Example

The following example illustrates how to cancel dependency insertion if the dependency’s predecessor task key is 10:

Web Forms:

<dx:ASPxGantt ID="Gantt" >
    <ClientSideEvents DependencyInserting="function(s, e) {
        if (e.values["ParentID"] == 10) {
            //...
            e.cancel = true;
        }
    }" />
</dx:ASPxGantt>

MVC:

@Html.DevExpress().Gantt(settings => {
    settings.Name = "gantt";
    settings.ClientSideEvents.DependencyInserting = "function (s, e) { 
        if (e.values["ParentID"] == 10) {
            //...
            e.cancel = true;
        }
    }";
    ...
}).Bind(
    GanttDataProvider.Tasks, GanttDataProvider.Dependencies, 
    GanttDataProvider.Resources, GanttDataProvider.ResourceAssignments
).GetHtml()
