[DUG] Stringgrids

[John Bird]

Do you mean to sort by row or column?  I am guessing if you are swapping
rows you are sorting by a column
 
I have written a general routine to sort  any stringgrid by any two
specified columns, ascending or descending.  I would be happy to post it if
interested.  
 
I do it by using a temporary Tstringlist and dynamic array to load the
column values and original indexes into and then doing an alpha sort after.
It caters for a couple of data types, not just alpha sorting, so could
easily be extended to sort on various data types.  I think this way is
faster especially with bigger grids.
 
The only tricky issues were dealing with fixed rows/columns and whether to
keep the current row value after the sort.

Hi 

I havd a look, but can't see anything, but can you take 2 rows within a
TStringGrid and swap them? I have some details in a stringgrid but would
like to sort it on one of the rows after it has been filled. I can't fill it
in order to start with because the source data is coming from two different
sources.
