Question

I am trying to adjust the start date of an ActiveGanttVC control by using the timeline's SetStartDate() function. An exception is thrown claiming that I am trying to change a read-only property of the control. However, in the demonstration project, that function can be called successfully.

Answer

Answer:

We are not seing this behaviour here with this code:


    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.StartDate = DateSerial(2008, 10, 22) + TimeSerial(0, 0, 0)
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.Interval = "1h"
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.SmallChange = 3
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.LargeChange = 24
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.Max = 96
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.Value = 0
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.Enabled = True
    ActiveGanttVCCtl1.CurrentViewObject.TimeLine.ScrollBar.Visible = True

Be sure to have at least version 2.7.0.0 of the control.
