ASPxClientGantt.DependencyInserting Event

Occurs before a user inserts a dependency.

Declaration

DependencyInserting: ASPxClientEvent<ASPxClientGanttDependencyInsertingEventHandler<ASPxClientGantt>>

Event Data

The DependencyInserting event's data class is ASPxClientGanttDependencyInsertingEventArgs. The following properties provide information specific to this event:

Property Description

values Specifies the dependency values.

Remarks

Use the DependencyInserting event to process dependency data before a dependency is inserted.

Run Demo

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

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