The SchedulerAppointmentOperationEventArgs class includes the Appointment property that allows you to access the target appointment from event handlers.
You can also use the Cancel property in event handlers to cancel user actions. The following code snippet uses the Cancel property to restrict non-Admin users to add appointments to the DxScheduler.
<DxScheduler StartDate="@(new DateTime(2018, 10, 10))"
DataStorage="@DataStorage"
AppointmentInserting="(e) => AppointmentInserting(e)">
</DxScheduler>
@if (PopupVisible) {
<DxPopup HeaderText="Warning" CloseButtonClick="@(() => PopupVisible = false)">
<p>You are not allowed to add new appointments to the scheduler. Please contact your system administrator for details.</p>
</DxPopup>
}
@code {
bool popupVisible = false;
bool PopupVisible { get => popupVisible; set { popupVisible = value; InvokeAsync(StateHasChanged); } }
void AppointmentInserting(SchedulerAppointmentOperationEventArgs e) {
if (currentUser.Role != "Admin") {
e.Cancel = true;
PopupVisible = true;
}
}
