# How to bind JSON data to xamarin.Forms ListView (SfListView) ?

You can bind the data from JSON (JavaScript Object Notation) file in Xamarin.Forms SfListView using the ItemsSource property.

**XAML**

The JSON data can be bound to the SfListView ItemsSource property.

``` xml

    

                

                    

                        

                            

                                

                                

                            

                            

                                

                            

                            

                            

                        

                    

                

            

```

**C#**

Accessed the JSON file from local folder and StreamReader reads the data to return as a dynamic object.

``` c#

public ViewModel()

{

    var assembly = typeof(MainPage).GetTypeInfo().Assembly;

    Stream stream = assembly.GetManifestResourceStream( 

                    "ListViewXamarin.Data.Data.json");

    using (StreamReader sr = new StreamReader(stream))

    {

        var jsonText = sr.ReadToEnd();

        ItemsSource = JsonConvert.DeserializeObject(jsonText);

    }

}

```

**C#**

Dynamic object value converted by ExpandoObject to show the values.

``` c#

    public class DynamicToPathValueConverter : IValueConverter

    {

        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

        {

          if (value == null)

            return value;

          ExpandoObject busniessObject = JsonConvert.DeserializeObject(value.ToString());

          var jsonList = busniessObject.ToList();

          if (parameter.Equals("Value1"))       

            return jsonList[0].Value;

          if (parameter.Equals("Value2"))

            return jsonList[1].Value;

      return value;

   }

   public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)

   {

      throw new NotImplementedException();

   }

}

```
