WPF MVVM DataGrid 内容不适合行高变化

Question

我需要使我的行高可变，以便我可以允许某些行添加其他信息。设置RowHeight值似乎没有任何区别。DataGridTextColumn由于所有内容都已绑定 (MVVM) ，因此在 的级别没有要设置高度的值。

            <Border Grid.Row="1" 

      Grid.Column="1"              

      HorizontalAlignment="Right" Margin="9" Width="auto" Visibility="{Binding LogVisibility}" VerticalAlignment="Stretch">

        <DataGrid AutoGenerateColumns="False" VerticalContentAlignment="Center" ItemsSource="{Binding EventLog}" RowHeight="100" Background="White" CellStyle="{StaticResource cellStyle}" ColumnHeaderStyle="{StaticResource headerStyle}" CanUserAddRows="False">

            <DataGrid.Columns>

                <DataGridTemplateColumn Header="Type" SortMemberPath="CategoryDescription">

                    <DataGridTemplateColumn.CellTemplate>

                        <DataTemplate>

                            <StackPanel Orientation="Horizontal">

                                <Image Source="{Binding Image}" MaxHeight="15" MaxWidth="15" VerticalAlignment="Center"/>

                                <TextBlock Text=" "/>

                                <TextBlock Text="{Binding CategoryDescription}" TextWrapping="Wrap"/>

                            </StackPanel>

                        </DataTemplate>

                    </DataGridTemplateColumn.CellTemplate>

                </DataGridTemplateColumn>

                <!--<DataGridTextColumn Header="Type" Binding="{Binding CategoryDescription}"></DataGridTextColumn>-->

                <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>

                <DataGridTextColumn Header="Details" Binding="{Binding TypeDescription}" MaxWidth="400"/>

            </DataGrid.Columns>

        </DataGrid>

    </Border>

设置的值RowHeight="{x:Static sys:Double.NaN}"不会改变任何东西，而是看到截断的文本，如下所示：

是的，如果您为 DataGridTextColumn 添加带有文本块包装的自定义样式，这是可能的<DataGridTextColumn.ElementStyle>&nbsp; &nbsp;<Style>&nbsp; &nbsp; &nbsp; &nbsp;<Setter Property="TextBlock.TextWrapping" Value="Wrap" />&nbsp; &nbsp;</Style></DataGridTextColumn.ElementStyle>您只需要将 TextWrapping 添加为Wrap或WrapWithOverflow您可以在此处查看差异。另外要使其工作，您需要删除RowHeight或者您可以将其更改为RowHeight="100"至MinRowHeight="100"它确保您的行高至少为 100，并且如果文本不适合 - 该特定行的大小可以变长，但对于原始行高，它不能更改大小并且所有行的高度都固定为 100。顺便说一句，100 似乎太高了，可能 20-ish 会很整洁。试试这段代码，我还在 Justify 中添加了 TextAlignment 以防你发现它有用。&nbsp;
