Hi,

Im using version 2010.1.309.1030 and I need to reverse the legend item order in a stacked bar chart. as I'm on an older version I don;t have access to the ReverseLegendItemsOrder property, so I'm attempting to do the following:

Chart.DataBound += new EventHandler<ChartDataBoundEventArgs>(Chart_DataBound);

void Chart_DataBound(object sender, ChartDataBoundEventArgs e)
{
 var items = new List<ChartLegendItem>(Chart.DefaultView.ChartLegend.ItemsSource.Cast<ChartLegendItem>());
 items.Reverse();
 Chart.DefaultView.ChartLegend.ItemsSource = items;
}

However this seems to override the automatic crreation of the legend items, so when I rebind the chart with different data (and a different legend) the legend remains the previous one.

Thanks

Hi Jonathan,

In order to use the auto generated items, you have to work with the collection that is already set to the ChartLegend.ItemSource (instead of setting a new collection to it). Basically you need to change your last line with this: 
However when I tested this I noticed that if the code is executed in the RadChart.DataBound event handler, initially the chart legend items are not reversed. You can fix that by moving the code in the RadChart.LayoutUpdated event handler. The RadChart.DataBinding event is a appropriate moment to attach to the LayoutUpdated event. Here is an example:
