The IconTintColorBehavior is a behavior that allows you to tint an image.

Important

The .NET MAUI Community Toolkit Behaviors do not set the BindingContext of a behavior, because behaviors can be shared and applied to multiple controls through styles. For more information refer to .NET MAUI Behaviors

Syntax

XAML

Including the XAML namespace

In order to use the toolkit in XAML the following xmlns needs to be added into your page or view:

xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"

Therefore the following:

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.MyPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml">

</ContentPage>

Would be modified to include the xmlns as follows:

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.MyPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">

</ContentPage>

Using the IconTintColorBehavior

The IconTintColorBehavior can be used as follows in XAML:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
             x:Class="MyLittleApp.MainPage">
    
    <Image Source="shield.png">
        <Image.Behaviors>
            <toolkit:IconTintColorBehavior TintColor="Red" />
        </Image.Behaviors>
    </Image>

</ContentPage>

C#

The IconTintColorBehavior can be used as follows in C#:

class IconTintColorBehaviorPage : ContentPage
{
    public IconTintColorBehaviorPage()
    {
        var image = new Image();

        var behavior = new IconTintColorBehavior
        {
            TintColor = Color.Red
        };

        image.Behaviors.Add(behavior);

        Content = image;
    }
}

C# Markup

Our CommunityToolkit.Maui.Markup package provides a much more concise way to use this Behavior in C#.

using CommunityToolkit.Maui.Markup;

class IconTintColorBehaviorPage : ContentPage
{
    public IconTintColorBehaviorPage()
    {
        Content = new Image()
        .Behaviors(new IconTintColorBehavior
        {
            TintColor = Color.Red
        });                 
    }
}
