Xafari Explorer List Editor
Xafari platform provides a number of tools for convenient work with business objects that have tree-like hierarchical structure.
The following features are available for such objects:
- Displaying the hierarchical structure in a List View using special editors: ASPx Explorer List Editor, Win Hierarchy Node List Editor and ASPx Hierarchy Node List Editor. ASPx Explorer List Editor is a List Editor, which displays the data hierarchy in the form of a nested folders structure.
- Support for multiple hierarchies. A user can change the current hierarchy in the runtime.
To see the ASPx Explorer List Editor in action, refer to the figure below.
Explorer List Editor allows a user to focus on the work in a single node. Other nodes at this level are out of sight and do not distract the user from work.
ASPx Explorer List Editor supports of three deletion modes:
- Default – deleting the object and all references to the object; in so doing, all child elements of the object become root elements.
- Replacement – all child elements move up by one position in the hierarchy and end up in the parent's position when a node is deleted.
- Cascade – deleting the object and all its child objects.
One of the following three methods can be used to check whether child elements exist:
- Direct Database Count – makes request «Exists()» directly to the database.
- Collection Count - obtains a collection of child elements and compares the number of elements in the collection to zero.
- Default – Direct Database Count is used if no objects are edited, otherwise Collection Count is used.
