Node List: Linear Array
Documentation
This demo shows the Diagram widget's capability to load an external tree structure from a linear array.
The widget binds to a data object specified by the dataSource option. You should specify the keyExpr and parentKeyExpr options because of the data's linear structure. The Diagram uses information from the key fields to transform linear data into a tree.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
