c# - 如何使用mvvm在WPF中的DataGrid中的单元格中进行IsReadOnly更改

Question

我的网格如下。

我想要的是，如果选中了datagrid中的复选框，则选中True Holoday Name应该为True，否则应为可编辑。

<DataGrid CanUserDeleteRows="False" CanUserAddRows="False" Name="dgwCalenderDetails" SelectionMode="Single" ItemsSource="{Binding CalenderDetails, Mode=TwoWay}" IsReadOnly="False" AutoGenerateColumns="False" Width="770">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Day Id" Binding="{Binding DayId}" Visibility="Hidden" IsReadOnly="False" />
        <DataGridTextColumn Header="Day" Binding="{Binding DayName}" Width="100" IsReadOnly="False"/>
        <DataGridTextColumn Header="Date" Binding="{Binding DisplayDate, StringFormat={}{0:dd/MM/yyyy}}" Width="75" IsReadOnly="False"/>
        <DataGridTextColumn Header="Start Time" Binding="{Binding StartTime, StringFormat=N2}" Width="100" IsReadOnly="False"/>
        <DataGridTextColumn Header="Working Hours" Binding="{Binding NoOfWorkingHrs, StringFormat=N2}" Width="100" IsReadOnly="False"/>
        <DataGridCheckBoxColumn  Header="Holiday Status" Binding="{Binding IsHolidayYN}" Width="100" CanUserReorder="False"/>
        <DataGridTextColumn Header="Holoday Name" Binding="{Binding HolidayName}" Width="*" IsReadOnly="False" />
    </DataGrid.Columns>
        <Style TargetType="{x:Type DataGridRow}">
            <Setter Property="Background" Value="White"/>
            <Setter Property="IsEnabled" Value="True"/>
            <Style.Triggers>
                <DataTrigger Binding="{Binding IsHolidayYN}" Value="true">
                    <Setter Property="Background" Value="Gray"/>
                    <Setter Property="IsEnabled" Value="False" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </DataGrid.Resources>
</DataGrid>

<DataGridTextColumn Binding="{Binding HolidayName}" >
    <DataGridTextColumn.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="IsEnabled" Value="{Binding IsHolidayYN}" />
        </Style>
    </DataGridTextColumn.CellStyle>
</DataGridTextColumn>
