I am using GNU GPL - of dhtmlxGrid. and I am using findCell in my project. it was working good till yesterday. but same code is not working now.
is dhtmlxgrid_filter.js is Pro version ? if yes i can i worked some days.
findCell() method should work in a standard version of dhtmlxGrid.
Please, make sure that dhtmlxgrid_filter.js is included.
If issue still occurs for you - please, provide with any kind of sample of your code.
