Step 1: Add the NuGet to the project and add the namespace as shown in the following code sample:
[XAML]
xmlns:buttons="clr-namespace:Syncfusion.XForms.Buttons;assembly=Syncfusion.Buttons.XForms"
[C#]
using Syncfusion.XForms.Buttons;
Step 2: Then initialize an empty SfChipGroup as shown in the following code:
[XAML]
<ContentPage.Content>
<Grid>
<buttons:SfChipGroup/>
</Grid>
</ContentPage.Content>
[C#]
public GettingStarted()
{
InitializeComponent();
Grid grid = new Grid();
grid.Children.Add(new SfChipGroup());
this.Content = grid;
}
To hide the selected chip selection indicator icon was achieved by adding the SfChip as the ItemTemplate of a ChipGroup. The default value of the SfChip's ShowSelectionIndicator property is false. Since, the selection indicator icon will be hidden by default while using the SfChip as an ItemTemplate.
In addition, we have to set the Transparent color to the BackgroundColor and BorderColor of the Chip in the ItemTemplate. It will take the BackgroundColor from the SelectedChipBackgroundColor and ChipBackgroundColor properties of ChipGroup. TextColor of the chips has been updated based on the IsChecked value with ChipTextColor and SelectedChipTextColor properties as per the following code example.
XAML:
…
<buttons:SfChipGroup
Type="Filter"
x:Name="chipGroup"
SelectedChipBackgroundColor="DarkGray"
ChipBackgroundColor="LightGray"
ChipTextColor="Black"
SelectedChipTextColor="White"
SelectionChanged="SessionListFilterOptions_SelectionChanged"
ItemsSource="{Binding Languages}"
ChipPadding="8,8,0,0"
SelectionIndicatorColor="White"
>
<buttons:SfChipGroup.ItemTemplate>
<DataTemplate>
<buttons:SfChip Text="{Binding Name}" InputTransparent="True"
BorderColor="Transparent"
BorderWidth="0"
TextColor="{Binding Source={x:Reference chipGroup},Path=ChipTextColor}"
BackgroundColor="Transparent">
<buttons:SfChip.Triggers>
<DataTrigger TargetType="buttons:SfChip" Binding="{Binding IsChecked}" Value="True" >
<Setter Property="TextColor" Value="{Binding Source= {x:Reference chipGroup}, Path=SelectedChipTextColor}"/>
</DataTrigger>
</buttons:SfChip.Triggers>
</buttons:SfChip>
</DataTemplate>
</buttons:SfChipGroup.ItemTemplate>
</buttons:SfChipGroup>
…
C#:
private void SessionListFilterOptions_SelectionChanged(object sender, Syncfusion.Buttons.XForms.SfChip.SelectionChangedEventArgs e)
{
if (e.AddedItem != null)
{
(e.AddedItem as Language).IsChecked = true;
}
if (e.RemovedItem != null)
{
(e.RemovedItem as Language).IsChecked = false;
}
}
To run this application, you need to first clone the How-to-remove-the-indicator-icon-from-Xamarin.Forms-SfChipGroup repository and then open it in Visual Studio 2022. Now, simply build and run your project to view the output.
If you are facing path too long exception when building this example project, close Visual Studio and rename the repository to short and build the project.
