Access values from xaml file in the code(View) directly

Question

I have a file (icons.xaml) that I added as a file in the Resources of my project. The file content is given below:

Icons.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<VisualBrush x:Key="Bucket"
             Stretch="Uniform">
    <VisualBrush.Visual>
        <Viewbox Stretch="xxxx">
            <Canvas Width="xxxxx"
                    Height="xxxx"> and so on...

Icons.xaml file's properties in vs 2017

Now, I want to consume the VisualBrush mentioned above, in my XAML (View) code directly. The lines are given below:

XAML Code (View)

<Setter Property="Icon">
    <Setter.Value>
       <Rectangle Fill="{Binding Bucket, Source={x:Static resx:Resources.Icons}}"/>
    </Setter.Value>
</Setter>

The "resx" namespace is defined as:

xmlns:resx="clr-namespace:MyProjectNamespace.Properties"

When I run my project I cannot see my icons being binded to the rectangle's fill property and I am getting some xaml intellisense error which is "Cannot resolve property "Bucket" in the context of type "string".

Objective: I want to use the visualbrush key directly in the XAML in my Rectangle's Fill property in my View code.

Note: I have a restriction that I cannot use the code in the view which is given below, I cannot use <ResourceDictionary> tab in the xaml code.

 <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/MyProjectNamespace;component/Resources/Icons.xaml"></ResourceDictionary>
    </ResourceDictionary.MergedDictionaries>
 </ResourceDictionary>

Am I following the right approach regarding my objective or should I change this approach?

I have seen the methods that are used here in this answer but none of them are working Get values from *.resx files in XAML

`icons.xaml` isn't a .resx file. what you need is StaticResource (or DynamicResource) ``. but you have to load "icons" resource dictionary first into MergedDictionaries of your view in your xaml code — ASh, Jul 03 '18 at 08:28
Ok, first I need to make it a resx file then I should carry on?. Because, I have a restriction to use Mergedictionary tabs (or words) in my xaml file — Newbie007, Jul 03 '18 at 08:32
I thought you need access to VisualBrush, not .resx file. I suggested how to get it from ResourceDictionary. "have a restriction to use Mergedictionary tabs (or words) in my xaml file" - no idea what this could mean — ASh, Jul 03 '18 at 08:42
Since you have a restriction to use Merged dictionaries, can you use local resources? — Lukáš Koten, Jul 03 '18 at 09:07
@LukášKoten Sorry for the late reply. No it cannot as I cannot use the words in the xaml and secondly, I only have usercontrol not winodws — Newbie007, Jul 03 '18 at 10:45
Well if you cannot use (for some reason) ResourceDictionary in xaml, you can still read them in code. — Lukáš Koten, Jul 03 '18 at 11:31
@LukášKoten Can i use this mergedDictionary in the code behind and use the resources in the xaml? — Newbie007, Jul 03 '18 at 11:46
Sure, you can read from MergedDictionary in code behind to access the VisualBrush and assign it to control you want (Rectangle), all from code. — Lukáš Koten, Jul 04 '18 at 06:46
@LukášKoten could you provide code for this, if it works I will mark it as answer — Newbie007, Jul 04 '18 at 09:06

I think the main issue here is that Binding is actually looking for a property called Binding on the Resources.Icons object.

Try this:

<Setter Property="Icon">
    <Setter.Value>
       <Rectangle Fill="{Binding Bucket, Source={x:Static resx:Icons}}"/>
    </Setter.Value>
</Setter>

If I write your code in the xaml, I receive error on the on the "Icons" word, saying "cannot resolve symbol 'Icons'" – Newbie007 Jul 03 '18 at 08:36

Binding is not necessary, just try:

<Rectangle Fill="{x:Static resx:Resources.Icons.Bucket}"/>
