Change the Nextensio Default Column Sorting to DESC/ASC..

Post by jlig » 2012-05-15 22:44

One thing that has baffled me is how to change the default sort behavior of a Nextensio List to sort DESC first..

- For example, currently when you click a column heading, the list will first Sort Ascending..
- clicking the Column heading again, the list will Sort Descending..

Question: How do I reverse this to make it sort DESC, then ASC?

- I know the code for sorting is inside the TSO_TableSorter.cfc file in /includes/tso/ folder..
- I have tried changing some of the values in lines 58, 83, 97 but could not make it work in reverse..

Here is the code from the TSO_TableSorter.cfc.. notice the sections highlighted in Red..
- I tried various combinations/changes of DESC values to ASC, but it either gives no sorting at all, or has no effect..

I also have one instance where I would like to be able to do that.
Sorry I have no solution yet.
