# Advanced PropertyGrid Example
|
||||
|
||||
This example demonstrates advanced features of the Avalonia PropertyGrid control with a comprehensive configuration editor.
|
||||
|
||||
## Features Demonstrated
|
||||
|
||||
### 1. **Nested Object Properties**
|
||||
- `DatabaseSettings` - Complex nested object with multiple properties
|
||||
- `NetworkSettings` - Another nested object showing hierarchical data
|
||||
- Both nested objects implement `INotifyPropertyChanged` for real-time updates
|
||||
|
||||
### 2. **Data Validation**
|
||||
- **Required fields**: `ServerName`, `Hostname`, `ConnectionString`
|
||||
- **Range validation**:
|
||||
- `MaxConnections` (1-1000)
|
||||
- `Port` (1-65535)
|
||||
- `CompressionLevel` (0-9)
|
||||
- **String length**: `ServerName` (3-50 characters)
|
||||
- Validation errors are displayed in the PropertyGrid
|
||||
|
||||
### 3. **Property Categories**
|
||||
Properties are organized into logical categories:
|
||||
- **Server Configuration** - Server name, connections, security
|
||||
- **Logging** - Logging settings and configuration
|
||||
- **Network** - Network and connectivity settings
|
||||
- **Database** - Database connection and performance
|
||||
- **Security** - Authentication and access control
|
||||
- **Performance** - Caching and optimization
|
||||
- **Appearance** - UI theme and visual settings
|
||||
- **Metadata** - Read-only system information
|
||||
|
||||
### 4. **Property Change Notifications**
|
||||
- Implements `INotifyPropertyChanged` interface
|
||||
- Real-time UI updates when properties change
|
||||
- Computed properties (e.g., `RequiresCertificate`) automatically update based on other properties
|
||||
- `LastModified` timestamp updates automatically
|
||||
|
||||
### 5. **Read-Only Properties**
|
||||
- `RequiresCertificate` - Computed based on `ConnectionType`
|
||||
- `ThemeColorName` - Computed based on `ThemeColor`
|
||||
- `CreatedDate`, `LastModified`, `ConfigurationId` - Metadata properties
|
||||
- `VIN` in the basic example - Demonstration of fixed values
|
||||
|
||||
### 6. **Various Data Types**
|
||||
- **Strings**: ServerName, ApiKey, ConnectionString
|
||||
- **Numbers**: Int (MaxConnections, Port), Decimal (Price in basic example)
|
||||
- **Enums**: ConnectionType, LogLevel, DatabaseProvider (with descriptions)
|
||||
- **Boolean**: EnableLogging, UseProxy, EnableRetry
|
||||
- **DateTime**: CreatedDate, LastModified
|
||||
- **TimeSpan**: Timeout
|
||||
- **Guid**: ConfigurationId
|
||||
- **Color**: ThemeColor (Avalonia.Media.Color)
|
||||
- **Collections**: List<string> for AllowedIPs
|
||||
|
||||
### 7. **Enum Descriptions**
|
||||
Enums include `[Description]` attributes for user-friendly display:
|
||||
```csharp
|
||||
public enum ConnectionType
|
||||
{
|
||||
[Description("Plain HTTP connection")]
|
||||
Http,
|
||||
|
||||
[Description("Secure HTTPS/SSL connection")]
|
||||
Ssl,
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
### 8. **Special Property Attributes**
|
||||
- `[PasswordPropertyText(true)]` - Hides API key text
|
||||
- `[EditorBrowsable(EditorBrowsableState.Advanced)]` - Groups advanced properties
|
||||
- `[Display]` - Custom names, descriptions, and ordering
|
||||
- `[Category]` - Logical grouping
|
||||
|
||||
### 9. **Property Ordering**
|
||||
Properties are ordered using the `Order` parameter in `[Display]` attribute:
|
||||
```csharp
|
||||
[Display(Name = "Server Name", Order = 1)]
|
||||
[Display(Name = "Max Connections", Order = 2)]
|
||||
```
|
||||
|
||||
### 10. **Search and Filter**
|
||||
The PropertyGrid includes built-in search functionality to quickly find properties across all categories.
