Question

我有两个单元格模板，一个用于“ ReadOnly”，另一个用于“ CellEditing”。按钮绑定了将变量（IsEditable）切换为true / false的命令。当我单击按钮时，直到双击单元格，样式才会改变。

我的问题是，如何动态更改DataGrid单元格样式而无需双击该单元格。

我的XAML：

<DataTemplate x:Key="ReadOnlyTemplate">
  <TextBox Text="{Binding ProductionName}">
    <TextBox.Style>
      <Style TargetType="{x:Type TextBox}">
        <Setter Property="IsEnabled" Value="False"/>
        <Setter Property="Background" Value="Black"/>
        <Setter Property="Foreground" Value="White"/>
      </Style>
    </TextBox.Style>
  </TextBox>
</DataTemplate>

<DataTemplate x:Key="CellEditingTemplate">
  <TextBox Text="{Binding ProductionName}">
    <TextBox.Style>
      <Style TargetType="{x:Type TextBox}">
        <Setter Property="IsEnabled" Value="False"/>
        <Setter Property="Background" Value="Black"/>
        <Setter Property="Foreground" Value="White"/>
        <Style.Triggers>
          <DataTrigger Binding="{Binding IsEditable}" Value="True">
            <Setter Property="IsEnabled" Value="True"/>
            <Setter Property="Background" Value="White"/>
            <Setter Property="Foreground" Value="Black"/>
          </DataTrigger>
        </Style.Triggers>
      </Style>
    </TextBox.Style>
  </TextBox>
</DataTemplate>

...

<DataGridTemplateColumn Header="Name" CellTemplate="{StaticResource ReadOnlyTemplate}" CellEditingTemplate="{StaticResource CellEditingTemplate}"/>

CellEditingTemplate仅在您已经编辑单元格时才应用。您想要的是在不编辑时修改样式。试试这个：

    </profile>
</profiles>

并将其用作CellTemplate。

<DataTemplate x:Key="ProductionNameTemplate" >
    <TextBox Text="{Binding ProductionName}">
        <TextBox.Style>
            <Style TargetType="{x:Type TextBox}">
                <Setter Property="IsEnabled" Value="False"/>
                <Setter Property="Background" Value="Black"/>
                <Setter Property="Foreground" Value="White"/>
                <Style.Triggers>
                    <DataTrigger Binding="{Binding IsEditable}" Value="True">
                        <Setter Property="IsEnabled" Value="True"/>
                        <Setter Property="Background" Value="White"/>
                        <Setter Property="Foreground" Value="Black"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </TextBox.Style>
    </TextBox>
</DataTemplate>
