ColorCanvas has 14 Binding Expression ErrorsΒ #4019
Description
Describe the bug
Using the MahApps ColorCanvas results in 14 binding expressions errors when the control is displayed. VS2019 shows them in the new XAML Binding Failures tool (Debug > Windows > XAML Binding Failures). Alternatively, you add a TraceListener via PresentationTraceSources.DataBindingSource (this is what we use during development to avoid binding errors).
Steps to reproduce
Create a new WPF application (I used framework, but probably doesn't matter) and use a ColorCanvas, e.g. using the sample code from the MahApps ColorPicker Documentation.
<Window x:Class="MahAppsDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:MahAppsDemo"
xmlns:mah="http://metro.mahapps.com/winfx/xaml/controls"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Grid>
<mah:ColorCanvas x:Name="ColorCanvasExample"
SelectedColor="Blue"
DefaultColor="Transparent"
LabelAlphaChannel="Alpha"
LabelBlueChannel="Blue"
LabelGreenChannel="Green"
LabelRedChannel="Red" />
</Grid>
</Window>Expected behavior
No binding expression errors occur.
Actual behavior
14 binding expressions errors show up (see screenshot below). Using a TraceListener in combination with Debugger.Break(); calls completely kills the development experience.
Environment
MahApps.Metro version: v2.4.3
Windows build number: Win10 2004
