Property Value

Type	Description
IList	The collection of selected Sankey links and nodes.

Remarks

Add links and nodes to the SelectedItems collection to select them. When you use the SelectedItems property to change the Sankey element selection, the SankeyDiagramControl ignores whether the selection is enabled in the SelectionMode property.

The following example selects the France node and the related links:

C#

List<SankeyItem> data = new List<SankeyItem> {
    new SankeyItem { Source = "France", Target = "UK", Value = 53 },
    new SankeyItem { Source = "Australia", Target = "UK", Value = 72 },
    new SankeyItem { Source = "France", Target = "Canada", Value = 81 },
    new SankeyItem { Source = "China", Target = "Canada", Value = 96 },
    new SankeyItem { Source = "UK", Target = "France", Value = 61 },
    new SankeyItem { Source = "Canada", Target = "France", Value = 89 }
};
sankeyDiagramControl1.DataSource = data;
sankeyDiagramControl1.SourceDataMember = "Source";
sankeyDiagramControl1.TargetDataMember = "Target";
sankeyDiagramControl1.WeightDataMember = "Value";
sankeyDiagramControl1.Titles.Add(new SankeyTitle { Text = "Export/Import", Font = new Font("Tahoma", 14) });

sankeyDiagramControl1.SelectedItems.Add("France");
sankeyDiagramControl1.SelectedItems.Add(data[0]);
sankeyDiagramControl1.SelectedItems.Add(data[2]);
sankeyDiagramControl1.SelectedItems.Add(data[5]);

            .Source = "France",
            .Target = "UK",
            .Value = 53
        },
