virtual scrolling and "empty" rows

[staganyiParticipant]

By using virtual scrolling, I noticed that if all visible rows cannot be filled with data (after a filter for example), the grid will fill itself with empty rows. I have read a few posts that says this is by design (which is fine). Having said that, I’m using rowdetails in my grid and would like to prevent row expansion on these empty rows. I looked online and discovered the hiderowdetails api and implemented it successfully…except that it doesn’t work on the “empty” rows (expansion still occurs). I’m guessing this is a bug?

Hi staganyi,

The method hiderowdetails only collapses the row details, it does not disable or hide them permanently. Having in mind that the “empty” rows in jqxGrid are part of the widget’s behaviour, we do not consider this to be a bug. Unfortunately, we cannot offer you a solution to this issue, either.

Thanks for the reply Dimitar. I understand that the “empty” rows are part of the widget’s behavior, but why don’t they behave like a “regular” row then?

For example, I have the following code in my grid that essentially disables row expansion (done like this for testing purposes):

$('#jqxgrid').on('rowexpand', function (event) {
  $('#jqxgrid').jqxGrid('hiderowdetails', event.args.rowindex);
});

The code works for “regular” rows (you cannot expand the row), but it does not for “empty rows” (row expansion still occurs).

The image below shows the row with part number 160049 (that cannot be expanded) and the empty row below it that can still expand.

Maybe I misunderstood your explanation, but I would consider this a bug no?

Hi staganyi,

Thank you for your feedback. We will look into this issue and will try to improve the grid’s functionality in the future.
