Hello I want to make a "scope node" for a flow chart application, that will contain some other nodes(a node with some other nodes embedded). I want it to have expansion and collapsing capabilities.I want to know if your component has such capability and if there is some samples or articles in this regard. Thanks

Hi Behdad, Yes, it is possible to implement expanding/collapsing style nodes with Essential Diagram. I will post a sample that shows the feature within the next few hours. Prakash Surendra Syncfusion Inc.,

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, Prakash Syncfusion Inc., Expander_5678.zip Expander_EvalVersion_6468.zip
