Getting nested properties dynamically

Getting nested properties dynamically

it should still fix some issue Neither is there such functionality available at entity level (there have been attempts to implement this [1], [2]), nor is this something that PHP would support out of the box.
Generally you would have to iterate over the properties. You can find something like that in the entity context for the form helper, see EntityContext::val() for some inspiration.
code :
// in CakePHP versions before 3.1.0 you'd have to convert
// the entity to an array first using $entity->toArray()
Hash::get($entity, 'dot.notated.path')

hope this fix your issue I'm still starting to learn c# and winforms, so the following may not be optimal but it does what you required.
Handled the labels with Dock=Top. Note that the labels are switched so that label1 is on top of label2, i.e., registering label1 last pushes down the already registered label2.
code :
using System;
using System.Drawing;
using System.Windows.Forms;

public class ThreePanel : Form {

  FlowLayoutPanel  leftFlow;
  FlowLayoutPanel  middleFlow;
  FlowLayoutPanel  rightFlow;

  public ThreePanel(){

    leftFlow = new FlowLayoutPanel() {
      BackColor = Color.Yellow

    middleFlow = new FlowLayoutPanel() {
      BackColor = Color.LightGreen

    rightFlow = new FlowLayoutPanel() {
      BackColor = Color.LightBlue


    this.Load += (s,e)=>Form1_Shown(s,e);
    this.Resize += (s,e)=>{ 
      int w=this.Width/3; 
      leftFlow.Location=new Point(0,0);
      middleFlow.Location=new Point(w,0);
      rightFlow.Location=new Point(2*w,0);

    this.Size = new Size(750,450);


  private void Form1_Shown(object sender, EventArgs e)
    Panel p = new Panel() {
      BorderStyle = BorderStyle.FixedSingle,
      Width = 200,
      Height = 100,
      BackColor = Color.Fuchsia,

    Label label1 = new Label() {
      BorderStyle = BorderStyle.FixedSingle,
      Text = "Hello",
      Dock = DockStyle.Top

    Label label2 = new Label() {
      BorderStyle = BorderStyle.FixedSingle,
      Text = "World!",
      Dock = DockStyle.Top


    // add to the center most FlowLayoutPanel on Form1

  public static void Main()
    Application.Run(new ThreePanel());

fixed the issue. Will look into that further Your form fields must be prefixed (with BankAccount. or PayPalAccount.) so that they can be automatically bound.
When you return your partial view from Ajax, withthe current model you're using, their names don't have a prefix.
code :
@Html.EditorFor(m => m.BankAccount.BankName)
public class BakAccountModel
   // make sure the property name is the same as in the Person view model
   public BankAccount { get; set; } 
How do I use knockout to bind nested foreach loops on dynamically added properties?

hop of those help? To bind against your structure, you would need to turn the objects into arrays. Given that you are using the mapping plugin, the easiest way would likely be to use a binding that translates an object with properties to an array of key/values.
Here is a sample binding:
code :
ko.bindingHandlers.objectForEach = {
    init: function(element, valueAccessor, allBindings, data, context) {
        var mapped = ko.computed({
            read: function() {
                var object = ko.unwrap(valueAccessor()),
                    result = [];

                ko.utils.objectForEach(object, function(key, value) {
                    var item = {
                        key: key,
                        value: value


                return result;
            disposeWhenNodeIsRemoved: element

        //apply the foreach bindings with the mapped values
        ko.applyBindingsToNode(element, { foreach: mapped }, context);

        return { controlsDescendantBindings: true };

it fixes the issue Okay... I honestly don't think I understood the logic behind that menu configuration, but based solely on your code I could make the following improvements:
code :
result.then(res => {

    _MEV2_GLOBAL.menu_array = _MEV2_GLOBAL.menu_array || {};
    const array = _MEV2_GLOBAL.menu_array;

    res.forEach(r => {
        array[r.menu_type] = array[r.menu_type] || {};
        array[r.menu_type][r.menu_group] = array[r.menu_type][r.menu_group] || {};
        array[r.menu_type][r.menu_group][r.menu_id] = array[r.menu_type][r.menu_group][r.menu_id] || { menu_id: r.menu_id, menu_text: r.menu_text };

it helps some times It's good that you've found a solution of your specific problem.
Here is a more general solution which handles different source and target types as soon as the primitive property names and types match (e.g. Entity -> Dto etc.), as well as multiple levels of nesting:
code :
public static Expression<Func<TSource, TTarget>> BuildSelector<TSource, TTarget>(string members) =>
    BuildSelector<TSource, TTarget>(members.Split(',').Select(m => m.Trim()));

public static Expression<Func<TSource, TTarget>> BuildSelector<TSource, TTarget>(IEnumerable<string> members)
    var parameter = Expression.Parameter(typeof(TSource), "e");
    var body = NewObject(typeof(TTarget), parameter, members.Select(m => m.Split('.')));
    return Expression.Lambda<Func<TSource, TTarget>>(body, parameter);

static Expression NewObject(Type targetType, Expression source, IEnumerable<string[]> memberPaths, int depth = 0)
    var bindings = new List<MemberBinding>();
    var target = Expression.Constant(null, targetType);
    foreach (var memberGroup in memberPaths.GroupBy(path => path[depth]))
        var memberName = memberGroup.Key;
        var targetMember = Expression.PropertyOrField(target, memberName);
        var sourceMember = Expression.PropertyOrField(source, memberName);
        var childMembers = memberGroup.Where(path => depth + 1 < path.Length);
        var targetValue = !childMembers.Any() ? sourceMember :
            NewObject(targetMember.Type, sourceMember, childMembers, depth + 1);
        bindings.Add(Expression.Bind(targetMember.Member, targetValue));
    return Expression.MemberInit(Expression.New(targetType), bindings);
var test = BuildSelector<Shipment, Shipment>(
    "Recipient.CityName, Sender.CityId, Sender.CityName, ParcelUniqueId");
