DependencyDelete

The RadGantt DependencyDelete is fired when a dependency collection is about to be deleted from the database through the provider.

DependencyDelete event handler receives two parameters:

  • sender is the RadGantt control instance.

  • e is an object of type DependencyEventArgs. It gives you access to the deleted Dependencies collection.

Example

<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnDependencyDelete="RadGantt1_DependencyDelete"></telerik:RadGantt>
protected void RadGantt1_DependencyDelete(object sender, Telerik.Web.UI.Gantt.DependencyEventArgs e)
{
    foreach (var dependency in e.Dependencies)
    {
        if (dependency.Type == Telerik.Web.UI.Gantt.DependencyType.FinishFinish)
        {
            e.Cancel = true;
        }
    }
}
Protected Sub RadGantt1_DependencyDelete(sender As Object, e As Telerik.Web.UI.Gantt.DependencyEventArgs)
    For Each dependency As var In e.Dependencies
        If dependency.Type = Telerik.Web.UI.Gantt.DependencyType.FinishFinish Then
            e.Cancel = True
        End If
    Next
End Sub
