free fork of jqGrid

======

jqGrid is a popular jQuery Plugin for displaying and editing data in tabular form. It has some other more sophisticated features, like subgrids, TreeGrids, grouping and so on.

jqGrid was developed mostly by Tony Tomov in the past and it was available under MIT/GPL-licences till the version 4.7.0 published Dec 8, 2014 (see here). Short time after that the license agreement was changed (see here) and new 4.7.1 version was published.

The code from the GitHib repository is the fork of jqGrid 4.7.0 - the latest version available under MIT/GPL-licences. It will be provided under MIT/GPL-licences.

Below you can find short description of new features and bug fixes implemented in free jqGrid 4.10.0 (compared with version 4.9.2). The version is developed by Oleg Kiriljuk, alias Oleg on the stackoverflow and OlegK on trirand forum.

Read Wiki for more detailed information about the features of free-jqGrid.

Free jqGrid can be used for free. We still ask to contribute the development by donating via PayPal, if one have the possibility for it. One can donate by clicking on the following button PayPayl donate button or by sending money via Paypal to oleg.kiriljuk@ok-soft-gmbh.com with the comment "free jqGrid".

One can install the package with respect of bower by using "bower install free-jqgrid", with respect of npm by using "npm install free-jqgrid" or from NuGet by using "Install-Package free-jqGrid".

Free jqGrid is published on cdnjs and jsDelivr CDN. So one can use it directly from Internet by including for example

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/free-jqgrid/4.10.0/css/ui.jqgrid.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/free-jqgrid/4.10.0/js/i18n/grid.locale-de.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/free-jqgrid/4.10.0/js/jquery.jqgrid.min.js"></script>

It somebody want to test the latest version of free jqGrid, one can load it directly from GitHib using RawGit service:

<link rel="stylesheet" href="https://rawgit.com/free-jqgrid/jqGrid/master/css/ui.jqgrid.css">
<script src="https://rawgit.com/free-jqgrid/jqGrid/master/js/i18n/grid.locale-de.js"></script>
<script src="https://rawgit.com/free-jqgrid/jqGrid/master/js/jquery.jqgrid.src.js"></script>

All other language files and plugins are avalable from CDN too. See the wiki article for more details about the usage of free jqGrid from CDNs and RawGit.

The package is published on WebJars and it's deployed on Maven Central too.

Remark: the above URLs will be available after publishing the release of the version of 4.10.0

Main new features and improvements implemented in the version 4.10.0.

  • New abortAjaxRequest method, which allows to abort pending Ajax request (before receiving the answer from the server). See the issue for more details.
  • New option threeStateSort:true is implemented. It change the default behavior on click on the column header. Instead of toogleing between ascending and descending sorting, it will be changed between three states: ascending, descending and unsorted. See the pull request and the demo for more details.
  • New option multiPageSelection:true is implemented. It works in combination with multiselect:true option. It allows 1) select some rows during loading just by filling the rowids in selarrrow parameter 2) the parameter selarrrow can hold now selected rows from multiple pages. Selection of some rows on one page, changing of the page, selection some rows on another page, returting to the previous page hold all previously selected rows. Sorting don't clear the selection. See the answer and the demo for more details.* New option maxHeight allows to set max-height CSS property on bdiv. The new option can be good combined with default height: "auto" option. For example the option maxHeight: 400 have no influence in case of small number of rows, but it reduces the maximal height of body of the grid (bdiv) to 400px, the grid get not so many place on the page and the user have to use horizontal scroll bar (created on demand). See the old answer for more details.
  • New option quickEmpty:"quickest" is implemented and is default. It improves the performance of rewdrawing the grid. One can use quickEmpty:true to switch back to the previous behavior and to use quickEmpty:false to get back to the behavior of jqGrid 4.7.
  • New options of editRow allows easy to implement starting of inline editing inside of onSelectRow or ondblClickRow and setting the focus on the cell which the user clicked. See the answer and the demo for details.
  • New callback subGridOptions.hasSubgrid is implemented. It allows to remove "+" icon of subgrid from some rows which definitively have no subgrids (have empty subgrids). See the answer and the demo for more details.
  • Essential improvement of performance of frozen columns espesially in scenario where the grid have many hidden rows (like data grouping with groupCollapse: true option in groupingView). The parameters of the event jqGridResetFrozenHeights allows to elliminate unneeded work. See discussion the pull request for more details. One can compare the performance of expanding/collapsing in the demo with the same demo, but which uses free jqGrid 4.9.2. One can increase the size of rows from 100 to 1000 for example (in getGridData(100)) and compare the both demos. One can compare the time for resizing the columns in both grids.
  • Essential improvement of performance of autoResizeColumn method used in autoResizeColumn and autoResizeAllColumns methods and in case of usage of autoresizeOnLoad: true option.
