With "...MaterialDesign3.Defaults.xaml" in App.xaml you can no longer use mahapps:TextBoxHelper

[G-e-C-i]

Hello everyone,

I would like to use MaterialDesignInXamlToolkit with MahApps. I have also installed MaterialDesignThemes and MaterialDesignThemes.MahApps 5.2.1. But unfortunately I can't use the TextBoxHelper from MahApps.

For example:
<TextBox Width="200" mah:TextBoxHelper.Watermark="Watermark" mah:TextBoxHelper.AutoWatermark="True"/>

As soon as I use
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/materialdesign3.defaults.xaml" />

in the App.xaml, the watermark disappears. I have already tried the settings of Example and Integration but without success. Hence my question. What do I have to set so that I can use e.g. TextBoxHelper from MahApps?

Here is my App.xaml:

<Application x:Class="Prometheus.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
         Startup="OnApplicationStartup">
	<Application.Resources>
		<ResourceDictionary>
			<ResourceDictionary.MergedDictionaries>
				<!-- Theme setting -->
				<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
				<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
				<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Steel.xaml" />

				<materialDesign:BundledTheme BaseTheme="Light" PrimaryColor="LightBlue" SecondaryColor="Lime" />
				<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesign3.defaults.xaml" />

				<!-- Material Design: MahApps Compatibility -->
				<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.MahApps;component/Themes/MaterialDesignTheme.MahApps.Defaults.xaml "/>
			</ResourceDictionary.MergedDictionaries>
		</ResourceDictionary>
	</Application.Resources>
</Application>

Best regards and many thanks

I have found the solution. I have to use ‘materialDesign:HintAssist.Hint’ to get a watermark and not ‘Maheapps:TextBoxHelper.Watermark’. Then it works perfectly.

Thanks anyway and thanks for the great work, it really is a very good framework.
