Styling Options

RadAutoCompleteView control provides the following Style properties for customizing its look:

  • Font Options(FontAttributes, FontFamily, FontSize): Define the font options to the text of the RadAutoCompleteView.
  • TextColor: Defines the textcolor of the component.
  • SuggestionItemTextColor: Defines the highlightcolor of the selection items.

Here is an example how to use the SuggestionItemTextColor property:

First, create the needed business objects, for example type Client with the following properties:

public class Client
{
    public Client(string name, string email, string imageSource)
    {
        this.Name = name;
        this.Email = email;
        this.ImageSource = imageSource;
    }
    public string Name { get; set; }
    public string Email { get; set; }
    public string ImageSource { get; set; }
}

Then create a ViewModel with a collection of Client objects:

public class ViewModel
{
    public ObservableCollection<Client> Source { get; set; }
    public ViewModel()
    {
        this.Source = new ObservableCollection<Client>()
        {
            new Client("Freda Curtis", "fcurtis@mail.com", "available32.png"),
            new Client("Jeffery Francis", "jfrancis@mail.com", "away32.png"),
            new Client("Eva Lawson", "elawson@mail.com", "available32.png"),
            new Client("Emmett Santos", "esantos@mail.com", "busy32.png"),
            new Client("Theresa Bryan", "tbryan@mail.com", "available32.png"),
            new Client("Jenny Fuller", "jfuller@mail.com", "busy32.png"),
            new Client("Terrell Norris", "tnorris@mail.com", "away32.png"),
            new Client("Eric Wheeler", "ewheeler@mail.com", "away32.png"),
            new Client("Nida Carty", "ncarty@mail.com", "away32.png"),
            new Client("Niki Samaniego", "nsamaniego@mail.com", "busy32.png")
        };
    }
}

Where the telerikInput namespace is the following:

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

Finally, use the following snippet to declare a RadAutoCompleteView in XAML with SuggestionItemTextColor property:

<telerikInput:RadAutoCompleteView x:Name="autoCompleteView1"
                                    ItemsSource="{Binding Source}"
                                    TextSearchPath="Name"
                                    Watermark="Search Here..."
                                    SuggestionItemTextColor="BlueViolet"
                                    SuggestionViewHeight="100"
                                    SuggestionViewBackgroundColor="#DBDBDB" />

Highlight Customization

In case a custom template is used, the user can achieve text highlighting inside the RadAutoCompleteView.SuggestionItemTemplate using SuggestionItemLabel and the following namespace:

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

The AutoCompleteView SuggestionItemLabel exposes the following properties:

  • HighlightTextColor
  • HighlightText
  • UnformattedText

Example

First, create the needed business objects, for example type Client with the following properties:

public class Client
{
    public Client(string name, string email, string imageSource)
    {
        this.Name = name;
        this.Email = email;
        this.ImageSource = imageSource;
    }
    public string Name { get; set; }
    public string Email { get; set; }
    public string ImageSource { get; set; }
}

Then create a ViewModel with a collection of Client objects:

public class ViewModel
{
    public ObservableCollection<Client> Source { get; set; }
    public ViewModel()
    {
        this.Source = new ObservableCollection<Client>()
        {
            new Client("Freda Curtis", "fcurtis@mail.com", "available32.png"),
            new Client("Jeffery Francis", "jfrancis@mail.com", "away32.png"),
            new Client("Eva Lawson", "elawson@mail.com", "available32.png"),
            new Client("Emmett Santos", "esantos@mail.com", "busy32.png"),
            new Client("Theresa Bryan", "tbryan@mail.com", "available32.png"),
            new Client("Jenny Fuller", "jfuller@mail.com", "busy32.png"),
            new Client("Terrell Norris", "tnorris@mail.com", "away32.png"),
            new Client("Eric Wheeler", "ewheeler@mail.com", "away32.png"),
            new Client("Nida Carty", "ncarty@mail.com", "away32.png"),
            new Client("Niki Samaniego", "nsamaniego@mail.com", "busy32.png")
        };
    }
}

Where the telerikInput namespace is the following:

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

and the autoCompleteView namespace is the following:

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

Finally, use the following snippet to declare a RadAutoCompleteView in XAML with SuggestionItemLabel property:

<telerikInput:RadAutoCompleteView x:Name="autoCompleteView2"
                                  ItemsSource="{Binding Source}"
                                  TextSearchPath="Name"
                                  Watermark="Search Here..."
                                  SuggestionViewHeight="100"
                                  SuggestionViewBackgroundColor="#DBDBDB">
    <telerikInput:RadAutoCompleteView.SuggestionItemTemplate>
        <DataTemplate>
            <ViewCell>
                <autoCompleteView:SuggestionItemLabel TextColor="Black"
                                                      HighlightTextColor="BlueViolet"
                                                      UnformattedText="{Binding Name}"
                                                      HighlightText="{Binding Source={x:Reference autoCompleteView2}, Path=Text}"/>
            </ViewCell>
        </DataTemplate>
    </telerikInput:RadAutoCompleteView.SuggestionItemTemplate>
</telerikInput:RadAutoCompleteView>

Here is the result:
