All timing which all ExcelFunctions in the sheet are called automatically.

[김현욱]

Hello,
Thank you for your your support!
When we using UDF function (method which is marked as [ExcelFunction] annotation) , it seems for all UDF functions in the sheet to be called automatically in various case.
First time I thought that when some row or column deleted, when data filter of some item is applied or removed it's called.
But as my observation now, it's called when I just type any characters in any cell of sheet after registration of ExcelDnaXll64 (only first time after registration).

So I need to know in which cases, all ExcelFunction (method which is marked as [ExcelFunction] annotation) in the sheet are called for proper handling in each case.

Thank you!
