An application sends a ZGM_DELETEROW message to delete a row in the ZeeGrid. If the row specified in wParam is less than 1, or greater than the number of rows in the grid, nothing happens.
ZGM_DELETEROW
wParam = (WPARAM)(int) iRow; //row number to delete
lParam = 0; //not used; must be zero
This message does not return a value.
