如何從源系結MaterialDesign的ButtonAssistCornerRadius值

我正在使用 C# WPF 和 Material Design 。

我需要的 ：

我正在嘗試為我的專案CornerRadius中ButtonAssist的任何一個設定。Button

問題：

我無法從Application.Resources.

我的 XAML：

<Window
    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:MaterialDesignation"
    xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
    x:Class="MaterialDesignation.MainWindow"
    mc:Ignorable="d"
    Title="MainWindow" Height="450" Width="800">
<Window.Resources>
    
</Window.Resources>
<Grid>
    <!--I Want to Set Radius For All Buttons in My Projects like blow line ↓-->
    <Button Content="Button" materialDesign:ButtonAssist.CornerRadius="30" HorizontalAlignment="Left" Margin="71,260,0,0" VerticalAlignment="Top" Width="237" Height="85" Background="#FF038BEA" BorderBrush="{x:Null}"/>

    
    <Button Content="Button" Style="{StaticResource ResourceKey=Gerdy}"  HorizontalAlignment="Left" Margin="410,129,0,0" VerticalAlignment="Top" Width="237" Height="85" Background="#FF038BEA" BorderBrush="{x:Null}"/>
    <Button Content="Button" materialDesign:ButtonAssist.CornerRadius="{Binding Gerdy}" HorizontalAlignment="Left" Margin="71,129,0,0" VerticalAlignment="Top" Width="237" Height="85" Background="#FF038BEA" BorderBrush="{x:Null}"/>

</Grid>

我的 App.xaml ：

<Application x:Class="MaterialDesignation.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          xmlns:clr="clr-namespace:System;assembly=mscorlib"
         xmlns:local="clr-namespace:MaterialDesignation"
         xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        
        <Style x:Key="Gerdy" TargetType="{x:Type Button}">
            <Style.Resources>
                <Style TargetType="{x:Type Button}">
                    <Setter Property="materialDesign:ButtonAssist.CornerRadius" Value="30" />
                </Style>
            </Style.Resources>
        </Style>

        <clr:Byte x:Key="GerdyAsByte">30</clr:Byte>

        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

為此基于 MaterialDesign 樣式創建自定義隱式樣式（不帶x:Key），并且僅更改. 它將自動應用于范圍內的所有 s。ButtonCornerRadiusButtonAssistButton

為您的按鈕樣式創建一個單獨的資源字典，以便在 MaterialDesign 的資源字典之后添加它，否則它們將覆寫您的樣式，而不是您覆寫其默認樣式。另請注意，本地值將始終覆寫樣式中的值。

<ResourceDictionary 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">
   <Style TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}">
      <Setter Property="materialDesign:ButtonAssist.CornerRadius" Value="30" />
   </Style>
</ResourceDictionary>

然后將它們添加到MaterialDesign 資源字典MergedDictionaries 之后。

<Application x:Class="MaterialDesignation.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
              xmlns:clr="clr-namespace:System;assembly=mscorlib"
             xmlns:local="clr-namespace:MaterialDesignation"
             xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>

           <clr:Byte x:Key="GerdyAsByte">30</clr:Byte>

            <ResourceDictionary.MergedDictionaries>
               <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
               <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
               <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
               <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
               <ResourceDictionary Source="CustomButtonStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>
