Filter Problem

I am trying to apply filters on my grid but its shows the filter text(#text_filter) in header instead of text box, why I am facing this problem, really need your help guys.
Please see the attached image as well.


If you are using the 3.x version of the dhtmlxGrid you need to include the “dhtmlxgrid_filter.js” extension on your page.
Could you please, clarify what version of the dhtmlx you are using and what dhtmlx libraries are included on your page

Thanks its start working now. I forgot to add the library you have mentioned.
