Bind Form with combobox to Grid

Hello!

I try to bind my form with combo element to grid:

grid.setColumnIds('product_name,serial,amount');
grid.setStyle("text-align: center; padding-left: 0px;", "", "", "");
grid.setInitWidths('*,150,150');
grid.setColSorting('str,str,int');
grid.setColTypes("ro,ed,ed");
grid.enableAutoWidth(true);
grid.setFiltrationLevel(-1);
grid.setColValidators(",,ValidInteger");
grid.enableAccessKeyMap(true);
grid.init();


let formdata = [
    {
        type: "block", width: "auto", blockOffset: 0, list: [
            {type: "settings", position: "label-left", labelWidth: 80, inputWidth: 130},
            {
                type: "combo",
                label: "Product Name",
                labelAlign: "right",
                labelWidth: "150",
                name: "product_name",
                inputWidth: "380",
                connector: "index.php?r=docs/additemsdata2",
            },
            {
                type: "input",
                label: "Serial",
                value: "",
                labelAlign: "right",
                labelWidth: "150",
                name: "serial",
                inputWidth: "200",
                disabled: true
            },
            {type: "newcolumn"},
            { type: "input", label: "Amount", labelAlign: "right", labelWidth: "150", name: "amount", disabled: true },
            {type: "block", width: "350", offsetTop: "50", offsetLeft: "200", list: [
                    {type: "button", value: "Отменить", name: "cancelButtonAddForm"},
                    {type: "newcolumn"},
                    {type: "button", value: "Добавить", offsetLeft: 20, name: "addButtonAddForm"}
                ]
            }
        ]
    },
];

bindForm = wnd.attachForm(formdata);

bindForm.bind(grid);

bindForm.attachEvent(“onButtonClick”, function(name){
switch (name) {
case “addButtonAddForm”: bindForm.save(); break;
}
});

But Grid gets combo’s id to the product_name column. And I need that Grid gets a value of form’s combo. Would you help me what I need to do?

This is the expected behavior. UNfortunately it is not available to send the label of the combo instead of its’ id.
You may try to use the similar combo in your grid, so this “id” will be transformed to the “label” in your grid automatically.
