Data Binding in .NET MAUI ComboBox
-
ItemsSource(IEnumerable): Defines the collection of the items that will populate the control with data. -
DisplayMemberPath(string): Defines the name of the property which will be visualized inside the dropdown list.
If DisplayMemberPath is not set the “ToString” implementation of the business object will be visualized. The DisplayMemberPath is a property that helps the developers to visualize an exact property from the business object they are bound to.
Binding to a complex object
Here is the ComboBox definition in XAML:
<telerik:RadComboBox ItemsSource="{Binding Items}"
DisplayMemberPath="Population"
AutomationId="boundComboBox"/>
In addition to this, you need to add the following namespace:
xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
public class City
{
public string Name { get; set; }
public int Population { get; set; }
}
and the ViewModel used:
public class ViewModel
{
public ViewModel()
{
this.Items = new ObservableCollection<City>
{
new City { Name = "Tokyo", Population = 13929286 },
new City { Name = "New York", Population = 8623000 },
new City { Name = "London", Population = 8908081 },
new City { Name = "Madrid", Population = 3223334 },
new City { Name = "Los Angeles", Population = 4000000},
new City { Name = "Paris", Population = 2141000 },
new City { Name = "Beijing", Population = 21540000 },
new City { Name = "Singapore", Population = 5612000 },
new City { Name = "New Delhi", Population = 18980000 },
new City { Name = "Bangkok", Population = 8305218 },
new City { Name = "Berlin", Population = 3748000 },
};
}
public ObservableCollection<City> Items { get; set; }
}
