Error on row select / pager Posts

August 21, 2013 at 5:52 pm Error on row select / pager #27304

Hello!

When using virtual mode and filtering, I then select a row. Event gets fired on row :

…(.on(‘rowselect’, function (event) {

var args = event.args;
var row = args.rowindex;

And row has the right rowindex.

When changing the page, event gets still fired, row had the correct rowindex but the selection does not happen in the grid and I get this javascript error :

TypeError: Cannot read property ‘uid’ of undefined [http://mysite.com/js/jqwidgets/jqxgrid.js:7]

I’m using 3.0.1. Did not have this problem in 2.9.2.

Thanks for checking this out.

Hi punkrack,

Sorry, but I do not see such issue: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/virtualdata.htm?web. The sample is with Virtual Grid and you can select rows on any page. Would you provide a sample which demonstrates your scenario?

Hi Peter,

In your example link, I cannot filter any column…
If you do not filter any column, there is no problem.

Try using a filter like filtering First Name : Nancy. And let me know if you did reproduce the problem.

If not, I will provide an example.

Hi punkrack,

Here’s a sample with Filtering and Virtual Data. In addition, I suggest you to check once more which version you use on your side.

Hi Peter:

Here is an example on how to reproduce the bug:

http://colligetest.ccdmd.qc.ca/test-jqxwidgets/test.php

I stripped down all the unecessary code I put. Grid starts on document.ready

1) When grid loads, select a row, it selects it on page 1.
2) Go to page 2, select a row, everything is fine.
3) Filter column ‘Modèle’, with contains ‘bio’
4) You get filtered results
5) Select a row, everything is fine.
6) Go to page 2, select a row, javascript error and row does not get selected EXCEPT the very first one on top.

Using version 3.0.1.

Waiting for feedback.

Thanks!

Here is an example with version 2.9.2

Everything is fine if you repeat steps above
