    Hi phmaspnet,

    how to get data in to dropdownlist using .net core

    You can refer to the following example to populate DropDownList and get the selected data.

    TestDDL View:

    <div class="row">
    <div class="col-md-4">
        <form asp-action="UserSelection">
            <div class="form-group">
                <select asp-for="ItemIndex" asp-items="@Model.ItemList"></select>
            </div>
            <div class="form-group">
                <input type="submit" value="Submit" class="btn btn-default" />
            </div>
        </form>
    </div>
</div>

    TestDDL action:

    public IActionResult TestDDL()
{
    List<item> items = new List<item>() { new item() { Id = "1", Value = "Item1" }, new item() { Id = "2", Value = "Item2" }, new item() { Id = "3", Value = "Item3" } };

    TestViewModel model = new TestViewModel();

    model.ItemList = new SelectList(items.AsEnumerable(), "Id", "Value");

    return View(model);
}

    TestViewModel class:

    public class TestViewModel
{
    public string ItemIndex { get; set; }
    public SelectList ItemList { get; set; }
}

    item class:

    public class item
{
    public string Id { get; set; }
    public string Value { get; set; }
}

    UserSelection action:

    public string UserSelection(string ItemIndex)
{

    return $"The index of your selected option is {ItemIndex}";
}

    Test Result:

    wat is the use UIHint in mvc

    UIHintAttribute specifies the template or user control that Dynamic Data uses to display a data field, for detailed information, please check the link.

    With Regards,
