Customizing Items Appearance

The content of items in CollectionEditor control can be customized by overriding the ToString method of the underlying data item's class or by using the ItemTemplate property of RadCollectionEditor.

Using ItemTemplate

The ItemTemplate property allows you to define a DataTemplate in order to replace the default appearance of the collection item visuals.

Setting the ItemTemplate

<telerikControls:RadCollectionEditor> 
    <telerikControls:RadCollectionEditor.ItemTemplate> 
        <DataTemplate> 
            <StackPanel Orientation="Horizontal"> 
                <Rectangle Width="16" Height="16" Fill="#FFD661"/> 
                <TextBlock Text="{Binding FirstName}" Margin="5 0 0 0" /> 
                <TextBlock Text="{Binding LastName}" Margin="3 0 0 0"/> 
            </StackPanel> 
        </DataTemplate> 
    </telerikControls:RadCollectionEditor.ItemTemplate> 
</telerikControls:RadCollectionEditor> 

Overriding ToString

Overriding the ToString method of the underlying data item's class allows you to easily replace the default content of the items.

The following example shows how to override ToString and populate the RadCollectionEditor with items.

Creating the data model

public class Employee 
{ 
        public string FirstName { get; set; } 
        public string LastName { get; set; } 
        public double Salary { get; set; } 
        public DateTime HireDate { get; set; } 
 
    public override string ToString() 
    { 
        return this.FirstName + " " + this.LastName; 
        } 
    } 

Setting up the data

this.collectionEditorPicker.Source = new BindableCollection<Employee>() 
{  
    new Employee() { FirstName = "John", LastName = "Doe", Salary = 10000, HireDate = DateTime.Today }, 
    new Employee() { FirstName = "John", LastName = "Doe Junior", Salary = 10000, HireDate = DateTime.Today }, 
    new Employee() { FirstName = "Jane", LastName = "Doe", Salary = 10000, HireDate = DateTime.Today }, 
};
