Children doesn't appear

[eddi0815Participant]

Hallo Forum,
I don’t find the mistake why the children doesn’t appear in the view. I hope you can help me.
Thanks.

Data:

 var itemDetails = 
            [            
                {"Id": 0, "Key": "Id", "Value": item.id},
                {"Id": 1, "Key": "Name", "Value": item.name},
                {"Id": 3, "Key": "Description", "Value": item.description},
                {"Id": 4, "Key": "Datatype", "Value": item.datatype.id, children: [
                    {"Id": 5, "Key": "Basetype", "Value": "Test2"}
                ]},
                {"Id": 10, "Key": "Name", "Value": item.name},
                {"Id": 11, "Key": "Name", "Value": item.name},
                {"Id": 12, "Key": "Name", "Value": item.name},
                {"Id": 13, "Key": "Name", "Value": item.name}         
        ];

var source =
        {
            dataType: "json",
            dataFields: [
                { name: 'Id', type: 'number' },
                { name: 'Key', type: 'string' },
                { name: 'Value', type: 'string' }
            ],
            hierarchy:
            {
                root: 'children'
            },
            id: 'Id',
            localData: itemDetails
        };
        var dataAdapter = new $.jqx.dataAdapter(source);
        // create Tree Grid
        $("#treeGrid").jqxTreeGrid(
        {
            width: '100%',
            height: '100%',
            columnsResize: true,
            theme: 'arctic',
            source: dataAdapter,
            sortable: false,
            columns: [
                { text: 'Key', dataField: 'Key', width: '49%' },
                { text: 'Value', dataField: 'Value', width: '49%' }
            ]
        });

Hello eddi0815,

The reason the children do not appear is that you have not included the ‘children’ element in the source dataFields,
change it to:

               dataFields: [
                    { name: 'Id', type: 'number' },
                    { name: 'Key', type: 'string' },
                    { name: 'children', type: 'array' },
                    { name: 'Value', type: 'string' }
                ],

Best Regards,
Vladimir
