Resources doesn't work at all?

Hi,

In the book WPF (O'REILLY) they have a simple example looking like this.

<Window x:Class="....

>

<Window.Resources>
<SolidColorBrush x:Key="Foo" Collor="Green" />
...
</Window.Resources>

<Grid Name="myGrid"> <!-- I have tried x:Name="myGrid" -->
</Grid>
</Window>

Code-Behind:

Brush b = (Brush)myGrid.FindResource("Foo"); <!-- This will not work, it
will throw an exception. -->

I have tried following things too.

Brush b = (Brush)this.Resources["Foo"]; <!-- Will not throw exception but
return value will be Null -->
Brush b = (Brush)this.FindResource("Foo"); <!-- Will throw exception -->

/Please help

Where in the code-behind did you try?
The line Brush b = (Brush)this.FindResource("Foo"); should work,
but maybe you have tried this in the constructor. Try with the code in the
Window's Loaded event.

Add loaded on the window , see below and the eventhandler Windowloaded in
the code behind

Window1.xaml :

<Window x:Class="WindowsApplication8.Window1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="WindowsApplication10" Height="300" Width="300"

Loaded="WindowLoaded"

>

<Window.Resources>

<Ellipse x:Key="shape" Fill="Blue" Width="100" Height="80" />



</Window.Resources>

<DockPanel x:Name="myDockPanel"></DockPanel>

</Window>



Window1.xaml.cs:

private void WindowLoaded(object sender, RoutedEventArgs e)

{

// Add button

Button myButton = new Button();

myButton.Content = "Click me!";

this.myDockPanel.Children.Add(myButton);

Ellipse myEllipse = (Ellipse)this.FindResource("shape");

this.myDockPanel.Children.Add(myEllipse);

}
