TL;DR: Learn to use the Syncfusion .NET MAUI CheckBox to enhance product searches in a shopping app. Filter results by criteria like size, color, brand, and price range. Follow these steps: create a .NET MAUI app, add the CheckBox, implement filtering logic, and test the app for efficient and precise product searches.
The Syncfusion .NET MAUI CheckBox is a simple yet powerful tool that allows users to filter their search results based on the specified criteria. Whether you are shopping for clothing, electronics, or home goods, CheckBox can help you find the perfect item by allowing you to specify attributes such as size, color, brand, price range, and more.
This article will explore how the .NET MAUI CheckBox revolutionizes the shopping experience by enabling users to refine their product searches with precision and efficiency.
There are several reasons for choosing the Syncfusion .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.
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"/>
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> 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 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 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> 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;
} Refer to the following output image.
