Implementing Syncfusion Windows Forms BorderLayout

BorderLayout is a Windows Forms layout manager that allows you to arrange and layout child controls along the borders (North, South, East, West) to the center, similar to .NET framework's built-in docking support. Unlike automatic layout managers, BorderLayout gives you explicit control over positioning.

When to Use This Skill

• Layout with border regions: When you need to arrange controls along borders and a center area
• Top/bottom headers/footers: When you want a fixed header (North) and footer (South) with content in between
• Left/right sidebars: When you need a sidebar panel on the left or right with main content in the center
• Spacing control: When you need precise spacing between controls using HGap and VGap
• Designer or code-based layouts: Whether building UI in designer or programmatically in C#/VB.NET
• Alternative to docking: When you want a more structured approach than Windows Forms docking

Component Overview

Key Features:

• 5-position layout: North, South, East, West, Center positions for child controls
• Spacing configuration: Customize horizontal (HGap) and vertical (VGap) gaps between controls
• Designer support: Add BorderLayout and child controls via Visual Studio designer
• Code-based creation: Programmatically create and configure BorderLayout in C# or VB.NET
• Container control: Set any control (typically a Form) as the container for BorderLayout

Quick Start

Here's a minimal BorderLayout setup:

using Syncfusion.Windows.Forms.Tools;

// In your form
BorderLayout borderLayout1 = new BorderLayout();
this.borderLayout1.ContainerControl = this;

// Add controls
ButtonAdv topButton = new ButtonAdv() { Text = "Header", Dock = DockStyle.Top };
ButtonAdv leftButton = new ButtonAdv() { Text = "Sidebar", Dock = DockStyle.Left };
ButtonAdv centerButton = new ButtonAdv() { Text = "Content", Dock = DockStyle.Fill };

this.Controls.Add(topButton);
this.Controls.Add(leftButton);
this.Controls.Add(centerButton);

// Set positions
borderLayout1.SetPosition(topButton, BorderPosition.North);
borderLayout1.SetPosition(leftButton, BorderPosition.West);
borderLayout1.SetPosition(centerButton, BorderPosition.Center);

// Configure spacing
borderLayout1.HGap = 10;
borderLayout1.VGap = 10;

VB.NET Equivalent:

Imports Syncfusion.Windows.Forms.Tools

' In your form
Dim borderLayout1 As BorderLayout = New BorderLayout()
Me.borderLayout1.ContainerControl = Me

' Add controls
Dim topButton As ButtonAdv = New ButtonAdv() With {.Text = "Header", .Dock = DockStyle.Top}
Dim leftButton As ButtonAdv = New ButtonAdv() With {.Text = "Sidebar", .Dock = DockStyle.Left}
Dim centerButton As ButtonAdv = New ButtonAdv() With {.Text = "Content", .Dock = DockStyle.Fill}

Me.Controls.Add(topButton)
Me.Controls.Add(leftButton)
Me.Controls.Add(centerButton)

' Set positions
borderLayout1.SetPosition(topButton, BorderPosition.North)
borderLayout1.SetPosition(leftButton, BorderPosition.West)
borderLayout1.SetPosition(centerButton, BorderPosition.Center)

' Configure spacing
borderLayout1.HGap = 10
borderLayout1.VGap = 10

Common Patterns

Pattern 1: Header + Content + Footer

The most common layout with fixed header, scrollable content area, and fixed footer.

// Create panels for header, content, footer
Panel headerPanel = new Panel() { Height = 50 };
Panel contentPanel = new Panel();
Panel footerPanel = new Panel() { Height = 40 };

// Add to form
this.Controls.Add(headerPanel);
this.Controls.Add(contentPanel);
this.Controls.Add(footerPanel);

// Position with BorderLayout
borderLayout1.SetPosition(headerPanel, BorderPosition.North);
borderLayout1.SetPosition(footerPanel, BorderPosition.South);
borderLayout1.SetPosition(contentPanel, BorderPosition.Center);

Pattern 2: Sidebar + Content

Left sidebar with main content area.

// Create sidebar and content panels
Panel sidebarPanel = new Panel() { Width = 200 };
Panel contentPanel = new Panel();

this.Controls.Add(sidebarPanel);
this.Controls.Add(contentPanel);

// Position
borderLayout1.SetPosition(sidebarPanel, BorderPosition.West);
borderLayout1.SetPosition(contentPanel, BorderPosition.Center);

Pattern 3: Multi-Edge Layout

Controls on multiple edges with center content.

Panel top = new Panel() { Height = 40 };
Panel bottom = new Panel() { Height = 40 };
Panel left = new Panel() { Width = 150 };
Panel right = new Panel() { Width = 150 };
Panel center = new Panel();

this.Controls.Add(top);
this.Controls.Add(bottom);
this.Controls.Add(left);
this.Controls.Add(right);
this.Controls.Add(center);

borderLayout1.SetPosition(top, BorderPosition.North);
borderLayout1.SetPosition(bottom, BorderPosition.South);
borderLayout1.SetPosition(left, BorderPosition.West);
borderLayout1.SetPosition(right, BorderPosition.East);
borderLayout1.SetPosition(center, BorderPosition.Center);

Key Properties

Property	Type	Description
