Hi, Can you tell me how to add child nodes on parent Node tap. listeners:{ nodeItemTap:function(me,list,index,target,record,e){ debugger; var parentId=record.raw.TreeId; if(!target._record._data.expanded && !record.hasChildNodes()) { $.ajax({ url:"/Home/getJsonData/"+"&parentId="+parentId, method:"GET", gridRecord:record, gridMe:me, gridList:list, gridTarget:target, gridRecord:record, gridEvent:e, success:function(data){ var childrens=Ext.JSON.decode(data); for(var index in childrens){ this.gridRecord.insertChild(index,this.gridRecord.createNode(childrens[index])); } }, error:function(data){ console.log(data); } } }); } }

Hi, this is discussed in the forum starting at: https://www.sencha.com/forum/showthread.php?259616-TouchTreeGrid-component/page6

Note the discussion in the forum about needed override to handle sorting issue.

The latest demo of it can be seen at below address (the example of which is included in the download): http://www.gomainerentals.com/Sencha/DynamicLoadEx2C/index.html

Hi, Can you tell me how to get selected record from TreeGrid. I tried to implement a grid using your example of tasks, but i am stuck wondering how to get selected record in javascript.

TouchTreeGrid.controller.ProjectController from Kitchen Sink has listener for itemtap event: (this is "Project #3" example from http://www.gomainerentals.com/Sencha/TTG_KitchenSink/index.html)

        "list#example2Clist": {
            itemtap: 'onExample2ClistTap'
        }

onExample2ClistTap() method has record as one of the parameters. This method also shows how you can process a specific cell tap for treegrids.
