How do I display the ValueMemberPath without using the Tooltip?

[Matthew Bailey]

Ultimately my ideal solution would be to show the ValueMemberPath in the Legend along with the Category name itself, but if that's not possible, then I would like to have a way to display the selected value (and hierarchical children below it if possible).

Can someone help me figure this out?

Hi Matthew, 

 

Greetings from Syncfusion.  You can show the ValueMemberPath in label using the SelectionChanged event. This event occurs whenever you select the segment and get the SelectedSegment details (ValueMemberPath) as argument. Please find the code snippet below, 

 

[XAML]: 

<sunburst:SfSunburstChart x:Name="sunburstChart" ItemsSource="{Binding DataSource}" 

                                  ValueMemberPath="EmployeesCount" SelectionChanged="SunburstChart_SelectionChanged"> 

</sunburst:SfSunburstChart> 

 

 

[C#] 

private void SunburstChart_SelectionChanged(object sender, Syncfusion.SfSunburstChart.XForms.SelectionChangedEventArgs e) 

        { 

            if (e.SelectedSegment != null) 

            { 

                stackLayout.IsVisible = true; 

 

                if (!e.IsSelected) 

                { 

                    stackLayout.IsVisible = false; 

                } 

 

                if (e.SelectedSegment.CurrentLevel == 0) 

                { 

                    countryLabel.Text = "Continent: " + e.SelectedSegment.Category; 

                    populationLabel.Text = "Employee Count: " + e.SelectedSegment.Value; 

                } 

                else if (e.SelectedSegment.CurrentLevel == 1) 

                { 

                    countryLabel.Text = "Category: " + e.SelectedSegment.Category; 

                    populationLabel.Text = "Employee Count: " + e.SelectedSegment.Value; 

                } 

                else if (e.SelectedSegment.CurrentLevel == 2) 

                { 

                    countryLabel.Text = "Designation: " + e.SelectedSegment.Category; 

                    populationLabel.Text = "Employee Count: " + e.SelectedSegment.Value; 

                } 

                else  

                { 

                    countryLabel.Text = "Platform: " + e.SelectedSegment.Category; 

                    populationLabel.Text = "Employee Count: " + e.SelectedSegment.Value; 

                } 

            } 

        }
