Hi Devi,
I have modified the project so as to be like mine and I was able to reproduce the issue.
I use XAML binding and guess the error depends from this.

Hi Filippo,

Thanks for you update.

We have analyzed your provided sample and the exception thrown due to wrongly defined the LabelStyle property in ChartDataMarker. To apply the label style for data marker, we have to use DataMarkerLabelStyle as shown in below code.

 

XAML: 

<chart:ChartDataMarker LabelContent="YValue"> 

                      <chart:ChartDataMarker.LabelStyle> 

                        <chart:DataMarkerLabelStyle LabelPosition="Auto"></chart:DataMarkerLabelStyle> 

                      </chart:ChartDataMarker.LabelStyle> 

                    </chart:ChartDataMarker> 

                </chart:ColumnSeries.DataMarker> 

 

  

Output :  

Please find the modified sample in below location.

Sample: LabelContent129904 

Please refer the below UG link for setting label style for ChartDataMarker.
