Basic PropertyGrid Setup

<Window x:Class="PropertyGridSample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:syncfusion="http://schemas.syncfusion.com/wpf">
    <Grid>
        <syncfusion:PropertyGrid Name="propertyGrid1" 
                                 SelectedObject="{Binding SelectedEmployee}"
                                 Width="400" Height="500">
            <syncfusion:PropertyGrid.DataContext>
                <local:ViewModel/>
            </syncfusion:PropertyGrid.DataContext>
        </syncfusion:PropertyGrid>
    </Grid>
</Window>

// Employee class to be explored in PropertyGrid
public class Employee : INotifyPropertyChanged
{
    private string name;
    public string Name 
    { 
        get => name; 
        set { name = value; OnPropertyChanged(nameof(Name)); } 
    }
    
    [Display(Name = "Employee ID")]
    [Description("Unique identifier for the employee")]
    public string ID { get; set; }
    
    [Category("Personal Info")]
    [DisplayName("Date of Birth")]
    public DateTime DOB { get; set; }
    
    [Category("Personal Info")]
    [Range(18, 65)]
    public int Age { get; set; }
    
    [Browsable(false)] // Hide this property
    public string InternalCode { get; set; }
    
    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string propertyName) =>
        PropertyChanged?.Invoke(this,  PropertyChangedEventArgs(propertyName));
}


  
{
      SelectedEmployee { ; ; }
    
    
    {
        SelectedEmployee =  Employee
        {
            Name = ,
            Age = ,
            ID = ,
            DOB =  DateTime(, , )
        };
    }
}

Common Patterns

Pattern 1: Custom Editor for Email Property

// Custom Editor with email validation mask
public class EmailEditor : ITypeEditor
{
    SfMaskedEdit maskedEdit;
    
    public object Create(PropertyInfo propertyInfo)
    {
        maskedEdit = new SfMaskedEdit
        {
            MaskType = MaskType.RegEx,
            Mask = "[A-Za-z0-9._%-]+@[A-Za-z0-9]+.[A-Za-z]{2,3}"
        };
        return maskedEdit;
    }
    
    public void Attach(PropertyViewItem property, PropertyItem info)
    {
        var binding = new Binding("Value")
        {
            Mode = BindingMode.TwoWay,
            Source = info,
            ValidatesOnExceptions = true,
            ValidatesOnDataErrors = true
        };
        BindingOperations.SetBinding(maskedEdit, SfMaskedEdit.ValueProperty, binding);
    }
    
    public void Detach(PropertyViewItem property) { }
}

// Apply to property
public class Employee
{
    [Editor("EmailID", typeof(EmailEditor))]
    public string EmailID { get; set; }
}

Pattern 2: Grouping Properties by Category

public class Employee
{
    [Category("Basic Info")]
    public string Name { get; set; }
    
    [Category("Basic Info")]
    public string ID { get; set; }
    
    [Category("Contact Details")]
    public string Email { get; set; }
    
    [Category("Contact Details")]
    public string Phone { get; set; }
}

<syncfusion:PropertyGrid SelectedObject="{Binding Employee}"
                         EnableGrouping="True"/>

Pattern 3: Editing Collection Properties

public class Product
{
    public string ProductName { get; set; }
    
    // Collection property - automatically gets collection editor
    public ObservableCollection<Customer> Customers { get; set; }
    
    public Product()
    {
        Customers = new ObservableCollection<Customer>
        {
            new Customer { ID = 1, Name = "John" },
            new Customer { ID = 2, Name = "Jane" }
        };
    }
}

public class Customer
{
    public int ID { get; set; }
    public string Name { get; set; }
}

Pattern 4: Override Property Items at Runtime

private void PropertyGrid_AutoGeneratingPropertyGridItem(
    object sender, AutoGeneratingPropertyGridItemEventArgs e)
{
    // Hide specific properties
    if (e.DisplayName == "InternalCode")
    {
        e.Cancel = true;
    }
    
    // Make property readonly
    if (e.DisplayName == "ID")
    {
        e.ReadOnly = true;
    }
    
    // Change display name
    if (e.DisplayName == "DOB")
    {
        e.DisplayName = "Date of Birth";
    }
    
    // Change category
    if (e.DisplayName == "Age")
    {
        e.Category = "Personal Information";
    }
}

Pattern 5: Property Value Changed Notification

private void PropertyGrid_ValueChanged(object sender, ValueChangedEventArgs e)
{
    var changedProperty = e.Property;
    var oldValue = e.OldValue;
    var newValue = e.NewValue;
    
    // Log the change
    Console.WriteLine($"{changedProperty.Name} changed from {oldValue} to {newValue}");
    
    // React to specific property changes
    if (changedProperty.Name == "Age")
    {
        // Validate or update related properties
    }
}

Related Components

• PropertyGridItem - Individual property item representation
• CustomEditor - Custom value editor configuration
• CategoryEditor - Category-based property grouping
• Collection Editor - Built-in collection editing dialog

Best Practices

1. Use Attributes for Metadata

   • Apply [Category], [Description], [DisplayName] attributes to properties
   • Use [Browsable(false)] to hide properties instead of code-based filtering

2. Implement INotifyPropertyChanged

   • Ensure your data objects implement property change notification
   • Use ObservableCollection for collection properties

3. Custom Editors for Complex Types

   • Create custom editors for types that don't have suitable default editors
   • Consider user experience when designing custom editor UI

4. Performance with Large Objects

   • Use virtualization for objects with many properties
   • Consider lazy loading for nested properties
   • Filter unnecessary properties early

5. Validation

   • Use data annotations for validation ([Required], [Range], etc.)
   • Handle validation errors gracefully in custom editors

6. Accessibility

   • Ensure custom editors support keyboard navigation
   • Provide meaningful descriptions for screen readers
   • Test with high contrast themes

Troubleshooting

Properties Not Showing

• Verify [Browsable] attribute is not false
• Check if property is in HidePropertiesCollection
• Ensure property has public getter
• Verify AutoGenerateItems is true

Custom Editor Not Applied

• Check editor is properly registered in CustomEditorCollection
• Verify property name/type matches
• Ensure editor implements ITypeEditor correctly
• Check Create method returns valid control

Collection Editor Not Opening

• Verify collection type derives from IList
• Ensure collection property has setter
• Check collection type has parameterless constructor
• Verify CollectionEditorOpening event doesn't cancel

Performance Issues

• Enable virtualization for large property sets
• Reduce nested property depth
• Filter unnecessary properties
• Consider manual property definition instead of auto-generation
