Question

我有以下数据网格，如果网格设置为只读但不确定如何设置条件，我想为cover = false的行着色。问题似乎是第一个条件，其中cover = false，好像我删除了这个条件，另一个正在工作

        <DataGrid ItemsSource="{Binding AvailableRows}" AlternatingRowBackground="Lavender" Grid.Row="1"
                  IsReadOnly="{Binding IsEditable, Converter={StaticResource InvertedBoolConverter}}" CanUserResizeColumns="True">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding TabName}" Header="Tab Name" CanUserSort="False" Width="1.5*">
                    <DataGridTextColumn.ElementStyle>
                        <Style TargetType="TextBlock">

                        </Style>
                    </DataGridTextColumn.ElementStyle>
                </DataGridTextColumn>
                <DataGridTextColumn Binding="{Binding GroupSummaryTabRowDescription.Description}" Header="Benefit" CanUserSort="False" Width="2*" IsReadOnly="True">

上面我注意到，当您将Cover绑定到复选框列时，您使用转换器

Converter={StaticResource YNToBoolConverter}}

建议Cover属性不是布尔值。您是否在条件绑定上尝试了相同的转换器？

多触发条件不适用于datagrid？
