An application sends a ZGM_GETROWSALLOCATED message to get the number of rows that are allocated in memory for the ZeeGrid.
wParam = 0; //not used; must be zero
lParam = 0; //not used; must be zero
The number of rows allocated for the ZeeGrid.
A ZeeGrid might only have 30 rows of data, but could have 30 or more rows allocated in memory for additional row expansion. The ZeeGrid automatically resizes its number of allocated rows when needed to hold additional rows of data.
