January 9, 2015 at 7:31 am To have jqxgrid checkbox column in the column other than the first column. #65165
Hi,
I am developing a jqxgrid table having checkbox selection feature.I have a requirement where the checkbox selection column needs to be placed somewhere in the middle columns.By default
- selectionmode: ‘checkbox’
places this column as first column.
Is there any way where we can have this column other than the first column?
Thanks in advance 🙂January 9, 2015 at 7:54 am To have jqxgrid checkbox column in the column other than the first column. #65170Hello j2edev,
selectionmode: 'checkbox'
positions the checkbox selection column only at the beginning. If you wish to have the column elsewhere, you would have to implement a custom checkbox selection functionality, as shown in the following example:<!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" /> <script type="text/javascript" src="../../scripts/jquery-1.11.1.min.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxcore.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxdata.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxbuttons.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxscrollbar.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxmenu.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxgrid.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxgrid.edit.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxgrid.selection.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxgrid.pager.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxlistbox.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxdropdownlist.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxgrid.sort.js"></script> <script type="text/javascript" src="../../jqwidgets/jqxcheckbox.js"></script> <script type="text/javascript"> $(document).ready(function () { // prepare the data var data = preparegriddata(200); var source = { localdata: data, datatype: "array", datafields: [ { name: 'firstname', type: 'string' }, { name: 'lastname', type: 'string' }, { name: 'productname', type: 'string' }, { name: 'available', type: 'bool' }, { name: 'quantity', type: 'number' } ], updaterow: function (rowid, rowdata, commit) { // synchronize with the server - send update command commit(true); } }; var dataAdapter = new $.jqx.dataAdapter(source); var columnCheckBox = null; var updatingCheckState = false; // initialize jqxGrid.
