How to restrict only to draw a specific task dependency type in ASP.NET MVC Gantt?

1 min read

In Gantt, by using “ActionComplete” client-side event with requestType argument as “validatePredecessor” and by disabling the “predecessorValidation” argument we can able to restrict drawing the dependency line to a specific type.

The below code snippet explains restricting the dependency line draw action for creating only the FS (Finish-to-Start) dependency type.

CSHTML

@(Html.EJ().Gantt("GanttContainer")
 
//..  
 
.ClientSideEvents(cs =>
{
cs.ActionComplete("actionComplete");
})
 
.Datasource(ViewBag.datasource)
 
)
@(Html.EJ().ScriptManager())
 
<script type="text/javascript">
 
function actionComplete(args) {
if (args.requestType == "validatePredecessor" && args.predecessorValidation)
args.predecessor.indexOf("FS") != -1 ? (args.predecessorValidation = true) : (args.predecessorValidation = false);
}
 
</script>
