将DataGridTextColumn的IsReadOnly绑定到DataGridTemplateColumn复选框IsChecked

问题描述

基本上，我有一个带有几列的 DataGrid ，并且我想启用（更改 IsReadOnly 属性）基于 CheckBox IsChecked 的 DataGridTextColumn ，位于另一个 DataGridTemplateColumn 与相同的 DataGrid 。

Basically, I have a DataGrid with several columns, and I want to enable (changing the IsReadOnly property) a DataGridTextColumn based on a CheckBox IsChecked, located in another DataGridTemplateColumn of the same DataGrid.

这里是（代码的重要部分：

Here is (the important part of) the code:

<DataGrid Name="lstTags" Grid.Row="0" ItemsSource="{Binding Path = LinesCollection}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False" SelectionMode="Single" LostFocus="lstTags_LostFocus" SelectionChanged="lstTags_SelectionChanged">
    <DataGrid.Columns>
        <DataGridTemplateColumn x:Name="colAutoScale" Header="Auto Scale">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <CheckBox x:Name="ckbAutoScale" HorizontalAlignment="Center" IsChecked="{Binding AutoScale, UpdateSourceTrigger=PropertyChanged}"/>
                 </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTextColumn Header="Scale" Binding="{Binding Path=Scale}" IsReadOnly="{Binding ElementName ckbAutoScale, Path=IsChecked}" Width="60" />
    </DataGrid.Columns>
</DataGrid>

值得一提的是，我还想反转IsChecked属性的值，即

It is worth mentioning that I also want to invert the value of the IsChecked property, that is

• IsChecked = true => IsReadOnly = false ;


• IsChecked = false => IsReadOnly = true

• IsChecked = true => IsReadOnly = false;
• IsChecked = false => IsReadOnly = true.

我可能会用一个简单的 Converter 来实现这一点，但是我需要

I would probably achieve this with a simple Converter, but I need that first part working tho.

编辑：

回答一个好问题，我的目标是禁用相邻单元格（同一行），而不是整个列。

Answering a good question, my goal is to disable the adjacent cell (same row), not the whole column.

推荐答案

对您的使用以下绑定> 规模 列：

 <DataGridTextColumn Header="Scale" Binding="{Binding Path=Scale}" Width="60" >
      <DataGridTextColumn.CellStyle>
           <Style TargetType="DataGridCell">
                <Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGridCellsPanel}},Path=Children[0].Content.Content.AutoScale}" />
           </Style>
      </DataGridTextColumn.CellStyle>
</DataGridTextColumn>

或简单地

OR simply

<DataGridTextColumn Header="Scale" Binding="{Binding Path=Scale}" Width="60" >
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="IsEnabled" Value="{Binding Path=AutoScale}" />
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
