If I use CalcEngine.LibraryFunctions.Clear() to remove all library functions... how do I add back in say the Sum or Round functions? Its the func parm of the AddFunction I am having trouble with!

Hi Peter, If you are only using a selected few Library functions, you may want to remove the unused ones. This will reduce the memory usage and may speed up parsing as well. You can use the method CalcEngine.RemoveFunction to remove even a single function. To remove all functions, you can clear the hashtable that holds them by using engine.LibraryFunctions.Clear(). After clearing all functions, you can add back the few methods you often employ. To replace a function with another implementation you must remove the original name and add the same name back with a different delegate method. Please take a look at the \Program Files\Syncfusion\Essential Studio\4.1.0.x\windows\Calculate.Windows\Samples\DataGridCalculator sample. In particular, a new function named Mymin is added to the function library in the SingleDataGridForm.cs or SingleDataGridForm.vb file. Also please refer Documentaiton section: Essential Calculate/Base/Function Library Best Regards, Jeba
