AssignmentDelete

Updated on Aug 24, 2026

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.

Example

ASP.NET

<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnAssignmentDelete="RadGantt1_AssignmentDelete"></telerik:RadGantt>

C#

protected void RadGantt1_AssignmentDelete(object sender, Telerik.Web.UI.Gantt.AssignmentEventArgs e)
{
    foreach (var item in e.Assignments)
    {
        //...
    }
}

VB.NET

Protected Sub RadGantt1_AssignmentDelete(sender As Object, e As Gantt.AssignmentEventArgs)
    For Each item As var In e.Assignments
        '...
    Next
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.
