You can use the MinutesPerRow property and TimeLabelRowSpan. There is a demo - http://demos.telerik.com/aspnet-ajax/scheduler/examples/customization/defaultcs.aspx
But Sir When We Set the MinutesPerRow property and TimeLabelRowSpan Rows Devide into Section but Still Time Shows in Left Side As 8am , 8am, 8am , 8 am and Then 9am, 9am, 9am, 9am and so On....
But I Want 8am, 8:15am, 8:30am, 8:45am, 9am, 9:15am, 9:30am, 9:45am, 10:00am and So On....

I see. Check the HoursPanelTimeFormat property - http://www.telerik.com/help/aspnet-ajax/telerik.web.ui-telerik.web.ui.radscheduler-hourspaneltimeformat.html
The property uses the standard .NET Date Formatting - http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
