  • Some issues in Virtual Mode with Ajax #64470

    It seems that using virtual mode Ajax with other functions performs some issues that are not reproduced with any other data binding methods (examples with local data, json data… work in all cases).
    I am experiencing some issues when combining some functions and data is loaded using virtual mode with Ajax:
    – Column Hierarchical Checkboxes: Uncaught TypeError: Cannot read property ‘length’ of undefined” (this has been posted by other users too).
    – Aggregates: no elements found to aggregate (total of a column of values)
    – Export data (html, json…): Uncaught No data to export
    – Paging and sorting works as expected.

    Maybe using “traditional” data loading like JSON data binding or JSON nested data binding won’t produce any incompatibility, but I don’t know if those loading methods will be optimal to manage over 50,000 rows (with a hierarchy of 3 levels) as I am intending to do.
    Could you advice any better way to manage these amount of data?
    Thanks!!

    Hi es3,

    1. The first item is posted in the Forums multiple times and is confirmed.
    2. You cannot aggregate something which is not loaded.
    3. You cannot export something which is not loaded.
