CGridView:GetNumRows

The GetNumRows method returns the number of grid rows. Note that the number of rows is buffered to a multiple of 256. For example, if you request 50 rows using the GridParams table at the time of creation, the grid will actually get 256 rows. Similarly, creating the grid with 260 rows will result in a grid having 512 rows. To determine the maximum non-blank row containing data, use GetMaxRow.

Syntax
