WPF System.OutOfMemoryException System.Windows.Automation.Pe

我在。net框架4.5.1上构建了一个WPF桌面应用程序。它"通常"工作得很好，但是，在某些机器上，在运行时，一个系统。当WPF数据网格将要显示时，OutOfMemoryException。

堆栈跟踪报告:

An error of type System.OutOfMemoryException occurred.

非工作机器为32位，Windows 7, 2gb内存，。net framework 4.5.1.

我必须说数据网格只显示几行。我一直在网上寻找类似的错误，但我找不到任何合适的解决方案。

任何建议吗?

谢谢!
