AssignmentUpdate

Updated on Aug 24, 2026

The RadGantt AssignmentUpdate is fired when an assignment's collection is about to be updated through the provider.

AssignmentUpdate event handler receives two parameters:

• sender is the RadGantt control instance.

• e is an object of type AssignmentEventArgs. It provides access to the updated RadGantt assignments collection.

Example

ASP.NET

<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnAssignmentUpdate="RadGantt1_AssignmentUpdate"></telerik:RadGantt>

C#

protected void RadGantt1_AssignmentUpdate(object sender, Telerik.Web.UI.Gantt.AssignmentEventArgs e)
{
    foreach (var item in e.Assignments)
    {
        //...
    }
}

VB.NET

Protected Sub RadGantt1_AssignmentUpdate(sender As Object, e As Telerik.Web.UI.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.
