TreeGrid: setting data root has no effect

Question

I\'m trying to setup a TreeGrid, my data object looks like this:

{
    \"code\": \"success\",
    \"data\": {
        \"text\": \".\",
        \"children\":          


        

Answer 1

Since you have setup your reader with root: 'data' you have to replace 'children' with 'data' in your json:

{
    "code": "success",
    "data": {
        "text": ".",
        "data": [ // << not "children"
            {
