Horizontal Range Bar Chart bound to DateTime

[Josh Eastburn]

I'm working with the new Horizontal Range Bar Chart (http://demos.telerik.com/silverlight/#Chart/Gallery/RangeBar) and I'd like to bind the Low/High to DateTime properties.  Is this possible?  As I have it now, I get an invalid cast exception.

<telerikChart:RadChart x:Name="dateChart" Grid.Column="1" ItemsSource="{Binding DateCollection}" BorderThickness="0" Background="Transparent">
    <telerikChart:RadChart.SeriesMappings>
        <telerikCharting:SeriesMapping LegendLabel="DateRanges">
            <telerikCharting:SeriesMapping.SeriesDefinition>
                <telerikCharting:HorizontalRangeBarSeriesDefinition/>
            </telerikCharting:SeriesMapping.SeriesDefinition>
            <telerikCharting:ItemMapping DataPointMember="Low" FieldName="StartDate" />
            <telerikCharting:ItemMapping DataPointMember="High" FieldName="EndDate" />
        </telerikCharting:SeriesMapping>
    </telerikChart:RadChart.SeriesMappings>
    <telerikChart:RadChart.DefaultView>
        <telerikCharting:ChartDefaultView>
            <telerikCharting:ChartDefaultView.ChartLegend>
                <telerikCharting:ChartLegend Visibility="Collapsed"/>
            </telerikCharting:ChartDefaultView.ChartLegend>
            <telerikCharting:ChartDefaultView.ChartArea>
                <telerikCharting:ChartArea NoDataString="No Data Available"/>
            </telerikCharting:ChartDefaultView.ChartArea>
        </telerikCharting:ChartDefaultView>
    </telerikChart:RadChart.DefaultView>
</telerikChart:RadChart>

Also, I'd like to have each bar a separate color.  All of the bars are the same color since they are part of the same series.  Is there a way around this or a recommendation for using a separate series for each data item?
Thanks.

Hi Josh,

Currently RangeBar Chart type does not support DateTime as High/Low values type. Do you need to have a Gantt Chart in SL? If this is the case - this will be done soon with our ScheduleView control so stay tuned.

Thanks, Evgenia.
Yes, I am basically looking for a very simple Gantt chart to show start/end durations for each item in the series.
Will there be a simpler version of the ScheduleView control to do this or do I need to load the entire scheduler control to display a gantt chart?

Hello Josh,

There will be a simple version called GanttView but unfortunately I can not give you a definite timeframe for releasing it. Let us know if there is something else we can help you with.

Kind regards,
