**Example 2: Dynamic Container Styling Based on Checkbox State**

```csharp
using SiticoneNetFrameworkUI;
using System.Drawing;
using System.Windows.Forms;

public class DynamicContainerStyleForm : Form
{
    private SiticoneCheckBox dynamicCheckBox;

    public DynamicContainerStyleForm()
    {
        InitializeComponent();
    }

    private void InitializeComponent()
    {
        this.dynamicCheckBox = new SiticoneCheckBox();
        this.SuspendLayout();

        // 
        // dynamicCheckBox
        // 
        this.dynamicCheckBox.Style = CheckBoxStyle.Minimal;
        this.dynamicCheckBox.IsContained = true;
        this.dynamicCheckBox.ContainerPadding = 8;
        this.dynamicCheckBox.ContainerBackColor = Color.White;
        this.dynamicCheckBox.ContainerBorderColor = Color.Gray;
        this.dynamicCheckBox.ContainerBorderWidth = 1;
        this.dynamicCheckBox.ContainerTopLeftRadius = 10;
        this.dynamicCheckBox.ContainerTopRightRadius = 10;
        this.dynamicCheckBox.ContainerBottomLeftRadius = 10;
        this.dynamicCheckBox.ContainerBottomRightRadius = 10;
        this.dynamicCheckBox.Text = "Agree to Terms";
        this.dynamicCheckBox.Location = new Point(50, 50);
        this.dynamicCheckBox.Size = new Size(180, 35);
        this.dynamicCheckBox.CheckStateChanged += DynamicCheckBox_CheckStateChanged;

        // 
        // DynamicContainerStyleForm
        // 
        this.ClientSize = new Size(300, 200);
        this.Controls.Add(this.dynamicCheckBox);
        this.Text = "SiticoneCheckBox - Dynamic Container Styling";
        this.ResumeLayout(false);
    }

    private void DynamicCheckBox_CheckStateChanged(object sender, CheckStateEventArgs e)
    {
        if (e.State == CheckState.Checked)
        {
            dynamicCheckBox.ContainerBackColor = Color.LightGreen;
            dynamicCheckBox.ContainerBorderColor = Color.Green;
        }
        else if (e.State == CheckState.Unchecked)
        {
            dynamicCheckBox.ContainerBackColor = Color.White;
            dynamicCheckBox.ContainerBorderColor = Color.Gray;
        }
        else if (e.State == CheckState.Indeterminate)
        {
            dynamicCheckBox.ContainerBackColor = Color.LightYellow;
            dynamicCheckBox.ContainerBorderColor = Color.Goldenrod;
        }
    }
}
```

**Explanation:**

* The checkbox is contained within a styled container with initial properties set for padding, background color, border color, and corner radii.
* An event handler `DynamicCheckBox_CheckStateChanged` is attached to respond to state changes.
* Depending on the checkbox's state (`Unchecked`, `Checked`, `Indeterminate`), the container's background and border colors are dynamically updated to reflect the current state, providing clear visual feedback.
