Hello!
Attached are two versions of the ''Expander'' sample that shows expandible/collapsible nodes in Essential Diagram. If you are running the evaluation version of Essential Studio, or a pre 3.2 release of Essential Diagram, please use the ''Expander_EvalVersion'' sample.
Sample Highlights:
1. The Expander sample implements a custom ''ExpanderSymbol'' symbol class that extends the Essential Diagram Syncfusion.Windows.Forms.Diagram.Symbol base type, and allows a symbol to host child nodes.
2. The child symbols or sub-nodes are shown/hidden by double-clicking the parent node. The expanded/collapsed state of the symbol is indicated using +/- entities drawn by the ExpanderSymbol.
3. The sample uses employee information sourced from an XML format Access database file to create an organization chart diagram.
4. A Diagram LayoutManager is used for laying out the diagram nodes.
Thanks,
