如何在 devextreme 中使用 ajax 发送选定的数据网格对象

Question

Friends, with devextreme datagrid, I cannot capture the selected objects in the asp.net core controller. The values appear as json in chrome web tools. But I can't fill the data with ajax on the controller side. Thanks for help

View:

 var datas=[];
    var gDeger;
    function selection_changed(selectedItems) {
        datas = selectedItems.selectedRowsData;
        $.map(datas,function (x) {
            gDeger = [{ Id: x.Id, Email: x.Email }];
        })
        console.log(datas); //The values appear as json in chrome web tools
        myfunction(datas);
    };

  function myfunction(gdeger) {            
        $.ajax({
            type: "post",
            dataType:"json",
            url: "/Admin/SendSablon",
            data: { eBultens: JSON.stringify(gdeger) },
            success: function (message) {
                console.log("true");
            },
            error: function () {
                console.log("error");
            }
        });
    }  

Controller:

    [HttpPost]
    public IActionResult SendSablon(List<EBulten> eBultens) // eBultens is null =(
    { 
        return Json(true);
    }

On the controller side, you should use this to get your values:

public IActionResult SendSablon(string values)
{
    dynamic keys = JsonConvert.DeserializeObject(values);
    var Id = keys.Id;
    var Email = keys.Email;
    // rest of code
}
