C# WPF System.OutOfMemoryException System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree

我已经在.NETFramework 4.5.1上构建了一个WPF桌面应用程序。它“通常”工作正常，但在某些机器上，在运行时显示WPF datagrid时会出现System.OutOfMemoryException

堆栈跟踪报告：

An error of type System.OutOfMemoryException occurred.

       in Microsoft.Windows.Controls.DataGrid.TryFindCell(Object item, DataGridColumn column)

       in MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)

非工作机器是32位、Windows7、2GB内存、.NETFramework 4.5.1

我必须说datagrid只显示很少的行。 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

有什么建议吗

谢谢

问题原来与运行帐户缺少某些特权有关

一旦用户通过启动可执行文件

右键单击，以管理员身份运行

问题消失了
