CGrid:GetNumRows

The GetNumRows method returns the number of rows in the current grid sheet. The number of rows may differ between sheets.

nRows = G:GetNumRows()

where

nRows is the number of rows in the current sheet. On failure, 0 is returned.

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

G = NewGrid(3,10)	-- new grid with 3 cols, 10 rows, 1 sheet
Printf("rows = %d\n", G:GetNumRows() )	-- result: Rows = 10
G:SelectSheet( 3 )	-- Select Sheet 3 (out of range)
Printf("rows = %d\n", G:GetNumRows() )	-- result: Rows = 0 (sheet out of range)
G:GetNumRows( 6 )	-- change to 6 rows
Printf("rows = %d\n", G:GetNumRows() )	-- result: Rows = 6
