Have been using Spread COM version 7.0.55 for many years but am puzzled as to why the Spread control behaves in a particular way. The scenerio is this:
In our software there is code that makes a call to SetFormula() using the value, “SUM(C2:C14)”. Visually the grid displays to correct total as a number, but when attempting to export the grid contents to an XLS file (via a call to ExportToExcel) the following lines appear in the corresponding log file:
3 15 167:Custom functions are not exported to Excel.
3 15 175:Excel does not support the Spread static text cell type. The value of the Spread cell has been placed in the corresponding Excel cell, but the cell formatting has been discarded.
What I read from the documentation:
“Formula - Excel uses the formulas from Spread, except as noted.
The following functions are not exported to Excel:
PMT (log message 163)
Custom functions (log message 167)”
.
.
.
Even though I know that “=SUM()” is a valid Excel formula, am I to believe that the Spread COM’s SUM formula is a custom formula and will not carry over to Excel as is? If so is there is some way within the Spread COM to have a formula totaling for a range of cells carry over as is to an Excel XLS file?
Any help is greatly appreciated.
