The RadGantt AssignmentDelete event is fired when an assignment's collection is about to be deleted from the database through the provider.

AssignmentDelete event handler receives two parameters:

  • sender is the RadGantt control instance.

  • e is an object of type AssignmentEventArgs. It gives you access to the deleted RadGantt assignments collection.


<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnAssignmentDelete="RadGantt1_AssignmentDelete"></telerik:RadGantt>
protected void RadGantt1_AssignmentDelete(object sender, Telerik.Web.UI.Gantt.AssignmentEventArgs e)
    foreach (var item in e.Assignments)
Protected Sub RadGantt1_AssignmentDelete(sender As Object, e As Gantt.AssignmentEventArgs)
    For Each item As var In e.Assignments
End Sub

Subscribing to only one of the following events: AssignmentInsert, AssignmentUpdate, AssignmentDelete, will cause a postback to be triggered for the other two events, instead of a callback.
