RadAutoComplete control has been replaced with RadAutoCompleteView and will be removed from the suite soon. You can read about the differences between both components and how to migrate to the new RadAutoCompleteView in the kb article here: Replace AutoComplete with AutoCompleteView

Data Binding

For all cases where the business items are not simple strings data-binding is necessary in order to correctly visualize information. The RadAutoComplete component supports data binding in the form of path properties.

• TextSearchPath (string): Gets or sets the name of the property the search function will be executed against.
• ImagePath (string): Gets or sets the name of the property holding a path to an image. This property is optional.

The TextSearchPath property is required in data-binding scenarios.

The RadAutoComplete component provides a default template for suggestion items that cannot be modified. You can use a custom template if you need to customize the suggestion items.

Example

Here is a simple view model that will be used as data source for the RadAutoComplete suggestions.

• C#

public class BusinessObject
{
    public BusinessObject(string name, string imageSource)
    {
        this.Name = name;
        this.ImageSource = imageSource;
    }

    public string Name { get; set; }

    public string ImageSource { get; set; }
}

public class ViewModel
{
    public ViewModel()
    {
        this.Source = new List<BusinessObject>()
        {
            new BusinessObject("Freda Curtis", "available32.png"),
            new BusinessObject("Jeffery Francis", "away32.png"),
            new BusinessObject("Eva Lawson", "available32.png"),
            new BusinessObject("Emmett Santos", "away32.png"),

            new BusinessObject("Jarvis Victorine", "away32.png"),
            new BusinessObject("Dane Gabor", "busy32.png")
        };
    }

    public List<BusinessObject> Source { get; set; }
}

Here is how to setup the RadAutoComplete:

• XAML

<telerikInput:RadAutoComplete x:Name="AutoComplete"
                              ImagePath="ImageSource"
                              ItemsSource="{Binding Source}"
                              TextSearchPath="Name"
                              Watermark="Search here...">
    <telerikInput:RadAutoComplete.SuggestionViewHeight>
        <OnPlatform x:TypeArguments="x:Double"
                    Android="200"
                    WinPhone="400"
                    iOS="400" />
    </telerikInput:RadAutoComplete.SuggestionViewHeight>
    <telerikInput:RadAutoComplete.BindingContext>
        <local:ViewModel />
    </telerikInput:RadAutoComplete.BindingContext>
</telerikInput:RadAutoComplete>

Where:

• XAML

xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input"
