[vairam]

Hi
I want look like this in demo
http://demos.telerik.com/aspnet-ajax/scheduler/examples/timelineview/defaultcs.aspx but my problem is my control is dynamic control.
This is my code

_radScheduler.DataSource = dtFinalResult;
                _radScheduler.DataKeyField = "FieldID";
                _radScheduler.DataSubjectField = "LinkTitle";
                _radScheduler.DataStartField = "EventDate";
                _radScheduler.DataEndField = "EndDate";
                _radScheduler.DataBind();

                _radScheduler.TimelineView.GroupBy = "LinkTitle";
                _radScheduler.TimelineView.GroupingDirection = GroupingDirection.Vertical;
                _radScheduler.TimelineView.HeaderDateFormat = "MMM-dd";
                _radScheduler.TimelineView.SlotDuration = TimeSpan.Parse("1.00:00:00");


But in timeline mode i did not get any records. with out the bold lines in the above code i got the records in timeline mode what is the problem i have>
