How to delete resource in AspxScheduler?

修改 AppointmentFormExPT.ascx 中的 控件 edtResource，添加事件 ondatabound

<dxe:ASPxComboBox  ID="cbReminder" ClientInstanceName="_dxAppointmentForm_cbReminder" runat="server" Width="100%" 

                       DataSource='<%# ((AppointmentFormTemplateContainer)Container).ReminderDataSource %>'

                       ondatabound="edtResource_DataBound" />

 

protected void edtResource_DataBound(object sender, EventArgs e)

       {

           edtResource.Items.RemoveAt(0);

       }
