UniformItemsLayout

The UniformItemsLayout is a layout where all rows and columns have the same size.

Building an UniformItemsLayout

An UniformItemsLayout can be created in XAML or C#:

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 UniformItemsLayout

<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="MyProject.MyContentPage">

    <toolkit:UniformItemsLayout>
        <BoxView BackgroundColor="Blue" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Yellow" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Red" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Black" HeightRequest="25" WidthRequest="25"/>
    </toolkit:UniformItemsLayout>
    
</ContentPage>

C#

using CommunityToolkit.Maui.Views;

var page = new ContentPage
{
    Content = new UniformItemsLayout
    {
        Children = 
        {
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Blue },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Yellow },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Red },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Black }
        }
    }
};

Customizing an UniformItemsLayout

An UniformItemsLayout allows to limit the maximum number of columns and rows:

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="MyProject.MyContentPage">

    <toolkit:UniformItemsLayout MaxRows="1" MaxColumns="1">
        <BoxView BackgroundColor="Blue" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Yellow" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Red" HeightRequest="25" WidthRequest="25"/>
        <BoxView BackgroundColor="Black" HeightRequest="25" WidthRequest="25"/>
    </toolkit:UniformItemsLayout>
    
</ContentPage>

C#

using CommunityToolkit.Maui.Views;

var page = new ContentPage
{
    Content = new UniformItemsLayout
    {
        MaxRows = 1,
        MaxColumns = 1,
        Children = 
        {
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Blue },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Yellow },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Red },
            new BoxView { HeightRequest = 25, WidthRequest = 25, BackgroundColor = Colors.Black }
        }
    }
};
