Wpf find resource in merged dictionary in code

Creating resources with code. If you want to create an entire WPF application in code, you might also want to create any resources in that application in code. To achieve this, create a new ResourceDictionary instance, and then add all the resources to the dictionary using successive calls to ResourceDictionary.Add.Dictionaries can later be referenced using the Source property or by including them in a MergedDictionary. Sometimes the XAML you want to refactor can also contain some logic in code-behind, such as event handlers. By default, when you create a new resource dictionary, it comes without a code-behind class, but it's possible to add it.

Nice post, good set of information. I totally agree with you on your comments about WPF/XAML documentation and those people giving generalzed examples, no matter the number of incarnations of those examples. One thing that is really starting to grind my diodes is the lack of code infrastructure for resource dictionaries, datatemplates and such.

Hint: Our Style is only in scope if it is contained in the Resource Dictionary of the XAML file. This is the case if the style is declared directly in the Resource section in the XAML file. If it is declared in another Resource Dictionary it needs to be merged into the XAML file where we want to use the Style. Explicit WPF Style

See the following example: This is the official bug description from Microsoft: On the creation of every object in XAML, if a default style is present (i.e. style w/ a key of Type) that style should be applied. As you can imagine there are several ...
You can embed images into your WPF application as resources and then access them from code at run-time. To embed an image as a resource, add it to your project and set its Build Action to Resource. You can now access this image at run-time using a Uri.. The URI for a simple resource just includes the path to the image.

The following shows how you can get application-scope resources from the resource dictionary exposed by Resources in XAML. The following shows how you can also get the resources in code. There are two considerations to make when using Resources. First, the dictionary key is an object, so you must use exactly the same object instance when both ...
For WPF, these are all of your XAML files. They may be Windows, User Controls, or Resource Dictionaries. Though it is certainly possible to construct the view entirely from code, the vast majority of the UI will (and should be) built with XAML. The view may be quite dynamic, and even handle some user interaction (see the Commands section below).
The contents of the resource dictionary is a perfectly normal WPF style. The second step is to merge this resource stored in an external file into one of the resource dictionaries in our application. For this example we'll merge it in to the Application.Resouces collection (located in the App.xaml file). This is done by adding the elements ...
