Namespace: DevExpress.XtraScheduler
Assembly: DevExpress.XtraScheduler.v23.2.dll
NuGet Package: DevExpress.Win.Scheduler
Declaration
Event Data
The AppointmentFlyoutShowing event's data class is AppointmentFlyoutShowingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets whether the appointment flyout is not shown. |
| Control | Allows you to set a control to display instead of default appointment flyout content. |
| FlyoutData | Provides access to data displayed in the appointment flyout. |
Remarks
The event arguments’ AppointmentFlyoutShowingEventArgs.FlyoutData property contains data for display in a flyout or using a custom control.
To add interactive elements into a Flyout panel (buttons, editors, etc.), either assign custom Flyout forms to the e.Control property or cancel the default Flyout and show a custom panel instead.
FlyoutPanel flyoutPanel = new FlyoutPanel();
XtraUserControl1 uc = new XtraUserControl1 { Dock = DockStyle.Fill };
//...
flyoutPanel.OwnerControl = schedulerControl1;
flyoutPanel.Size = uc.Size;
uc.Parent = flyoutPanel;
schedulerControl1.AppointmentFlyoutShowing += SchedulerControl_AppointmentFlyoutShowing;
//...
void SchedulerControl_AppointmentFlyoutShowing(object sender, AppointmentFlyoutShowingEventArgs e) {
e.Cancel = true;
flyoutPanel.ShowBeakForm(Cursor.Position);
}
Example
This code snippet substitutes an appointment flyout with a custom label control, as illustrated below:
scheduler.AppointmentFlyoutShowing += scheduler_AppointmentFlyoutShowing;
System.Windows.Forms.Label myControl;
Font myFont = new Font("Arial", 20);
public void scheduler_AppointmentFlyoutShowing(object sender, AppointmentFlyoutShowingEventArgs e) {
if(myControl == null) {
myControl = new System.Windows.Forms.Label();
myControl.BackColor = Color.LightGreen;
myControl.Size = new Size(200, 100);
myControl.Font = myFont;
}
myControl.Text = e.FlyoutData.Subject;
e.Control = myControl;
}
