Hi, I've written the WorkbookEvents_SheetCalculateEventHandler event to trigger for recalculation in Excel in C#.net2.0public event Excel.WorkbookEvents_SheetCalculateEventHandler SheetCalculate;SheetCalculate = new Excel.WorkbookEvents_SheetCalculateEventHandler( ThisWorkbook_SheetCalculate);The function Workbook_SheetCalculate(object Sh) triggers when there is a formula change in the excel sheet. My aim is to read the function result from the Sh object.for example, if A1=15, A2=17 and A3=SUM(A1,A2).Now I change the A1=17 so now I A3 value also changed because we write function for that.I want Capture that A3 Value also.Workbook_SheetCalculate fires as soon as there is change in A1 or A2. I need to read the function result. Please guide me to get the value off A3.Thanks in advance.
