a ribbon control attached in my application.
I need the functionality where I can trap the minimize event in ribbon and do some additional stuff of code in there.
But, to my surprise I could not find any property named Minimized in ribbon .. I could found out collapsed and Expanded but they were of no use.
Can some body tell me what does IsMinimize property correspond to. As,if I know for which property the minimize functionality is attached,I can then easily solve my problem statement.

Hey,
I have in my application(wpf) an Indicator for all Input Boxes, wich indicate if the box is a mandatory field or not, and changes his color if the Field is filled.
Now the product team would like to have this indicator even on radiobuttons, that means the indicator of the radiobutton should know if the others radiobuttons of the same group are filled or not to change the color to the right one.
We have a new requiredradiobutton control wich derive from the Original Control: RadioButton, and i have to programm the Indicator of the control something like that:
protected override void OnChecked(RoutedEventArgs e)
{
RadioButtonGroup myradiobuttonsgroup = this.GetRadioButtonGroup();
foreach(RadionButton rb in myradiobuttonsgroup)
{
if rb.IsChecked != true
rb.Indicator.Status = Status.NotFilled;
else
rb.Indicator.Status = Status.Filled;
}
}
Or Another way how i can handle that without puting the radiobuttons in a listbox or something.
Thanks a lot and Cheers.

The way I understand it, you want the indicator in the NotFilled state if none of the radio button within the group are checked and the Filled state if at least on of the radio button (within the same group) is checked.
If this is correct, then your code is most likely wrong, this way it will set the indicator status based on the last radio button examined. Do something like
rb.Indicator.Status = myradiobuttongroup.Any(p=>p.IsChecked) ? Status.Filled : Status.NotFilled;
(not tested, may need polishing)

There's no RadioButtonGroup in WPF/Silverlight AFAIK. Radio buttons are grouped by either using them in a single common parent element or using the RadioButton.GroupName property.

Yes that whats i mean, how can i get all radiobuttons of a panel/window with the same groupname?
|
|
|
|
|
Can't you use databinding between the indicators and the Indicator.Status property? That would be the WPF way...

Mark, i dont need for binding because i programm the logic in the control, anyway changing the indicator status isnt a problem.. what i need is how to find out all the radiobuttons if i have the groupname of one of them.

Iterate through the Panel.Children collection and check each elements type. If it's one of your radio buttons then check its GroupName property. VisualTreeHelper.GetChild[^] can help...

Mark's method of iterating through all the children is the only public method. Lots of us use a class thats available on the internet called VisualTreeExtensions that does essentially the same thing, but wraps that code in an extension method for you. A GetVisualDecendants<RadioButton>(); call would return all the radio buttons. You could expand that to include the group name. Pretty much the same thing as what Mark suggested though.
If you are willing to use reflection, all that information has already been collected. RadioButton has a private member: private static Hashtable _groupNameToElements; thats a HashTable of ArrayLists using the group name as the key.
Some purists may frown on accessing a base class's internal data since it can easily change, but honestly, in this case, I don't see that happening. I'd just derive a class from RadioButton and implement a method that accesses _groupNameToElements so in the slight 1% chance that Microsoft ever does change that, you only need to change one place.
EDIT: See Petes post for a good point about my _groupNameToElements method  .

Hoo boy, there's a big catch in sorting this that you need to be aware of. The Group Name is not a unique property. What do I mean by this? Well, suppose you create a usercontrol that consists of a group of radio buttons with a single group name, and then you apply that control in more than one location, then the group name would span ALL the radio buttons that contain this group name.
This is a "by-design" feature of WPF, which is intended to allow you to spread your radio buttons across multiple containers.
