Question

How do you color a rectangle in C# that has been declared in XAML in WPF?

There is a rectangle control in XAML. In my C# code there are times in which it would be n

Answer 1

Wpf binding would be able to do this without having to reference the control by name in code:

<Rectangle Width="480" Height="200" Fill="{Binding Path=FillColor}"/>

Then put a property on your DataContext class, assuming you have implemented INotifyPropertyChanged:

public Brush FillColor  
{   
  get { return this.fillColor; }   
  set
  {
     this.fillColor = value;
     if (PropertyChanged != null)
     {
       PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
     }   
  }
}

Then you can assign your required color to the FillColor property and the UI will update itself.

For all of the people searching for this in 2019, I'm using WPF and you just add this property to your rectangle:

Your Rectangle should look something like this:

    <Rectangle HorizontalAlignment="Left" Height="75" Stroke="Black" StrokeThickness="4" VerticalAlignment="Top" Width="792"/>

Right before the forward slash, add in Fill="YourColorHere", for example, I'm using this: Fill="AliceBlue". IntelliSense should give you a list of colors to scroll through.
