Hi All,
I wondered if someone could help me, to add additional parameters to a Style.
I've currently got a ContentControl, which has obviously has a "Background", "BorderBrush", "Foreground" & "Opacity Mask" brushes in the Properties tab. And I would like to specify additional brushes, that are contained within the Style.
The reason I want some additional brushes, is to define some Gradient Brushes. That I am using as an overlay for some of the components/parts of my inherited Control.
I can't seem to find anything on the web, but maybe I'm not looking in the right places!
One last thing, I'm a designer not a developer. - So presume I'm stupid to save time!!! ha ha
Thanks in advance!
Alan

What you could do is to bind your color to a property of your datacontext - something like -
<textbox x:name="MyTextBox" text="Text" foreground="{Binding Brush1, Mode=OneWay}">
You can then set your color through the code.
You could probably talk to a developer to see if this approach is useful to you.

Thanks, but I obviously did not make it clear:
I want to see this new brush, in the brushes section of the Properties tab of Expression Blend.
Something like this:

Thanks anyway.

Not sure, but maybe this[^] video may be of some help to you.

Thanks, but that still does not address or answer my question.

Hi Alan, you have probably figured this out by now. I haven't used Blend much but I think what you are looking for is that once you define your brush in Blend under properties, you can then click that tiny square 'advanced property options' and select 'Convert to new resource' which will then give you options where you want to place the brush. You will then have your new brush available under 'Brush Resources'.

Hi Katka,
Thanks for having a look at this, but it's a coding issue. (I am 99.99% sure!) 
I actually wanted this for my Picture Frame tutorial[^] to make it a bit funkier. And the reason is best explained there. I did drop a few hints, but no developer has taken the bait yet! 
Cheers,
Alan

Hi Alan,
I will have another crack at this 
You can add brushes to your style by addig them to your Resource Dictionary. Then you will have them available in Blend under 'Brush Resources'. For example if I were to add the six brushes, shown below, to the resource dictionary (PictureFrames.xaml) of your Picture Frame project, I would have all these brushes available in Blend under Brush Resources as shown here http://prikl.com/brush-resources.gif[^]
<!-- Primary Color Brushes -->
<SolidColorBrush x:Key="NavigationBackgroundColorBrush" Color="#FF282828"/>
<SolidColorBrush x:Key="NavigationForegroundColorBrush" Color="#FF595959"/>
<SolidColorBrush x:Key="HighLightColorBrush" Color="#FF747474"/>
<SolidColorBrush x:Key="HoverHyperlinkForegroundColorBrush" Color="#FFEBF7FF"/>
<SolidColorBrush x:Key="HoverHyperLinkBackgroundColorBrush" Color="#FF0096FF"/>
<SolidColorBrush x:Key="BodyTextColorBrush" Color="White"/>
Is this what you were after?

Thanks Katka, unfortunately not! 
As what I really want, is an extra Brush built into an inheritied Content Control. And then to convert this brush (on the fly) to 2 different resources (One of them rotated 90 degree)
This would allow me to edit the profile of my picture frame control in one spot, for both the Horizontal & Vertical Gradients. As currently, I have 2 resources that I reference. (just as you show)
Referencing 2 separate resources, means I have to copy setting from one to another...
It would just be really sweet to have this built in, as I'm finding this Control really handy, as you will see in my next tutorial...
Thanks for looking at this

I'm developing a WCF service and a client in a solution and when I use a service reference to the WCF in the solution that is added with FilePath (not IIS) everything works fine. However when I try to either add the service as an IIS website, or I publish the service then host under IIS and then add the reference, I'm getting the following error:
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ServiceModel.FaultException`1[[System.ServiceModel.ExceptionDetail, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]: Object reference not set to an instance of an object.

There's not a lot of help that we can offer you here I'm afraid. As you are already aware, this means that you are attempting to access a property/method on an object that is null. The details of where the exception is really happening will be in the InnerException, so that's where you need to look.

Using this excellent article[^] I am trying to set up a custom binding extension. The issue is that when the binding finds the source object, I need to do some stuff to the source object, but I don't know where to put that code. For example, I have the following class:
class MyObject {
public string Value { get; set; }
}
and some XAML in MainWindow.xaml:
<Button Content="{my:CustomBinding Value}">
And set the data context in code:
public MainWindow()
{
InitializeComponent();
this.DataContext = MyObject;
}
That much works, the Value string gets displayed on the button. But what I need to do is write code in the CustomBinding class that operates on MyObject as soon as possible, which means I need to resolve MyObject from the BindingExpression.
What I've figured out so far is that when the CustomBinding instance is created, it doesn't actually find the MyObject.Value because it needs to find the data context first in order to resolve the BindingExpression, so it doesn't actually find MyObject until the MainWindow gets laid out on screen.
So my question is, what code do I write in the CustomBindingExtension class so that it runs when the WPF layout system decides to resolve the BindingExpression to find MyObject?

For anyone interested, the answer turned out to be to hook into the DataContextChanged event of the targeted UI element (button1.DataContextChanged in this case).

Hi guys,
I am really new to WPF. I unerstand the concept of using Templates to create customization of a control, and i have attempted to change the visual behaviour of the Progressbar control and now hitting a brick wall.
So there are 3 things i would like to do:
1) Remove the 3d shiny part of the control - i dont like the 3d ness
I used control template to modify the foreground, i sucessfully killed the 3d shininesss, but moving part is expanding itself starting at the center point of the entire progress bar, and that it only expends to 100 pixels wide. this is because i set te Width=Value the foreground rectrangle's width attribute. How do i make it so that when the value = 100, the progressbar is fully filled?
<Rectangle Fill="{TemplateBinding Foreground}"
Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Width}"
Width="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Value}"
Margin="0,0" ></Rectangle>
2) Have a textbox following the top of the moving part to indicate a value - I have no idea how to do this
3) Make the whole control an arc, so that it looks like a fuel gauge - I know i can transform it,skew, size it whatever, but not warp it.
thx alot guys

what about a template just a guess, but a "like" that (warning: pseudo xaml code below)
template
grid
background
viewbox
grid with 100
rectangle LeftAlign with=Value
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

Hello,
I am new to silverlight.
I am planning to develope a Medical Imaging DICOM Viewer with one of the open source java api (say Image J).
And i am just thinking of Silverlight for the development of the UI part of the viewer.
Is the java api can be used in the Silverlight.SDK?
What about the rendering from other platform inputs?
Thanks in advance
Robin..

If your java API is exposed via a web service, then yes, you can easily call this directly in your Silverlight code.
If your Java API is not a web service, then, AFAIK, we don't have anyway to directly access them in Silverlight.

Could you please explain what you mean by 'other platform inputs'?

Hey guys, I was wondering, that almost 90% of Video on the web is in flash. How will that video be converted into HTML 5. Also, are there any good HTML Video editing tools.

This is the wrong forum for this question.
A better bet to get an answer would have been to post this question in the Quick Answers section.

Look, I appreciate that you want this information handed to you on a plate, but you were removed from the boards yesterday from posting exactly this type of question. You might want to do a simple Google search on this, and save people asking to remove you.
