Tooltip in xaml code

[scorp]

<chart:SeriesMapping>

                           <chart:SeriesMapping.SeriesDefinition>

                               <chart:BarSeriesDefinition  ShowItemToolTips="True" />

                           </chart:SeriesMapping.SeriesDefinition>                          

                           <chart:SeriesMapping.ItemMappings>

                               <chart:ItemMapping FieldName="A" DataPointMember="YValue" />

                               <chart:ItemMapping FieldName="B" DataPointMember="XCategory" />

                           </chart:SeriesMapping.ItemMappings>

                       </chart:SeriesMapping>

how do we add a tooltip to show data returned via Binding property on our charts from xaml code. For instance data returns columns A, B and C. A is bound to Y axis B is bound to X axis and C needs to be the tooltip on the bars.
Thanks.

Hi,

The Tooltips can be shown using  ItemMapping with DataPointMemeber = "Tooltip" and FieldName which specifies from where the data should be taken. The approach is the same as those used to bind XCategory and YValue using ItemMappings. Here is what I mean:

<telerikChart:RadChart x:Name="radChart1">
         <telerikChart:RadChart.SeriesMappings>
             <telerikCharting:SeriesMapping>
                 <telerikCharting:SeriesMapping.SeriesDefinition>
                     <telerikCharting:BarSeriesDefinition ShowItemLabels="True" ShowItemToolTips="True"/>
                 </telerikCharting:SeriesMapping.SeriesDefinition>
                 <telerik:SeriesMapping.ItemMappings>
                     <telerik:ItemMapping DataPointMember="YValue"
                                        FieldName="Value1" />
                     <telerik:ItemMapping DataPointMember="XCategory"
                                        FieldName="Name" />
                     <telerik:ItemMapping DataPointMember="Tooltip"
                                        FieldName="MyTooltip" />
                 </telerik:SeriesMapping.ItemMappings>
             </telerikCharting:SeriesMapping>
         </telerikChart:RadChart.SeriesMappings>
     </telerikChart:RadChart>

And here is the code-behind:

public partial class MainPage : UserControl
    {
        public class Company
        {
            public string Name { get; set; }
            public double Value1 { get; set; }
            public string MyTooltip { get; set; }

            public Company(string name, double value1, string myTooltip)
            {
                Name = name;
                Value1 = value1;
                MyTooltip = myTooltip;
            }
        }

        public MainPage()
        {
            InitializeComponent();
            List<Company> sampleData = new List<Company>();
            sampleData.Add(new Company("RadChart", 100, "My Tooltip 1 - Chart"));
            sampleData.Add(new Company("RadGauge", 600,"My Tooltip 2 - Gauge"));
            sampleData.Add(new Company("RadMap", 300, "My Tooltip 3 - Map"));

            radChart1.ItemsSource = sampleData;
            radChart1.DefaultView.ChartArea.AxisY.AutoRange = false;
            radChart1.DefaultView.ChartArea.AxisY.AddRange(0, 1200, 100);
        }
    }
