FrameworkContentElement.FindResource Method

public Object FindResource (
	Object resourceKey
)

public Object FindResource (
	Object resourceKey
)

public function FindResource (
	resourceKey : Object
) : Object

You cannot use methods in XAML.

Parameters

resourceKey

Key identifier of the resource to be found.

Return Value

Important:
If you call this method for a key that cannot be found, an exception is raised. If you do not want to handle exceptions for this case, you should instead call TryFindResource. TryFindResource returns a null reference (Nothing in Visual Basic) when no resource is found, and does not raise an exception.

If the resource is not found on the calling element, the parent tree is searched using the logical tree, in the same way that the tree would be searched if a resource were requested by key at run-time.

Typically you would immediately cast the return value to the type of the property that you were attempting to set with the returned resource value.

The following example finds a resource as defined in markup and applies it to a certain property of an element in response to a routed event.

void SetBGByResource(object sender, RoutedEventArgs e)
{
    Block b = sender as Block;
    b.Background = (Brush)this.FindResource("RainbowBrush");
}