|
||||

```
|
||||
|
||||
## Running the Example
|
||||
|
||||
1. Build the solution:
|
||||
```bash
|
||||
dotnet build Examples/AdvancedExample/AdvancedExample.csproj
|
||||
```
|
||||
|
||||
2. Run the application:
|
||||
```bash
|
||||
dotnet run --project Examples/AdvancedExample/AdvancedExample.csproj
|
||||
```
|
||||
|
||||
## Key Concepts
|
||||
|
||||
### INotifyPropertyChanged Implementation
|
||||
```csharp
|
||||
protected bool SetProperty<T>(ref T field, T value, [CallerMemberName] string? propertyName = null)
|
||||
{
|
||||
if (EqualityComparer<T>.Default.Equals(field, value))
|
||||
return false;
|
||||
|
||||
field = value;
|
||||
LastModified = DateTime.Now;
|
||||
OnPropertyChanged(propertyName);
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
### Computed Properties
|
||||
```csharp
|
||||
public bool RequiresCertificate => ConnectionType == ConnectionType.Ssl;
|
||||
```
|
||||
|
||||
### Nested Objects
|
||||
```csharp
|
||||
[Display(Name = "Database Settings", Description = "Database connection settings")]
|
||||
[Category("Database")]
|
||||
public DatabaseSettings DatabaseSettings { get; set; }
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Validation Rules
|
||||
|
||||
### String Validation
|
||||
```csharp
|
||||
[Required(ErrorMessage = "Server name is required")]
|
||||
[StringLength(50, MinimumLength = 3,
|
||||
ErrorMessage = "Server name must be between 3 and 50 characters")]
|
||||
public string ServerName { get; set; }
|
||||
```
|
||||
|
||||
### Numeric Range Validation
|
||||
```csharp
|
||||
[Range(1, 1000, ErrorMessage = "Max connections must be between 1 and 1000")]
|
||||
public int MaxConnections { get; set; }
|
||||
```
|
||||
|
||||
### Required Field Validation
|
||||
```csharp
|
||||
[Required]
|
||||
public string Hostname { get; set; }
|
||||
```
|
||||
|
||||
## Change Notification System
|
||||
|
||||
### Implementation Pattern
|
||||
```csharp
|
||||
private string _serverName = "Production-Server-01";
|
||||
|
||||
public string ServerName
|
||||
{
|
||||
get => _serverName;
|
||||
set => SetProperty(ref _serverName, value);
|
||||
}
|
||||
|
||||
protected bool SetProperty<T>(ref T field, T value,
|
||||
[CallerMemberName] string? propertyName = null)
|
||||
{
|
||||
if (EqualityComparer<T>.Default.Equals(field, value))
|
||||
return false;
|
||||
|
||||
field = value;
|
||||
LastModified = DateTime.Now; // Auto-update metadata
|
||||
OnPropertyChanged(propertyName);
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
### Cascading Updates
|
||||
When `ConnectionType` changes, `RequiresCertificate` automatically updates:
|
||||
```csharp
|
||||
public ConnectionType ConnectionType
|
||||
{
|
||||
get => _connectionType;
|
||||
set
|
||||
{
|
||||
if (SetProperty(ref _connectionType, value))
|
||||
{
|
||||
OnPropertyChanged(nameof(RequiresCertificate)); // Cascade
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
public bool RequiresCertificate => ConnectionType == ConnectionType.Ssl;
|
||||
```
|
||||
|
||||
## Computed Properties
|
||||
|
||||
Computed properties derive their value from other properties:
|
||||
|
||||
```csharp
|
||||
[Display(Name = "Requires Certificate", Order = 4)]
|
||||
[Category("Server Configuration")]
|
||||
[ReadOnly(true)]
|
||||
public bool RequiresCertificate => ConnectionType == ConnectionType.Ssl;
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Always in sync with source properties
|
||||
- No manual updates needed
|
||||
- Marked as read-only
|
||||
- Displayed in PropertyGrid but not editable
|
||||
|
||||
## Category Organization
|
||||
|
||||
Categories organize properties logically:
|
||||
|
||||
| Category | Purpose | Property Count |
|
||||
|----------|---------|----------------|
|
||||
| Server Configuration | Core server settings | 4 |
|
||||
| Logging | Logging and diagnostics | 3 |
|
||||
| Network | Network connectivity | 2 (+ nested) |
|
||||
| Database | Database connection | 1 (nested) |
|
||||
| Security | Authentication & access | 2 |
|
||||
| Performance | Optimization settings | 2 |
|
||||
| Metadata | System information | 3 |
|
||||
|
||||
## Property Ordering
|
||||
|
||||
Properties within categories are ordered using the `Order` attribute:
|
||||
|
||||
```csharp
|
||||
[Display(Order = 1)] // First in category
|
||||
[Display(Order = 2)] // Second in category
|
||||
