I can?t find
any doc for TTMSFNCGridBinder.
What is the use of it and what can I do with it?
This non-visual component can be used to connect multiple grid instances together and add inter grid formula calculating functionality. Drop TTMSFNCGridBinder on the form and add several grids on the TTMSFNCGridBinder.Grids.Grid, give each grid a name via TTMSFNCGridBinder.Grids.Name. Then you can use formulas with references : sheetname!cellref where sheetname refers to the name of other connected grids.
