    string path

Name	Type	Description
path	String	Specifies the path to the file that contains the layout.

Remarks

Use the LoadFromFile method to load a diagram’s layout from an XML file. If this file does not exist, a System.IO.FileNotFoundException exception is raised. The resulting file does not contain information about a diagram source’s data - you should to specify the control’s DataSource property after the LoadFromFile method is called.

C#

private void Form1_Load(object sender, EventArgs e) {
    sankeyDiagramControl1.LoadFromFile("D:\\diagram1.xml");
    sankeyDiagramControl1.DataSource = GetSankeyItems();
}

VB.NET

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
    sankeyDiagramControl1.LoadFromFile("D:\diagram1.xml")
    sankeyDiagramControl1.DataSource = GetSankeyItems()
End Sub

To save a layout a file, call the ChartControl.SaveToFile method.
