I’m interested in creating a GanttChart. After a long search I found “dhtmlxGantt”

http://www.dhtmlx.com/docs/products/dhtmlxGantt/index.shtml

I tried the sample of dhtmlxGantt in

http://www.dhtmlx.com/docs/products/dhtmlxGantt/download/dhtmlxGantt.zip

My problem now is when I try to run my application the dhtmlxGantt give me a blank page because it can’t get some function from javascript file!

Here is my code:

    Are you calling the createChartControl function somewhere? I don’t see it in the code. Try adding:

    <script type='text/javascript'>
createChartControl('GanttDiv');
</script>

    after you define the function and the div.
