How to change baseline color for specific tasks in a project?

Baselines are used to represent the original start date and end date of a task, scheduled at the beginning of the project. In Gantt, it is possible to render the baseline using RenderBaseLine property and we can define the baseline color using BaselineColor property at load time.

It is also possible to change this color dynamically for some task with the help of queryTaskbarInfo client side event.

The following code example shows you how to enable baseline and change its line color dynamically at run time based on condition in Gantt control.

  @(Html.EJ().Gantt("Gantt")
   .BaselineStartDateMapping("BaselineStartDate")
   .BaselineEndDateMapping("BaselineEndDate")
   .RenderBaseline(true)
   .ClientSideEvents(cl => {
                cl.QueryTaskbarInfo("QueryTaskbarInfo");               
    })
    //...
  )

<script>
        function QueryTaskbarInfo(args) {
            if (args.data.taskId == "2" || args.data.taskId == "3")
                args.baselineBackground = "red";
        }
</script>

The following screenshot shows the baseline in Gantt control.
