Example

This example demonstrates how to visualize flat data using the SunburstControl.

Create a SunburstFlatDataAdapter object and assign it to the SunburstControl.DataAdapter property to provide flat data to the Sunburst. Then, specify the adapter’s SunburstFlatDataAdapter.DataSource, SunburstFlatDataAdapter.LabelDataMember and SunburstFlatDataAdapter.ValueDataMember to define data source members that should be used to generate sunburst items. Add data members to the SunburstFlatDataAdapter.GroupDataMembers collection to specify how to group the sunburst’s items.

C#

private void OnLoad(object sender, EventArgs e) {
    SunburstFlatDataAdapter dataAdapter = new SunburstFlatDataAdapter();            
    dataAdapter.ValueDataMember = "Annual";
    dataAdapter.LabelDataMember = "Product";
    dataAdapter.GroupDataMembers.AddRange(new string[] { "Category", "Country" });
    dataAdapter.DataSource = CreateProductInfos();
    sunburstControl.DataAdapter = dataAdapter;
}

VB.NET

Class SurroundingClass
    Private Sub OnLoad(ByVal sender As Object, ByVal e As EventArgs)
        Dim dataAdapter As SunburstFlatDataAdapter = New SunburstFlatDataAdapter()
        dataAdapter.ValueDataMember = "Annual" 
        dataAdapter.LabelDataMember = "Product" 
        dataAdapter.GroupDataMembers.AddRange(New String() {"Category", "Country"})
        dataAdapter.DataSource = CreateProductInfos()
        sunburstControl.DataAdapter = dataAdapter
    End Sub 
End Class
