C# Silverlight - Building a Timeline?

Does anyone have any good pointers for creating a custom silverlight timeline?! In fact it doesn't even need to be that custom, I have a database table and each object in that table has a datetime field called "CreateDate". I want to use this field to assemble a timeline, showing the other relevant fields at each specific CreateDate point........

Any tips? advice? help? samples?

Cheers

Implement your own Timeline Panel. Its quite easy!

Panels allow you to control layout generically for its children. The ItemsControl for example exposes a property called ItemsPanel that is of type ItemsPanelTemplate. By default this ItemsPanelTemplate contains a vertical StackPanel but can be overridden with your awesome Timeline Panel. They key to any timeline is the x-coordinate.

Using the code below to calculate your x coordinate is half the battle. After that its just a matter of determining overlap so you can properly stack your items on the timeline.

The Avanade Silverlight Accelerator has both a Timeline Control and a StackCalendar Control (think Gannt Chart) which work very nicely.

public double ScaleDate(DateTime date)
    {
        TimeSpan span = this.StopDate - this.StartDate;
        TimeSpan pos = date - this.StartDate;

        double posDays = double.Parse(pos.Days.ToString());
        double spanDays = double.Parse(span.Days.ToString());
        double x = posDays / spanDays;

        return x;
    }

The only one that I know of is this commercial control from Infragistics.
