protected void btnSave_Click(object sender, EventArgs e) {
using (StreamWriter diagramData = File.CreateText(MapPath(diagramDataPath))) {
diagramData.WriteLine(Diagram.Export());
}
}
protected void btnLoad_Click(object sender, EventArgs e) {
Diagram.Import(File.ReadAllText(MapPath(diagramDataPath)));
}
Use the ASPxClientDiagram.Export and ASPxClientDiagram.Import methods to save and load the diagram data on the client side.
Note
The ASPxDiagram stores an opened diagram’s data in its own text format. Do not modify the data the Export method returns because a modified document can be loaded incorrectly.
