Maybe

myTabControl.Items.Add(newTabItem);

Ah sorry, thanks for your response, but I wasn't clear in my OP.

I actually meant what would be the syntax for doing this in XAML? My XAML class derives from a class with the TabControl defined, how can I access it to add a new TabItem within my derived XAML or is this not possible?

TIA

Rich

Equivalent binding in code?

17-Nov-09 12:17

Maybe the ContentPropertyAttribute[^] is what you need.

There's an example using a List property here[^].

I think you could define a collection dependency property (or property
that implements change notifications) and use that as your control's
[ContentProperty]. That will allow you to specify multiple items in XAML.
Bind the ItemsSource of the embedded TabControl to that property.

There were some add-ins for WCF, WF and WPF development (I don't think they're accessible anymore). For WCF, you didn't really need to use the add-in though. Just having .NET 3.0 installed was enough.

Hi,

I'm in the process of refactoring some code I've inherited and as a part of this I need to re-create a binding which was previously in my WPF in code. The WPF snippet is:

<pre><TabItem Header="Notes">
<my:HelpEditor PlantId="{Binding Path=Id, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type my:Symbol}}}">
</TabItem></pre>

But I am now producing these TabItems in code so need to reproduce this binding in my code-behind file. In this case HelpEditor is a custom UserControl with a PlantId dependency property and Symbol is a custom object with a Id dependency property. HelpEditor needs to be bound to the Id in Symbol and so this WPF binding code works fine.

Here is the code I am trying to use in my code-behind file:

<pre>TabItem ti = new TabItem();
ti.Header = "Notes";
helpEditor = new ScadaAlarmViewer.HelpEditor();
Binding idBinding = new Binding("Id");
idBinding.RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(MyStuff.Symbol), 1);
helpEditor.SetBinding(MyStuff.HelpEditor.PlantIdProperty, idBinding);
ti.Content = helpEditor;</pre>

But this doesn't work, I get:

<pre>System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='MyStuff.Symbol', AncestorLevel='1''. BindingExpression:Path=Id; DataItem=null; target element is 'HelpEditor' (Name=''); target property is 'PlantId' (type 'String')</pre>

In the output window. If it's relevant, these TabItems are contained withint a Popup.

Can anyone help?

Rich

I think the problem comes from the fact that you are setting the binding before you have put the helpEditor into the visual tree. I think you will need to rearrange into something like:

TabControl tc = /* whatever tab control that will host the items */;
TabItem ti = new TabItem();
ti.Header = "Notes";
helpEditor = new ScadaAlarmViewer.HelpEditor();
Binding idBinding = new Binding("Id");
idBinding.RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(MyStuff.Symbol), 1);

//do these before setting the binding
ti.Content = helpEditor;
tc.Items.Add(ti);

//now that helpEditor is part of a visual tree with a Symbol ancestor, set the binding.
helpEditor.SetBinding(MyStuff.HelpEditor.PlantIdProperty, idBinding);

I think you're really confused. If your application contains the xls, how is it something that needs downloading ? It's already on the user machine. What do you mean exactly ?

Silverlight applications run on the client so it doesn't matter
what server you use, as long as the server can serve up .XAP files
and any other resources the Silverlight app may need.

Hey guys,

I'm developing a kind of website content management system. Users can drop 'blocks' of content on a page and some blocks are silverlight applications (for example picturebooks). I want users to be able to 'skin' the silverlight application like a css stylesheet would do that for a webpage. I was thinking of defining properties for objects used in the silverlight application (for example a button and an image) and let the user decide the values of the properties.

Is there a built in feature in Silverlight which allows me to create such functionality or do I have to write code for each and every property in silverlight which means a lot (A LOT) of coding...

Thanks!

You could merged dictionaries to provide alternate "skins" for controls.
Allowing the user to change them will require some coding definitely, because
you'll need to build dictionaries at runtime and probably need a way to save
the user's preferences.

The ImplicitStyleManager can help for applying styles to controls at
runtime so you don't have to do that part manually.

I see the following error while connecting to a wcf service through my silverlight application.

An error occurred while trying to make a request to URI 'http://localhost:3046/Service1.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.
