BorderStyle Enumeration

 

Specifies the border style for a control.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[ComVisibleAttribute(true)]
public enum BorderStyle

Member nameDescription
Fixed3D

A three-dimensional border.

FixedSingle

A single-line border.

None

No border.

Use the members of this enumeration to set the border style for controls that have a changeable border.

The following code example demonstrates how to use the BorderStyle enumeration and the TreeView.BorderStyle, TreeView.HideSelection and the TreeView.ShowRootLines properties. To run this example, paste the following code in a form and call the InitializeTreeView method in the form's constructor or Load method.


// Declare the TreeView control.
internal System.Windows.Forms.TreeView TreeView1;

// Initialize the TreeView to blend with the form, giving it the 
// same color as the form and no border.
private void InitializeTreeView()
{

	// Create a new TreeView control and set the location and size.
	this.TreeView1 = new System.Windows.Forms.TreeView();
	this.TreeView1.Location = new System.Drawing.Point(72, 48);
	this.TreeView1.Size = new System.Drawing.Size(200, 200);

	// Set the BorderStyle property to none, the BackColor property to  
	// the form's backcolor, and the Scrollable property to false.  
	// This allows the TreeView to blend in form.

	this.TreeView1.BorderStyle = BorderStyle.None;
	this.TreeView1.BackColor = this.BackColor;
	this.TreeView1.Scrollable = false;

	// Set the HideSelection property to false to keep the 
	// selection highlighted when the user leaves the control. 
	// This helps it blend with form.
	this.TreeView1.HideSelection = false;

	// Set the ShowRootLines and ShowLines properties to false to 
	// give the TreeView a list-like appearance.
	this.TreeView1.ShowRootLines = false;
	this.TreeView1.ShowLines = false;

	// Add the nodes.
	this.TreeView1.Nodes.AddRange(new TreeNode[]
		{new TreeNode("Features", 
			new TreeNode[]{
			new TreeNode("Full Color"), 
			new TreeNode("Project Wizards"), 
			new TreeNode("Visual C# and Visual Basic Support")}), 
			new TreeNode("System Requirements", 
			new TreeNode[]{
				new TreeNode("Pentium 133 MHz or faster processor "),
				new TreeNode("Windows 98 or later"), 
				new TreeNode("100 MB Disk space")})
		});

	// Set the tab index and add the TreeView to the form.
	this.TreeView1.TabIndex = 0;
	this.Controls.Add(this.TreeView1);
}
