I want to use an auto complete for selecting an item from an object. I'm using the item template and setting the value to a string. When selecting the name, which is 2 properties on the object it puts the id in the text box. How do I get the name to display while still using the id as the selected value?

 

 

01.@page "/test"
02. 
03.<h3>Test</h3>
04.<TelerikAutoComplete Data="@users" ValueField="@(nameof(TestUser.Id))"  @bind-Value="@userId" >
05.    <ItemTemplate Context="user">
06.        @user.FirstName @user.LastName
07.    </ItemTemplate>
08.</TelerikAutoComplete>
09.<button class="btn btn-primary edit-btn" @onclick="@Test">Test</button>
10. 
11.@code {
12. 
13.    private List<TestUser> users;
14.    private string userId;
15. 
16.    protected override Task OnInitializedAsync()
17.    {
18.        users = new List<TestUser>();
19.        users.Add(new TestUser { Id = 1, FirstName = "John", LastName = "Smith" });
20.        users.Add(new TestUser { Id = 2, FirstName = "Jane", LastName = "Doe" });
21.        users.Add(new TestUser { Id = 3, FirstName = "Olivia", LastName = "Williams" });
22.        users.Add(new TestUser { Id = 4, FirstName = "Noah", LastName = "Jones" });
23. 
24.        return base.OnInitializedAsync();
25.    }
26. 
27.    async Task Test()
28.    {
29.        Console.WriteLine(userId);
30.    }
31. 
32.    public class TestUser{
33. 
34.        public int Id { get; set; }
35.        public string LastName { get; set; }
36.        public string FirstName { get; set; }
37.    }
38.}

Hello Charles,

I'd recommend using the ComboBox for that, here's an example of using one field to show the text, and another to use as a value identifier: https://docs.telerik.com/blazor-ui/components/combobox/data-bind#bind-to-a-model

The autocomplete is a plain text input, think of it as a simple <input type=text> but where you (the application developer) control the autocomplete options instead of the browser.

Can you filter it as the user types? We may have 100+ users which is why I chose autocomplete.
