Examples

This example illustrates how to handle the SchedulerControl's MouseUp event and use the SchedulerViewInfoBase.CalcHitInfo method to determine the visual element being clicked. If an appointment is hit, the method returns the AppointmentViewInfo object. To obtain the element under the mouse cursor, the AppointmentViewInfo.Items collection is analyzed. The coordinates provided by the Bounds property of a collection item are mapped to the coordinate system used in mouse events and subsequently compared with the cursor position.

private void schedulerControl1_MouseUp(object sender, MouseEventArgs e) {
    if (e.Button == System.Windows.Forms.MouseButtons.Left) {
        SchedulerViewInfoBase viewInfo = schedulerControl1.ActiveView.ViewInfo;
        SchedulerHitInfo hitInfo = viewInfo.CalcHitInfo(e.Location, false);
        if (hitInfo.HitTest == SchedulerHitTest.AppointmentContent) {
            AppointmentViewInfo info = (AppointmentViewInfo)hitInfo.ViewInfo;
            foreach (ViewInfoItem item in info.Items) {
                ViewInfoImageItem imageItemInfo = item as ViewInfoImageItem;
                if (imageItemInfo == null)
                    continue;
                Rectangle itemBounds = info.ConvertToVisualBounds(item.Bounds);
                if (itemBounds.Contains(e.Location)) {
                    using(var mb = new MyMessageBox(((ViewInfoImageItem)item).Image, "Got it!"))
                        mb.ShowDialog();
                }
            }
        }
    }
}
