Binding ItemSource of SfListView to an observableCollection

Hi,

In the sample application attached, I want to bind TapView Products to TapModel Products.

I am not able to bind the list properly.

Could you please help.

Thanks

Hi Sonal, 

 

We suggest you create the bindable property as mentioned below, 

 

TapView 

public static readonly BindableProperty ProductListProperty = BindableProperty.Create( 

    nameof(ProductList), typeof(ObservableCollection<Product>), typeof(TapView), null, 

    BindingMode.Default, null, (bindable, oldValue, newValue) => 

    { 

        ((TapView)bindable).ItemsSource = (ObservableCollection<Product>)newValue; 

    }); 

 

public ObservableCollection<Product> ProductList 

{ 

    get { return (ObservableCollection<Product>)GetValue(ProductListProperty); } 

    set { SetValue(ProductListProperty, value); } 

} 

 

You can also refer to the following documentation to create bindable property in Xamarin.Forms, 

https://docs.microsoft.com/en-us/xamarin/xamarin-forms/xaml/bindable-properties#create-accessors 

 

Also, you need to create the property as the type of the model collection (i.e., ObservableCollection<Products>), or else binding error will be thrown.  

 

We have modified the sample to achieve your requirement and attached in the following link,

Please let us know if you need further assistance.
