Examples

This example demonstrates how to use the SchedulerStorage.FilterResource event to filter resources shown within a Scheduler Control based on specified conditions. Specifically, the code below shows only the first three resources.

C#

using DevExpress.XtraScheduler;
// ...

private void SchedulerStorage_FilterResource(object sender, PersistentObjectCancelEventArgs e) {
    Resource res = (Resource)e.Object;
    // Filter the first three resources in a collection.
    e.Cancel = schedulerControl1.Storage.ResourceStorage.Items.IndexOf(res) > 2;
}

VB.NET

Imports Microsoft.VisualBasic
Imports DevExpress.XtraScheduler
' ...

Private Sub SchedulerStorage_FilterResource(sender As System.Object, _
                                            e As PersistentObjectCancelEventArgs)
    Dim res As Resource = CType(e.Object, Resource)
    ' Filter the first three resources in a collection.
    e.Cancel = schedulerControl1.Storage.ResourceStorage.Items.IndexOf(res) > 2
End Sub

XAML

<dxsch:SchedulerControl.Storage>
    <dxsch:SchedulerStorage FilterResource="SchedulerStorage_FilterResource"/>
