how do you handle nested edit grids?

[bulivlad]

hi,
is there any way to get the parent row values in a nested grids setup? i ended up with 2 level nested grids in my form and i need to populate a field in a child grid based on a value picked in the parent grid. when retrieving data from the same row in the grid i can use row object but is there any parentRow or a similar way to get data from the parent?

the form setup looks something like

the form json below
{ "display": "form", "components": [ { "label": "Parent edit grid", "tableView": false, "rowDrafts": false, "key": "parentGrid", "type": "editgrid", "displayAsTable": false, "input": true, "components": [ { "label": "Parent select", "widget": "choicesjs", "tableView": true, "data": { "values": [ { "label": "yes", "value": "yes" }, { "label": "no", "value": "no" }, { "label": "idk", "value": "idk" } ] }, "key": "parentSelect", "type": "select", "input": true }, { "label": "Child data grid", "reorder": false, "addAnotherPosition": "bottom", "layoutFixed": false, "enableRowGroups": false, "initEmpty": false, "tableView": false, "defaultValue": [ {} ], "key": "childDataGrid", "type": "datagrid", "input": true, "components": [ { "label": "Child select", "widget": "choicesjs", "tableView": true, "key": "childSelect", "type": "select", "input": true } ] } ] }, { "type": "button", "label": "Submit", "key": "submit", "disableOnInvalid": true, "input": true, "tableView": false } ] }

You would probably need to use the "instance" property to get that.

// "instance" points to Child Select, "instance.parent" points to Child data grid, "instance.parent.data" points to the "row" data for the Child data grid.
instance.parent.data
