Hi All,
I have a HTML table to which I am binding data using the JTemplates script and then after the "processtemplate" line I am applying the datatables effect - ".dataTables();"
Everything works fine - custom pagination,custom filtering etc. The only sore point is that I am unable to sort properly when I click a header.
I am having 10rows per page. When Page1 is loaded, sorting works correctly on any column. But when I goto next page and click on a column header to sort that column, It sorts the previous pages records and shows the top 10 rows of the sorting .
So on page 2, the default display will show records with SerialNumbers from 21 to 30. Which is correct. But when I click on the SerialNumber Header to sort it, I get 1-10 shown as the result. If I click the header again, I am shown 10-1 (descending order). So my current data of rows from 20-30 is totally lost.
Here is the code :
