    <p>I want to implement drag and drop nodes in ExtJS TreeGrid. I am able to populate the TreeGrid but have no idea how is drag and drop handled in it. Here is my ExtJS code to populate the TreeGrid:</p> <pre><code>Ext.require([ 'Ext.data.*', 'Ext.grid.*', 'Ext.tree.*' ]); Ext.onReady(function () { Ext.define('Task', { extend: 'Ext.data.Model', fields: [ { name: 'task', type: 'string' }, { name: 'assignedto', type: 'string' } ] }); var store = Ext.create('Ext.data.TreeStore', { model: 'Task', proxy: { type: 'ajax', url: 'treegrid.json' }, folderSort: false }); var tree = Ext.create('Ext.tree.Panel', { title: 'Core Team Projects', width: 500, height: 300, renderTo: Ext.getBody(), collapsible: true, useArrows: true, rootVisible: false, store: store, multiSelect: true, singleExpand: true, columns: [{ xtype: 'treecolumn', text: 'Task', flex: 2, sortable: true, dataIndex: 'task' }, { text: 'Assigned To', flex: 1, dataIndex: 'assignedto', sortable: true }] }); </code></pre> <p>Following is the sample JSON data:</p> <pre><code>{"text":".","children": [ { task:'Task: R&amp;D', assignedto:'Reserved Team', iconCls:'task-folder', expanded: true, children:[{ task:'Grid', duration:1.25, assignedto:'Gopal Kanjoliya', iconCls:'task-folder', children:[{ task:'Create', duration:0.25, assignedto:'Gopal Kanjoliya', leaf:true, iconCls:'task' },{ task:'Read', duration:.4, assignedto:'Gopal Kanjoliya', leaf:true, iconCls:'task' }] }, { task:'Tree', duration:12, assignedto:'Gopal Kanjoliya', iconCls:'task-folder', expanded: true, children:[{ task:'Add Node', duration: 2.75, assignedto:'Gopal Kanjoliya', iconCls:'task-folder', children: [{ task: 'Delete', duration: 1.25, assignedto: 'Gopal Kanjoliya', iconCls: 'task', leaf: true }] },{ task:'Form', duration:2.75, assignedto:'Gopal Kanjoliya', leaf:true, iconCls:'task' }] }] },{ task:'Task: Implementation', duration:2, assignedto:'Development Team', iconCls:'task-folder', children:[{ task: 'Forms', duration: 0.75, assignedto: 'Gopal Kanjoliya', iconCls: 'task-folder', children: [{ task: 'Grids', duration: 0.25, assignedto: 'Gopal Kanjoliya', iconCls: 'task', leaf: true }] },{ task: 'Components', duration: 3.75, assignedto: 'Shyam Dhanotiya', iconCls: 'task-folder', children: [{ task: 'Panels', duration: 0.25, assignedto: 'Shyam Dhanotiya', iconCls: 'task', leaf: true }] },{ task: 'Test', duration: 0.5, assignedto: 'Snehil Chaturvedi', iconCls: 'task-folder', children: [{ task: 'Manual', duration: 0.25, assignedto: 'Snehil Chaturvedi', iconCls: 'task', leaf: true }] }] } ]} </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
