[Вадим]

 

there is a form.Added element DropDownTree. When you click on the confirmation, you need to get the value in the controller Category. Preferably in the format string []. Tell me how you can get values, even in a different format.Thank you. 

<form asp-action="CreateService" asp-controller="ServiceSubmit" asp-antiforgery="true" data-ajax="true" data-ajax-method="post" data-ajax-update="#result_login_register" >
                        <input name="IsValid" type="hidden" value="@ViewData.ModelState.IsValid.ToString()" />
                        <div class="form-group">
                            <label asp-for="Name">Краткое название</label>

Hello Vadim,

Thank you for the provided code snippet.

The selected items in the DropDownTree will be received through the submitted form in the "CreateService" Action Method as an array of strings when the data type of the "Value" property is string.

For example:

//Model
    public class OrderViewModel
    {
        public int OrderID { get; set; }
        public TreeItemViewModel Category { get; set; }
    }

    public class TreeItemViewModel
    {
        public string Id { get; set; }
        public string Value { get; set; }
        public string Text { get; set; }
    }

//View
        @(Html.Kendo().DropDownTree()
          .Name("Category")
          .DataTextField("Text")
          .DataValueField("Value")
          ...
        )

//Controller
[HttpPost]
public IActionResult CreateService(string[] Category)
{
  ...
}

If you have any further queries, don't hesitate to let me know.
