I was using the dhtmlxGrid in our company project.
I tried using the group rows by column option as shown in the example.
Howeveri get a javascript error saying “this._gmask is null or not an object”
I think it might be because of the sequence of the js file included in the page.
Please help.
Thank You
To use groupBy() method you should include dhtmlxgrid_group.js file to your page. Please find more information here dhtmlx.com/dhxdocs/doku.php?id=d … ct_groupby
I did include that file… but as I have included many files, i think the sequence has been affected.
