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

Create a Blazor App

In Visual Studio, select Create a new project from the Get Started pane.
In the Create a new project dialog, select Blazor App and click Next.
In the Configure your new project dialog, provide name of the project you want to create in the Project name field and location for the project in the Location field. Click Create.
In the Create a new Blazor app dialog, select Blazor Server App template and click Create. A new server-side Blazor app is created.
Note: Blazor Client-side app or WebAssembly app can be created using the Blazor WebAssembly App template. For details, check the Blazor WebAssembly topic in Blazor templates.

Configure References

In the Solution Explorer, right click Dependencies and select Manage NuGet Packages.
In NuGet Package Manager, select nuget.org as the Package source.
Search for C1.Blazor.Input package and click Install.
Navigate to the wwwroot, open index.html file.

Configure the Data Source

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

C#	コードのコピー
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(); } } }

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.

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