    Quick Start
    In This Topic

    This quick start guides you through the steps of adding the AutoComplete control in your Blazor application, adding data to it and displaying the data in the control. In this example, we create a data source by creating a list of countries and bind the list to the control to display the names of countries in the control.

    Autocomplete binding

    Configure the Data Source

    In the Data folder, add a class, say Country, and add the following code.

    C#
    Copy Code
    public class Country
        {
            public override string ToString()
            {
                return Name;
            }
    
            public string Code { get; set; }
            public string Name { get; set; }
    
            public static List<Country> GetCountries()
            {
    
                var assembly = typeof(Country).GetTypeInfo().Assembly;
                var stream = assembly.GetManifestResourceStream("AutoComplete.Data.countries.json");
                var json = new System.IO.StreamReader(stream).ReadToEnd();
                var countries = JsonSerializer.Deserialize<Dictionary<string, string>>(json);
    
                var listContries = new List();
    
                foreach (var item in countries)
                {
                    listContries.Add(new Country() { Code = item.Key, Name = item.Value.ToString() });
                }
                return listContries.OrderBy(c => c.Name).ToList();
            }
         }
    }

    Bind AutoComplete to Data

    To bind AutoComplete to data, set the ItemsSource property and type of the type parameter T for C1AutoComplete component. Here, the ItemsSource property accepts the collection of items for the AutoComplete control.

    Replace the existing code in the Pages\Index.razor page with the following code.

    Razor
    Copy Code
    @using C1.Blazor.Input
    <C1AutoComplete ItemsSource="countries" T="Country" />
    
    @code
    {
        IEnumerable<Country> countries;
            
        protected override void OnInitialized()
        {
            countries = Country.GetCountries();
        }
    }
