Example
This example formats tooltip content for links and nodes.
To do this, handle the CustomizeLinkToolTip event and specify the CustomizeSankeyToolTipEventArgs.Title and CustomizeSankeyToolTipEventArgs.Content properties.
The e.Node.Tag, e.Link.Source.Tag, and e.Link.Target.Tag properties store values that are shown in the default tooltip titles. To obtain node and link weights, use the e.Node.TotalWeight and e.Link.TotalWeight properties.
private void Form1_Load(object sender, EventArgs e) {
sankeyDiagramControl1.ToolTipEnabled = DevExpress.Utils.DefaultBoolean.True;
sankeyDiagramControl1.ToolTipController = new DevExpress.Utils.ToolTipController {
ToolTipType = DevExpress.Utils.ToolTipType.Flyout,
AllowHtmlText = true
};
sankeyDiagramControl1.CustomizeLinkToolTip += OnCustomizeLinkToolTip;
}
private void OnCustomizeLinkToolTip(object sender, CustomizeSankeyLinkToolTipEventArgs e) {
e.Title = $"{e.Link.Source.Tag} → {e.Link.Target.Tag}";
e.Content = $"{e.Link.TotalWeight}";
}
