# WPF Style & ResourceDictionary Patterns

Effectively managing Style and ResourceDictionary for consistent UI and maintainability.

## 1. Style Basic Structure

### 1.1 Explicit Style (With Key)

```xml
<Window.Resources>
    <!-- Explicit style: must reference by key to apply -->
    <Style x:Key="PrimaryButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="#2196F3"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Padding" Value="16,8"/>
        <Setter Property="FontWeight" Value="SemiBold"/>
    </Style>
</Window.Resources>

<Button Style="{StaticResource PrimaryButtonStyle}" Content="Primary"/>
```

### 1.2 Implicit Style (Without Key)

```xml
<Window.Resources>
    <!-- Implicit style: auto-applied to all controls of that type -->
    <Style TargetType="{x:Type Button}">
        <Setter Property="Margin" Value="5"/>
        <Setter Property="Cursor" Value="Hand"/>
    </Style>
</Window.Resources>

<!-- Style automatically applied -->
<Button Content="Auto Styled"/>
```

## 2. Style Inheritance (BasedOn)

### 2.1 Basic Inheritance

```xml
<!-- Base button style -->
<Style x:Key="BaseButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Padding" Value="12,6"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Cursor" Value="Hand"/>
</Style>

<!-- Primary button: inherits base style -->
<Style x:Key="PrimaryButtonStyle" TargetType="{x:Type Button}"
       BasedOn="{StaticResource BaseButtonStyle}">
    <Setter Property="Background" Value="#2196F3"/>
    <Setter Property="Foreground" Value="White"/>
</Style>

<!-- Secondary button: inherits base style -->
<Style x:Key="SecondaryButtonStyle" TargetType="{x:Type Button}"
       BasedOn="{StaticResource BaseButtonStyle}">
    <Setter Property="Background" Value="#E0E0E0"/>
    <Setter Property="Foreground" Value="#424242"/>
</Style>
```

### 2.2 Implicit Style Inheritance
