Unbound Mode

With this feature RadPropertyGrid enables its users to create their own nested property hierarchies, without the need to respect any of the actual parent/child or siblings relations.

AutogenerateBindingPaths

When non-auto-generated PropertyDefinitions are used, RadPropertyGrid relies on an internal “binding path generation” mechanism, as it is described in this article. This behavior can be modified by setting the AutogenerateBindingPaths property to "False". In this mode, it is mandatory to write the whole binding path, from the root (Item) level, to the respective nested property.

The following examples illustrate two possible hierarchies based on the following class definitions:

Example 1: Prepare sample objects

• C#
• VB.NET

public class Employee 
{ 
    public string Name { get; set; } 
    public DateTime HireDate { get; set; } 
    public Department Department { get; set; } 
} 
public class Department 
{ 
    public string Name { get; set; } 
    public int ID { get; set; } 
} 

Public Class Employee 
    Public Property Name() As String 
    Public Property HireDate() As Date 
    Public Property Department() As Department 
End Class 
Public Class Department 
    Public Property Name() As String 
    Public Property ID() As Integer 
End Class 

And the sample data:

Example 2: Prepare sample data

• C#
• VB.NET

InitializeComponent(); 
this.rpg.Item = new Employee() 
{ 
    Name = "Nancy Davolio", 
    HireDate = DateTime.Now, 
    Department = new Department() 
    { 
        ID = 1, 
        Name = "US Department" 
    } 
}; 

Public Sub New() 
    InitializeComponent() 
    Me.rpg.Item = New Employee() With { 
        .Name = "Nancy Davolio", 
        .HireDate = Date.Now, 
        .Department = New Department() With { 
            .ID = 1, 
            .Name = "US Department" 
        } 
    } 
End Sub 

Example 3: RadPropertyGrid UnboundMode first example

• XAML

<telerik:RadPropertyGrid x:Name="rpg"  
                         AutoGenerateBindingPaths="False"  
                         AutoGeneratePropertyDefinitions="False"  
                         NestedPropertiesVisibility="Visible"> 
    <telerik:RadPropertyGrid.PropertyDefinitions> 
        <telerik:PropertyDefinition DisplayName="Employee Info"> 
            <telerik:PropertyDefinition.NestedProperties> 
                <telerik:PropertyDefinition DisplayName="Name" Binding="{Binding Name}" /> 
                <telerik:PropertyDefinition DisplayName="HireDate" Binding="{Binding HireDate}" /> 
            </telerik:PropertyDefinition.NestedProperties> 
        </telerik:PropertyDefinition> 
        <telerik:PropertyDefinition DisplayName="Department Info"> 
            <telerik:PropertyDefinition.NestedProperties> 
                <telerik:PropertyDefinition DisplayName="Department Name" Binding="{Binding Department.Name}" /> 
                <telerik:PropertyDefinition DisplayName="Department ID" Binding="{Binding Department.ID}" /> 
            </telerik:PropertyDefinition.NestedProperties> 
        </telerik:PropertyDefinition> 
    </telerik:RadPropertyGrid.PropertyDefinitions> 
</telerik:RadPropertyGrid>

                         NestedPropertiesVisibility="Visible"> 
    <telerik:RadPropertyGrid.PropertyDefinitions> 
        <telerik:PropertyDefinition DisplayName="Name" Binding="{Binding Name}" > 
            <telerik:PropertyDefinition.NestedProperties> 
                <telerik:PropertyDefinition DisplayName="Department Name" Binding="{Binding Department.Name}">
