Keep Text in appointment in view

Hello, Patrick,

By default, the AppointmentElement text is positioned at TopLeft. Hence, it is normal if you scroll down a long-running appointment the text to be outside the view area. I would suggest you to increase the view area of your RadScheduler, if possible, in order to allow more hours to be visible and appointments to be shown. 

If you want to change the text alignment you can use the AppointmentFormatting event and set AppointmentElement.TextAlignment property to the desired value. If you need to track when the vertical scroll bar changes its value you can use the following approach as an example to achieve your goal:

SchedulerDayViewElement viewElement = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewElement;
viewElement.DataAreaElement.VScrollBar.ValueChanged += this.VScrollBar_ValueChanged;

bool updateTextAlignment;

private void VScrollBar_ValueChanged(object sender, EventArgs e)
{
    RadScrollBarElement s = sender as RadScrollBarElement;
    if (s.Value > 5)
    {
        updateTextAlignment = true;
        this.radScheduler1.SchedulerElement.RefreshViewElement();
    }
}

private void RadScheduler1_AppointmentFormatting(object sender, SchedulerAppointmentEventArgs e)
{
    if (updateTextAlignment)
    {
        e.AppointmentElement.TextAlignment = ContentAlignment.MiddleLeft;
    }
}

I hope this information. Let me know if you have any other questions.

Regards,
Nadya
