public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        
        // Create and configure SfButton
        SfButton sfButton1 = new SfButton();
        sfButton1.Text = "Click Me";
        sfButton1.Font = new System.Drawing.Font("Segoe UI", 10F);
        sfButton1.Location = new System.Drawing.Point(50, 50);
        sfButton1.Size = new System.Drawing.Size(120, 40);
        
        // Add click event
        sfButton1.Click += SfButton1_Click;
        
        // Add to form
        this.Controls.Add(sfButton1);
    }
    
    private void SfButton1_Click(object sender, System.EventArgs e)
    {
        MessageBox.Show("Button clicked!");
    }
}

Common Patterns

Pattern 1: Button with Image and Text

sfButton1.Text = "Save";
sfButton1.Image = Image.FromFile(@"save-icon.png");
sfButton1.TextImageRelation = TextImageRelation.ImageBeforeText;
sfButton1.ImageSize = new Size(20, 20);

Pattern 2: Icon-Only Button

sfButton1.Text = "";  // Empty text
sfButton1.Image = Image.FromFile(@"icon.png");
sfButton1.ImageSize = new Size(24, 24);
sfButton1.Style.BackColor = Color.White;
sfButton1.Style.Border = null;

Pattern 3: Button with State-Based Colors

sfButton1.Style.BackColor = Color.LightBlue;
sfButton1.Style.ForeColor = Color.Black;
sfButton1.Style.HoverBackColor = Color.Blue;
sfButton1.Style.HoverForeColor = Color.White;
sfButton1.Style.PressedBackColor = Color.DarkBlue;
sfButton1.Style.PressedForeColor = Color.White;

Pattern 4: Auto-Sizing Button

sfButton1.Text = "Variable Length Content";
sfButton1.AutoSize = true;  // Auto-adjust to content
sfButton1.Font = new Font("Segoe UI", 11F);

Pattern 5: Themed Button

// In Program.cs Main():
SfSkinManager.LoadAssembly(typeof(Office2016Theme).Assembly);

// In form:
sfButton1.ThemeName = "Office2016Colorful";
