Description

How to change the FirstVisibleTime of RadScheduleView when the active view definition gets changed.

Solution

Create a custom control that derives from RadScheduleView and override the OnActiveViewDefinitionChanged. Then reset the FirstVisibleTime property.

C#

	public class CustomScheduleView : RadScheduleView
	{
		protected override void OnActiveViewDefinitionChanged(ViewDefinitionBase oldValue, ViewDefinitionBase newValue)
		{
			base.OnActiveViewDefinitionChanged(oldValue, newValue);

			// reset the first visible time
			var time = this.FirstVisibleTime;
			this.FirstVisibleTime = TimeSpan.Zero;
			this.FirstVisibleTime = time;
		}
	}
