    The quick start guides you through the steps of adding a MultiAutoComplete control to your MVC web application and add data to it using model binding.

    Follow the steps given below to get started. In the MultiAutoComplete control below, we are using a list of countries as our datasource. If you type 'ind' in the input element, it provides you with a list of countries that include 'ind' string in their names.


    Create an MVC Application

    Create a new MVC application using the ComponentOne or VisualStudio templates. For more information about creating an MVC application, see Configuring your MVC Application topic.

    Add a MultiAutoComplete Control

    Steps to add a MultiAutoComplete control to the application, are as follows:

    Add a new Controller

    1. In the Solution Explorer, right click the folder Controllers.
    2. From the context menu, select Add | Controller. The Add Scaffold dialog appears.
    3. In the Add Scaffold dialog, follow these steps:
      1. Select the Empty MVC Controller template.
      2. Set name of the controller (For example: MultiAutoCompleteController).
      3. Click Add.
    4. Include the following references as shown below.
      Copy Code
      using <ApplicationName>.Models;
      using System;
      using System.Collections.Generic;
      using System.Linq;
      using System.Web;
      using System.Web.Mvc;        

    5. Replace the Index() method with the following method.
      Copy Code
      public ActionResult Index()
         return View(Models.Countries.GetCountries());
    Add a View for the Controller

    In the view, we create an instance of MultiAutoComplete control and bind it to a data source using .Bind property. We have also defined the maximum numbers of items that can be selected using the MaxSelectedItems property.
    1. From the Solution Explorer, expand the folder Controllers and double click the MultiAutoCompleteController.
    2. Place the cursor inside the method Index().
    3. Right click and select Add View. The Add View dialog appears.
    4. In the Add View dialog, verify that the View name is Index and View engine is Razor (CSHTML).
    5. Click Add to add a view for the controller, and then copy the following code and paste it inside Index.cshtml.
      Copy Code
      @model List<string>
              .highlight {
                  background-color: #ff0;
                  color: #000;
      <c1-multi-auto-complete css-match="highlight" max-selected-items="4" 
          selected-indexes="new List<int> { 1 }">
          <c1-items-source source-collection="@Model">
