篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了具有多行的数据网格单元格中的中心文本相关的知识，希望对你有一定的参考价值。
我有一个wpf datagrid，其中在一些单元格中有一个描述，多行不会居中，只有一行的单元格中心很好。

只是认为这是一个标准问题，不需要这么多信息。
这是数据网格的XAML。

谢谢安德斯
答案
我相信，这是因为这些单元格的数据上下文是自己格式化的。因为它是字符串，所以在将数据传递到DataGrid之前，尝试在代码后面进行一些修剪（并且可能删除新行）。
另外，你有：
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Description}" TextWrapping="NoWrap" MaxWidth="500"
ToolTip="{Binding Path=Description}">
</TextBlock>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
你试着设置TextWrapping="Wrap"吗？最后，为了澄清，如果要进行水平或垂直居中，可以添加一些信息。
