Tree View

Load Data on Demand


In those special cases when the built-in Virtual Mode fails, you can gain full control over data loading in the createChildren function.This function is called each time a user expands the TreeView node that has not been expanded before. In the createChildren function, you get data from a server or other sources and then form the collection of child nodes from this data.

Copy to CodePen
$(function(){ $("#simple-treeview").dxTreeView({ createChildren: function(parent) { var parentId = parent ? : ""; return $.ajax({ url: "", dataType: "json", data: { parentId: parentId } }); }, rootValue: "", dataStructure: "plain", height: 500 }); });
