[DevExpress Support Team: CLONED FROM Q469122: Removing the line of code "dx:ThemeManager.ThemeName="LightGray"" causes a cyclical exception with TextEdit control]
Hello,
I had this similar problem. I was working with VS 2012, and the installed version of Devexpress components is 13.2.9.
One of my forms has the following line of code: dx:ThemeManager.ThemeName="LightGray", but when i removed that i got OperationInvalidException which its message was "Cannot set OverridesDefaultStyle property in the default Style".
but when i changed its default theme, after of one compilation, I had no such problem! its weird!
It is difficult to localize the cause of this issue without additional information. Would you please post here a sample project to replicate this issue on our side? We will investigate it and try to find an appropriate solution.
