How to customize the taskbar background in ASP.NET Web Forms Gantt?

Taskbar background can be customized with the following background properties,

• TaskbarBackground: changes the taskbar background color.
• ProgressbarBackground: changes the progress bar background color.
• ParentTaskbarBackground: changes the parent taskbar background color.
• ParentProgressbarBackground: changes 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.

ASPX

<ej:Gantt ID="Gantt1" runat="server” TaskbarBackground="#F2F2F2”
   ProgressbarBackground="#CCFFFF”  ParentTaskbarBackground="#6600FF”
  ParentProgressbarBackground="#FFCC00”>
           // ...
           // ...
</ej:Gantt>

Instead of changing a common background color for taskbars, specific taskbar’s background color can also be changed 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.

ASPX

<ej:Gantt ID="Gantt1" runat="server” QueryTaskbarInfo="taskbar”>
           // ...
           // ...
</ej:Gantt>
<script>
function taskbar(args) 
{
      if(new Date(args.data.startDate)> new Date("02/09/2014"))
      args.taskbarBackground="#00FF00";
}
</script>
