For this i retrieved the data and put in a List.
PieDataList
PieResult = new PieDataList();
while (reader.Read())
{
PieResult.Add(
new PieData {Naam = reader["Name"].ToString(),Percentage = Convert.ToInt32(reader["Value"])});
}
Later I make sure my data is shown in a Pie Chart.
SeriesMapping
sm = new SeriesMapping();
sm.ItemMappings.Add(
new ItemMapping("Percentage", DataPointMember.YValue));
sm.ItemMappings.Add(
new ItemMapping("Naam", DataPointMember.LegendLabel));
PieChart1.SeriesMappings.Add(sm);
PieChart1.DefaultSeriesDefinition =
new PieSeriesDefinition() { ShowItemLabels = false };
PieChart1.ItemsSource = e.Result;
How can I now change the color of one particular object in my list?
And is it possible to show the values of my objects (Percentage) in the chart?
Kind regards,
Gj

Currently there is no way of changing the color of a particular object (if by object you mean pie slice). In the Q1 2010 version, which is to be released in a couple of days, we did rework the RadChart styling to allow easy color customizations.
For the object values, please, review the Format Expressions help topic.
All the best,
