Grid Summary Rows Throwing Error and Performance Issues
posted

Hello,

 

I have project in .Net Framework 4.5 using the latest Service Release of Infragistics WinForms 13.1. I noticed when moving to .Net Framework 4.5 all the grids with summary rows were taking longer to load.  I set Visual Studio to break on all exceptions and noticed that every Summary Row Calculation, while returning the correct data, is getting the error listed below:

 

PerCederberg.Grammatica.Runtime.RE.RegExpException occurred   HResult=-2146233088   Message=unsupported escape character: '\p{L}_]+' at position 1   Source=Infragistics4.Win.UltraWinCalcManager.v13.1   StackTrace:        at PerCederberg.Grammatica.Runtime.TokenRegExpParser.ReadEscapeChar()   InnerException:

 

I've attached a sample project that recreates the issue. Please advise as some of my forms have many grids with Summary Rows and the performance is now dreadful.
