Refer to the following image.

Why choose Syncfusion .NET MAUI CheckBox?

There are several reasons for choosing the Syncfusion .NET MAUI CheckBox:

• Save time and effort: Instead of scrolling through pages of irrelevant products, the .NET MAUI CheckBox enables us to filter and narrow down our options to meet the specifications quickly. This saves you time and effort, allowing you to find what you need more efficiently.
• Compare products easily: The .NET MAUI CheckBox allows us to compare products side-by-side easily. For example, suppose you are shopping for shoes. In that case, you can use the CheckBox to narrow your options based on brand, size, color, and other specifications. This will allow you to compare different models more effectively.
• UI customization: The .NET MAUI CheckBox control’s shape, color, and text appearance can also be customized.

Tips for effective use of .NET MAUI Checkbox

• Prioritize your preferences: Determine the most important criteria for you and prioritize them accordingly.
• Experiment and explore: Do not be afraid to experiment with different combinations of CheckBox filters to see how they affect your search results.
• Stay flexible: Keep an open mind and be willing to adjust your search criteria as needed. Sometimes, the perfect product may not fit neatly into your initial preferences, so staying flexible can lead to exciting discoveries.

Steps to filter products using the .NET MAUI CheckBox

Follow these steps to create a project and filter products from the available items using the .NET MAUI CheckBox.

Here, we’ll demonstrate how to filter shoes from a pre-defined collection.

Step 1: Create a simple .NET MAUI CheckBox     

First, create a .NET MAUI app and integrate the .NET MAUI CheckBox by referring to the getting started documentation. The IsChecked property is set to True to indicate that filtering is enabled in the pre-defined collection.

<buttons:SfCheckBox Text="Campus" IsChecked="True"/>

Step 2: Create a simple .NET MAUI ListView

Now, integrate the .NET MAUI ListView control in the app by referring to its getting started documentation. This control renders data items using the views or custom templates. You can easily group, sort, and filter data using this control.

Refer to the following code example.

<listView:SfListView>
 <listView:SfListView.ItemTemplate>
  <DataTemplate>
      . . .
  </DataTemplate>
 </listView:SfListView.ItemTemplate>
</listView:SfListView>

Step 3: Populate items using data binding

Define the ProductInfo model class

Define a simple model class ProductInfo with fields like Brand, Description, Size, Color, and Image, as shown in the following code example.

public class ProductInfo
{
     public string Brand { get; set; }
     public string Description { get; set; }
     public string Size { get; set; }
     public Color Color { get; set; }
     public string Image { get; set; }

     public ProductInfo(string brand, string image, string size, Color color, string description)
     {
         Brand = brand;
         Description = description;
         Size = size;
         Color = color;
         Image = image;
     }
}

Create the ProductInfoViewModel class

Create a ViewModel class with the ProductInfo collection property initialized with the required number of data objects. Save it in a new class file named ProductInfoViewModel.cs, as shown in the following code example.

public class ProductInfoViewModel
{
    public ObservableCollection<ProductInfo> Products1 { get; set; }
    public GettingStartedViewModel()
    {
        Products1 = new ObservableCollection<Product>();
        string description1 = "Lightweight Sneakers for Men";
        string description2 = "Stylish Smart Sneakers for Men";
        Products1.Add(new Product("Campus", "brownshoe-01.png", "6   7   8", Colors.Brown, description1));
        Products1.Add(new Product("Campus ", "greenshoe-02.png", "6   7   8   9   10", Colors.Green, description2));
        Products1.Add(new Product("Campus ", "redshoe-03.png", "7   8   9   10 ", Colors.Red, description2));
        . . .
    }
}

Add CheckBoxes for product filtering

Add multiple CheckBoxes to filter products with the exact specifications. Then, bind the data collection to the ListView’s ItemsSource property.

<Grid>
 <Border>
  <Label Text="Filters" HorizontalOptions="Start"/>
 
  <StackLayout>
   <Label Text="Brand" />
   <Syncfusion:SfCheckBox HorizontalOptions="Start" Text="Campus" BindingContext="{x:StaticResource ViewModel}" IsChecked="{Binding BrandFilterChecked1}"/>
   <Syncfusion:SfCheckBox HorizontalOptions="Start" Text="Skechers"  BindingContext="{x:StaticResource ViewModel}" IsChecked="{Binding BrandFilterChecked2}"/>
   <Syncfusion:SfCheckBox HorizontalOptions="Start" Text="Red Tape"   BindingContext="{x:StaticResource ViewModel}" IsChecked="{Binding BrandFilterChecked3}"/>
   <Syncfusion:SfCheckBox HorizontalOptions="Start" Text="Roadster"  BindingContext="{x:StaticResource ViewModel}" IsChecked="{Binding BrandFilterChecked4}"/>
  </StackLayout>
  
   . . .
 </Border> 

 <Border>              
  <listView:SfListView BindingContext="{x:StaticResource ViewModel}" ItemsSource="{Binding Filtered}">
   <listView:SfListView.ItemTemplate>
    <DataTemplate>
        . . .
    </DataTemplate>
   </listView:SfListView.ItemTemplate>
  </listView:SfListView>
 </Border> 
</Grid>

Step 4: Filter products using .NET MAUI CheckBox

Now, filter the products based on the state of the CheckBox, as demonstrated in the following code example.

private ObservableCollection<Product> GetFilteredProducts()
{
    var filteredList = new ObservableCollection<ProductInfo>();

    if (brandFilterChecked1)
    {
        foreach (var product in Products1)
        {
            if (IsColorChecked(product) || IsColorUnfiltered())
                filteredList.Add(product);
        }
    }
    
    ...

    List<ProductInfo> products = new List<ProductInfo>();
    products = filteredList.OrderBy(x => Random.Shared.Next()).ToList<ProductInfo>();
    filteredList = this.GetCollection(products);

    return filteredList;
}