[Display(Order = 3)] // Third in category
|
||||
```
|
||||
|
||||
## Special Attributes
|
||||
|
||||
### PasswordPropertyText
|
||||
Hides sensitive information:
|
||||
```csharp
|
||||
[PasswordPropertyText(true)]
|
||||
public string ApiKey { get; set; }
|
||||
```
|
||||
|
||||
### EditorBrowsable
|
||||
Groups advanced properties:
|
||||
```csharp
|
||||
[EditorBrowsable(EditorBrowsableState.Advanced)]
|
||||
public string LogFilePath { get; set; }
|
||||
```
|
||||
|
||||
### ReadOnly
|
||||
Prevents property editing:
|
||||
```csharp
|
||||
[ReadOnly(true)]
|
||||
public DateTime CreatedDate { get; set; }
|
||||
```
|
||||
|
||||
## Data Binding in XAML
|
||||
|
||||
### Setting DataContext
|
||||
```csharp
|
||||
// In MainWindow.axaml.cs
|
||||
public MainWindow()
|
||||
{
|
||||
InitializeComponent();
|
||||
DataContext = new AdvancedConfiguration();
|
||||
}
|
||||
```
|
||||
|
||||
### PropertyGrid Binding
|
||||
```xml
|
||||
<Window x:DataType="models:AdvancedConfiguration">
|
||||
<pg:PropertyGrid SelectedObject="{Binding}"
|
||||
ShowCategories="True"
|
||||
ShowDescriptions="True" />
|
||||
</Window>
|
||||
```
|
||||
|
||||
**Key Points:**
|
||||
- `x:DataType` enables compiled bindings (.NET 10 requirement)
|
||||
- `{Binding}` binds to the entire DataContext
|
||||
- `ShowCategories` enables category grouping
|
||||
- `ShowDescriptions` displays property descriptions
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Efficient Change Notifications
|
||||
```csharp
|
||||
protected bool SetProperty<T>(ref T field, T value, ...)
|
||||
{
|
||||
// Early exit if value hasn't changed
|
||||
if (EqualityComparer<T>.Default.Equals(field, value))
|
||||
return false;
|
||||
|
||||
// Only notify if changed
|
||||
field = value;
|
||||
OnPropertyChanged(propertyName);
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
### Lazy Initialization
|
||||
```csharp
|
||||
private DatabaseSettings _databaseSettings = new(); // Initialized once
|
||||
public DatabaseSettings DatabaseSettings => _databaseSettings;
|
||||
```
|
||||
|
||||
## Testing Scenarios
|
||||
|
||||
### Validation Testing
|
||||
1. Enter invalid server name (< 3 chars or > 50 chars)
|
||||
2. Set MaxConnections outside range (< 1 or > 1000)
|
||||
3. Leave required fields empty
|
||||
|
||||
### Change Notification Testing
|
||||
1. Change ConnectionType to/from Ssl
|
||||
2. Observe RequiresCertificate updates automatically
|
||||
3. Note LastModified timestamp changes
|
||||
|
||||
### Nested Object Testing
|
||||
1. Expand NetworkSettings
|
||||
2. Modify nested properties
|
||||
3. Verify changes propagate correctly
|
||||
|
||||
## Extension Points
|
||||
|
||||
### Adding New Properties
|
||||
1. Add private backing field
|
||||
2. Create public property with notifications
|
||||
3. Add appropriate attributes
|
||||
4. Assign to category
|
||||
|
||||
### Adding New Categories
|
||||
Simply use a new category name:
|
||||
```csharp
|
||||
[Category("New Category Name")]
|
||||
public string NewProperty { get; set; }
|
||||
```
|
||||
|
||||
### Custom Validation
|
||||
Implement `IDataErrorInfo` or `INotifyDataErrorInfo`:
|
||||
```csharp
|
||||
public class AdvancedConfiguration : INotifyPropertyChanged, IDataErrorInfo
|
||||
{
|
||||
public string Error => string.Empty;
|
||||
|
||||
public string this[string columnName]
|
||||
{
|
||||
get
|
||||
{
|
||||
// Return validation error for property
|
||||
return string.Empty;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### ✅ DO
|
||||
- Use INotifyPropertyChanged for all mutable properties
|
||||
- Add descriptions to all properties
|
||||
- Organize properties into logical categories
|
||||
- Validate user input
|
||||
- Use appropriate data types
|
||||
- Mark computed properties as read-only
|
||||
|
||||
### ❌ DON'T
|
||||
- Skip property change notifications
|
||||
- Mix unrelated properties in same category
|
||||
- Use generic category names like "Properties"
|
||||
- Forget validation on user input
|
||||
- Use string for structured data (use enums or objects)
|
||||
- Make computed properties editable
|
||||
|
||||
## Summary
|
||||
|
||||
The Advanced Example demonstrates:
|
||||
- ✅ 25+ properties across 7 categories
|
||||
- ✅ 2 levels of nested objects
|
||||
- ✅ Full INotifyPropertyChanged implementation
|
||||
- ✅ Comprehensive validation
|
||||
- ✅ Computed properties
|
||||
