使文本在具有多行的数据网格单元格中居中

Question

我有一个wpf数据网格，其中某些单元格中有一条多条线的描述未居中，只有一条线的单元格居中。

只是认为这是一个标准问题，不需要太多信息。

这是数据网格的XAML。

<DataGrid AutoGenerateColumns="False" Style="{StaticResource DataGridMainStyle}"
                 Name="dataGrid_clients" CanUserReorderColumns="False" CanUserSortColumns="False" IsReadOnly="True"

我相信，这是因为这些单元格的数据上下文本身已格式化。由于它是字符串，因此在将数据传递到DataGrid之前，请尝试在后面的代码中进行一些修整（并可能删除新行）。

另外，您有：

<DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=Description}" TextWrapping="NoWrap"  MaxWidth="500"
                        ToolTip="{Binding Path=Description}">
                    </TextBlock>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>

您尝试设置TextWrapping="Wrap"吗？最后，澄清一下，如果您想进行水平居中或垂直居中，则可以添加一些信息。
