Migrate from AutoComplete to AutoCompleteView

Control declaration:

  • AutoCompleteView
<telerikInput:RadAutoCompleteView x:Name="autoCompleteView" 
                                  Watermark="Search here..." />
  • AutoComplete
<telerikInput:RadAutoComplete x:Name="autoComplete" 
                              Watermark="Search here..." />
  • Same namespace
xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input"

SuggestionItemTemplate differences:

AutoCompleteView uses the Xamarin.Forms ListView for visualize the Suggestions. When the custom SuggestionItem Template is used you will need to add the ViewCell inside the DataTemplate. For example:

<telerikInput:RadAutoCompleteView.SuggestionItemTemplate>
    <DataTemplate>
       <ViewCell>
           <Grid>
               <Grid.ColumnDefinitions>
                   <ColumnDefinition Width="*" />
                   <ColumnDefinition Width="Auto" />
               </Grid.ColumnDefinitions>
               <Label Margin="5"
                      FontSize="24"
                      Text="{Binding Name}"
                      TextColor="Black"/>
                <Image Grid.Column="1"
                       Margin="5"
                       HeightRequest="20"
                       Source="{Binding ImageSource}"
                       WidthRequest="20"/>
             </Grid>
        </ViewCell>
    </DataTemplate>
</telerikInput:RadAutoCompleteView.SuggestionItemTemplate>
