Style

Style文件夹下新增资源字典文件ButtonStyle.xaml

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                     xmlns:local="clr-namespace:WpfApp6.Style">     <Style x:Key="myButtonStyle" TargetType="Button">         <Setter Property="Background" Value="#3a3a3a"/>         <Setter Property="Width" Value="50"/>         <Setter Property="Height" Value="50"/>         <Setter Property="VerticalAlignment" Value="Top"/>         <Style.Triggers>             <Trigger Property="IsMouseOver" Value="True">                 <Setter Property="Background" Value="Red"/>             </Trigger>         </Style.Triggers>     </Style> </ResourceDictionary>

　　

View改成 

<Button Content="{Binding ButtonContent}" x:Name="button1" Style="{Binding ButtonStyle}" >

同时View里增加对应的ResourceDictionary  

?

1 2 3 4 5 6 7 8

<UserControl.Resources>         <ResourceDictionary >             <ResourceDictionary.MergedDictionaries>                 <ResourceDictionary  Source="..\Style\MultiValueConverterResource.xaml"/>                 <ResourceDictionary  Source="..\Style\ButtonStyle.xaml"/>             </ResourceDictionary.MergedDictionaries>         </ResourceDictionary>     </UserControl.Resources>

　　

ViewModel增加

?

1 2 3 4 5 6 7 8 9 10

private Style buttonStyle;         public Style ButtonStyle         {             get { return buttonStyle; }             set             {                 buttonStyle = value;                 OnPropertyChanged("ButtonStyle");             }         }

　　

程序初始化时赋值

?

1	model.ButtonStyle = (Style)this.FindResource("myButtonStyle");

　　运行效果

 IsEnabled

View继续增加

?

1	<Button Content="{Binding ButtonContent}" x:Name="button1" Style="{Binding ButtonStyle}" IsEnabled="{Binding ButtonIsEnabled}" >

　　

ViewModel增加

?

1 2 3 4 5 6 7 8 9 10 11

private bool buttonIsEnabled;           public bool ButtonIsEnabled         {             get { return buttonIsEnabled; }             set             {                 buttonIsEnabled = value;                 OnPropertyChanged("ButtonIsEnabled");             }         }

　　

初始化时改值

?

1	model.ButtonIsEnabled = false;

　　

运行效果

其他绑定都是一样的，不再多说
