Occurs before a user inserts a dependency.
DependencyInserting: ASPxClientEvent<ASPxClientGanttDependencyInsertingEventHandler<ASPxClientGantt>>
The DependencyInserting event's data class is ASPxClientGanttDependencyInsertingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| cancel | Specifies whether to cancel the related action (for example, row edit, export). Inherited from ASPxClientCancelEventArgs. |
| values | Specifies the dependency values. |
Use the DependencyInserting event to process dependency data before a dependency is inserted.
Run Demo: ASPxGantt - Client-Side EventsRun Demo: MVCxGantt - Client-Side Events
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()
