Hi Manishkumar,

To be able to get the XValue and YValue of the right-clicked point you can use the following approach:
GetPosition method of the System.Windows.Point struct will give you the Physical X and Y coordinates of the mose pointer poition. You can easily get the Data standing behind these values by using our Axis.ConvertPhysicalUnitsToData method:
void ChartArea_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
      {
          Point myPoint = e.GetPosition((UIElement)sender);
          double x = RadChart1.DefaultView.ChartArea.AxisX.ConvertPhysicalUnitsToData(myPoint.X) + RadChart1.DefaultView.ChartArea.AxisX.MinValue;
          double y = RadChart1.DefaultView.ChartArea.AxisY.ConvertPhysicalUnitsToData(myPoint.Y) + RadChart1.DefaultView.ChartArea.AxisY.MinValue;
      }

Hi Manishkumar,

I believe that you haven't bound the XValue of the series. Binding it should solve your issue. For example:

<telerik:RadChart x:Name="RadChart1" ItemsSource="{Binding Data}">
            <telerik:RadChart.SeriesMappings>
                <telerik:SeriesMapping>
                    <telerik:SeriesMapping.SeriesDefinition>
                        <telerik:SplineRangeSeriesDefinition />
                    </telerik:SeriesMapping.SeriesDefinition>
                    <telerik:ItemMapping FieldName="Low" DataPointMember="Low" />
                    <telerik:ItemMapping FieldName="High" DataPointMember="High" />
                    <telerik:ItemMapping FieldName="Cat" DataPointMember="XCategory"/>
                </telerik:SeriesMapping>
            </telerik:RadChart.SeriesMappings>
        </telerik:RadChart>

For more information on Series Mappings, you may refer to our documentation.

I hope this helps.

All the best,
