SfPicker: Customize Selected Item when using custom item view

[Juan Ignacio Rodríguez]

Is there any way to customize selected item when using custom view (or ItemTemplate)?

ItemTemtemplate and CustomViews are great but right now you loose the feature to have diferente color or aspect for the selected item. This is a big deal specially in android because selected item is indistinguishable from unselected ones.

Hi Juan Ignacio Rodríguez, 

  

Greetings from Syncfusion. 

  

We have validated your query and prepared a workaround sample based on your requirement to differentiate SelectedItemTextColor & UnSelectedItemTextColor when using with Custom view (Item Template). Please find the code snippet and sample 

  

Code Snippet [XAML]: 

<picker:SfPicker  x:Name="picker" 

                          ItemsSource="{Binding Colors}" 

                          HeaderText="Select a Color" 

                          UnSelectedItemTextColor="Gray" 

                          SelectedItemTextColor="Red" 

                          SelectionChanged="Picker_SelectionChanged" > 

                <picker:SfPicker.ItemTemplate> 

                    <DataTemplate> 

                        <StackLayout> 

                            <Label Text="{Binding Name}" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" TextColor="{Binding ColorValue}"/> 

                        </StackLayout> 

                    </DataTemplate> 

                </picker:SfPicker.ItemTemplate> 

            </picker:SfPicker>  

 

  

Code Snippet [C#]: 

 private void Picker_SelectionChanged(object sender, Syncfusion.SfPicker.XForms.SelectionChangedEventArgs e) 

        { 

            var picker = (sender as SfPicker); 

  

            if (e.NewValue != null) 

            { 

                (e.NewValue as PickerColor).ColorValue = picker.SelectedItemTextColor; 

            } 

            if (e.OldValue != null) 

            { 

                (e.OldValue as PickerColor).ColorValue = picker.UnSelectedItemTextColor; 

            } 

        }
