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>
