WPF使用中知识点总结二

DataGrid的行,单元格根据绑定数据的变化,改变样式:

一 : 对行的样式添加DataTrigger,当Binding的State值为0时,行的Background,IsEnabled两个属性改变

 1  <DataGrid.RowStyle>
 2  <Style TargetType="DataGridRow">
 3  <Style.Triggers>
 4  <DataTrigger Binding="{Binding Path=State,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" Value="0">
 5  <Setter Property="Background" Value="Red"></Setter>
 6  <Setter Property="IsEnabled" Value="False"></Setter>
 7  </DataTrigger>
 8  </Style.Triggers>
 9  </Style>
10  </DataGrid.RowStyle>

二: 对单元格的样式添加DataTrigger,当Binding的State值为0时,行的Background,IsEnabled两个属性改变

 1  <DataGridTextColumn.CellStyle>
 2  <Style TargetType="DataGridCell" >
 3  <Style.Triggers>
 4  <DataTrigger Binding="{Binding Path=State,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" Value="0">
 5  <Setter Property="Background" Value="Red"></Setter>
 6  <Setter Property="IsEnabled" Value="False"></Setter>
 7  </DataTrigger>
 8  </Style.Triggers>
 9  </Style>
10  </DataGridTextColumn.CellStyle>
