我不知道这是从哪里来的。以下是调试模式下的完整堆栈跟踪。如何找到根本原因？
跟踪堆栈跟踪没有说明错误的来源，内部异常遗憾地是空的。

Update1：使用
修复了该问题HeaderTeamplate = {StaticResource BALimitedHeaderTemplate}
而不是
<DataGridTemplateColumn.Header>
<ContentPresenter ContentTemplate="{StaticResource BALimitedHeaderTemplate}" x:Name="_BAContentPresenter"/>
</DataGridTemplateColumn.Header>
上面使用ContentPresenter的行是用户控件的一部分，该控件多次动态添加到父窗口。我仍然不确定，为什么将用户控件（单独的实例）添加到窗口导致异常 - 更奇怪的是仅在.Net framework 4.0 但不在4.5及以上。
更新2：显然这是Framework V4.0中的一个错误，使用似乎非常合法。 Framework 4.5及更高版本中已修复此问题！我们使用HeaderTemplate解决了这个问题。其他人试图在以下链接中描述此问题。
