The following code example demonstrates handling the LinkClicked event by starting the Web browser for hyperlinks, and displaying a MessageBox for other links.
using System; using System.Drawing; using System.Windows.Forms; public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.LinkLabel linkLabel1; [STAThread] static void Main() { Application.Run(new Form1()); } public Form1() { // Create the LinkLabel. this.linkLabel1 = new System.Windows.Forms.LinkLabel(); // Configure the LinkLabel's size and location. Specify that the // size should be automatically determined by the content. this.linkLabel1.Location = new System.Drawing.Point(34, 56); this.linkLabel1.Size = new System.Drawing.Size(224, 16); this.linkLabel1.AutoSize = true; // Configure the appearance. // Set the DisabledLinkColor so that a disabled link will show up against the form's background. this.linkLabel1.DisabledLinkColor = System.Drawing.Color.Red; this.linkLabel1.VisitedLinkColor = System.Drawing.Color.Blue; this.linkLabel1.LinkBehavior = System.Windows.Forms.LinkBehavior.HoverUnderline; this.linkLabel1.LinkColor = System.Drawing.Color.Navy; this.linkLabel1.TabIndex = 0; this.linkLabel1.TabStop = true; // Add an event handler to do something when the links are clicked. this.linkLabel1.LinkClicked += new System.Windows.Forms.LinkLabelLinkClickedEventHandler(this.linkLabel1_LinkClicked); // Identify what the first Link is. this.linkLabel1.LinkArea = new System.Windows.Forms.LinkArea(0, 8); // Identify that the first link is visited already. this.linkLabel1.Links[0].Visited = true; // Set the Text property to a string. this.linkLabel1.Text = "Register Online. Visit Microsoft. Visit MSN."; // Create new links using the Add method of the LinkCollection class. // Underline the appropriate words in the LinkLabel's Text property. // The words 'Register', 'Microsoft', and 'MSN' will // all be underlined and behave as hyperlinks. // First check that the Text property is long enough to accommodate // the desired hyperlinked areas.
