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";
