Custom Sorting - Ascending and descending

[Matias Puzanowski]

Hello Syncfustion Team!

I implemented a custom sort comparer for a date column with dd/MM/yyyy format, and is working perfectly for descending order, but how can I implement ascending order?

function sortDateComparer(a, b) {
    a = new Date(a);
    b = new Date(b);
    return a > b ? -1 : a < b ? 1 : 0;
 
}

Thanks in advance.

Hi Matias, 

Thanks for contacting Syncfusion support. 

We have validated the provided code example and We suggest you to use the below way to achieve your requirement. 

function sortDateComparer(a, b) { 

  a = new Date(a); 

  b = new Date(b); 

  return a > b ? 1 : a < b ? -1 : 0; 

} 

 

Help documentation: https://ej2.syncfusion.com/documentation/api/grid/column/#sortcomparer

Note: If a is less than b return -1 if a greater than b then return 1

Thanks a lot for replying and also for providing documentation, but I think that we misunderstood. Sort is working, but only in one way. 

Normal (ordered by IDs):

Descending (ordered perfectly):

Ascending (ordered just as descending):

So how can I do to sort in both ways?

Thanks in advance.
