How to use URI images in .NET MAUI ListView?
You can display URI images in .NET MAUI ListView (SfListView) by loading image in ItemTemplate.
C#
Defining ContactImage property as string type in Model class.
public class Contacts : INotifyPropertyChanged
{
private string contactImage;
public string ContactImage
{
get { return this.contactImage; }
set
{
this.contactImage = value;
this.RaisedOnPropertyChanged("ContactImage");
}
}
}
C#
Set the image URI link to the ContactImage property when populating the items.
public class ContactsViewModel : INotifyPropertyChanged
{
public ObservableCollection<Contacts> ContactsInfo { get; set; }
public ContactsViewModel()
{
ContactsInfo = new ObservableCollection<Contacts>();
GenerateInfo();
}
public void GenerateInfo()
{
Random r = new Random();
for (int i = 0; i < 40; i++)
{
var contact = new Contacts(CustomerNames[i], r.Next(720, 799).ToString() + " - " + r.Next(3010, 3999).ToString());
contact.ContactImage = "https://upload.wikimedia.org/wikipedia/commons/thumb/1/12/User_icon_2.svg/220px-User_icon_2.svg.png"; //Your Url goes here
ContactsInfo.Add(contact);
}
}
}
XAML
Binding the ContactImage property to the Image.Source property as UriImageSource.
<ListView:SfListView x:Name="listView" ItemSize="60" ItemsSource="{Binding ContactsInfo}">
<ListView:SfListView.ItemTemplate >
<DataTemplate>
<Frame Padding="2" Margin="2" HasShadow="False" BorderColor="LightGray">
<Grid x:Name="grid" RowSpacing="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="70" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image HeightRequest="50" WidthRequest="50" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand" Aspect="AspectFit">
<Image.Source>
<UriImageSource Uri="{Binding ContactImage}" CacheValidity="1" CachingEnabled="true"/>
</Image.Source>
</Image>
<Grid Grid.Column="1" RowSpacing="1" Padding="10,0,0,0" VerticalOptions="Center">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Label Text="{Binding ContactName}" VerticalOptions="CenterAndExpand"/>
<Label Grid.Row="1" Text="{Binding ContactNumber}" VerticalOptions="StartAndExpand"/>
</Grid>
</Grid>
</Frame>
</DataTemplate>
</ListView:SfListView.ItemTemplate>
</ListView:SfListView>
