终于解决这个问题了，最根本的原因竟然是明细表格所在的那一行的Height为设置为Auto了，如下图所示：
把Height=“Auto”取消掉就行了。好逗逼的问题呀！！！！！！！！！！

非常感谢！我先把DockPanel给替换成Grid吧，至于上面那个问题，我之前的思路就是创建一个一行三列的表格，左边用来显示主单据列表，中间列用来显示分隔控件，右侧则显示单据的详细信息。所以，就把Grid.Row都设置为0了。

整体布局 改成 grid吧，别使用dockpanel， 分2行，第二行 再分2列， 左侧也可以使用grid分2行，下边的列表独自占一行。

一般整体布局 不适用dockpanel，而是使用grid。将grid分成列，行，再向里边添加控件。
贴个图，是赋值你的代码后的一个问题。
再检查检查代码

哎，本来想把代码一起此行都贴上去的，结果论坛最多只能录入10000个字符，只有发了几个帖子，确实比较凌乱。
按照我做的哪个demo来看，肯定是和布局有关系的，但是我也确实为显示明细的DataGrid指定了具体的行和列。
现在就是说不清楚到底是哪个布局设置出现了问题？难道是DockPanel和DataGrid套在一起就成这个鬼德性了？

这个是布局设置的问题，没有为显示明细的 DataGrid 指定具体的行吧，代码好乱。。。。

用Grid，宽度用auto，让DataGrid自动填充

但是，单独搞了一个DataGrid，竟然又能正常的显示，如下图：
