CGrid:GetNumCols

The GetNumCols method returns the number of columns in the current grid sheet. The number of columns may differ between sheets.

nCols = G:GetNumCols()

where

nCols is the number of columns in the grid. On failure, 0 is returned.

The following script creates a grid and increases the number of columns at a later time:

G = NewGrid(3,10)	-- new grid with 3 cols, 10 rows, 1 Sheet
Printf("cols = %d\n", G:GetNumCols() )	-- result: cols = 3
G:SelectSheet( 3 )	-- Select Sheet 3 (out of range)
Printf("cols = %d\n", G:GetNumCols() )	-- result: cols = 0 (sheet out of range)
G:GetNumCols( 8 )	-- change to 8 columns
Printf("cols = %d\n", G:GetNumCols() )	-- result: cols = 8
