In our application, I will add a javascript file into Scripts folder. #Treeview angularjs codeStep-10: Add a javascript file, where we will write AangularJS code for creating an angular module and an angular controller. any workflow Packages Host and manage packages Security Find and fix vulnerabilities Codespaces Instant dev environments Copilot Write better code with Code review Manage code changes Issues Plan and track work Discussions Collaborate outside code Explore All. List = dc.MyFileStructures.OrderBy(a => a.FileName).ToList() By removing this indentation, you can create a toolbox like tree view, where tree hierarchy will appear as flat list. Using (MyDatabaseEntities dc = new MyDatabaseEntities()) Usually visual representation of tree hierarchy in Angular TreeView directive is created by shifting the child items to the right with small indentation relative to its parent. Step-9: Add an MVC action into HomeController for fetch data from the database and return as JSON result. import TreeView from 'devextreme/ui/treeview'. Var topLevels = list.Where(a => a.ParentID = list.OrderBy(b => b.ParentID).FirstOrDefault().ParentID) The TreeView UI component is a tree-like representation of textual data. Var childs = list.Where(a => a.ParentID = current.ID).ToList() This can be done using the dataSource property that is a member of the fields property. Use the searchMode property to specify whether nodes should contain (default), start with, or match the search string. TreeView can load data either from local data sources or remote data services. Enable the searchEnabled property to add the search bar. Public void GetTreeview(List list, MyFileStructure current, ref List returnList) The TreeView can display a search bar that allows users to search nodes. Recursion method for recursively get all child nodes So I am going to add the method in the HomeController. Now we need to write a recursion method for Recursively get all children's and make our JSON result as per example model, required for angularTreeview directive.
