How to customize the taskbar background in JavaScript Gantt?

In JavaScript Gantt, you can customize the Taskbar background by using the following background properties.

• taskbarBackground: Used to change the taskbar background color.
• progressbarBackground: Used to change the progress bar background color.
• parentTaskbarBackground: Used to change the parent taskbar background color.
• parentProgressbarBackground: Used to change the parent progress bar background color.

The above mentioned properties are used to set the common background color for the taskbars in Gantt. The following code example explains how to set the common background color for the taskbars in Gantt.

JS

<script type=”text/javascript”>
       $(function () { 
       $("#gantt").ejGantt({ 
      // ...
             taskbarBackground: "#F2F2F2",
             progressbarBackground: "#CCFFFF",
             parentTaskbarBackground: "#6600FF",
             parentProgressbarBackground: "#FFCC00"
      // ...
            });
         });
</script>

Instead of changing a common background color for taskbars, you can also change specific taskbar’s background color by using queryTaskbarInfo client side event that is triggered while rendering taskbars in the Gantt.

The following code example explains how to change the specific taskbar’s background based on a condition.

JS

<script type=”text/javascript”>
       $(function () { 
       $("#gantt").ejGantt({ 
           // ...
                    queryTaskbarInfo: taskbar
           // ...
            });
         });
 function taskbar(args) {
      If ( new Date(args.data.startDate) > new Date("02/09/2014") )
      args.taskbarBackground="#00FF00";
}
</script>
