RichTextBox.DetectUrls Property


Gets or sets a value indicating whether or not the RichTextBox will automatically format a Uniform Resource Locator (URL) when it is typed into the control.

 property bool DetectUrls { bool get(); void set(bool value); };
public bool DetectUrls { get; set; }
member this.DetectUrls : bool with get, set
Public Property DetectUrls As Boolean

Property Value

true if the RichTextBox will automatically format URLs that are typed into the control as a link; otherwise, false. The default is true.


The following code example contains an event handler for the LinkClicked event. The event handler processes link clicks within the document of a RichTextBox control and launches an instance of the default browser (using the Process.Start method), displaying the page for the link that was clicked. This example requires that the event handler has been connected to the LinkClicked event for a RichTextBox.

   void Link_Clicked( Object^ sender, System::Windows::Forms::LinkClickedEventArgs^ e )
      System::Diagnostics::Process::Start( e->LinkText );
private void Link_Clicked (object sender, System.Windows.Forms.LinkClickedEventArgs e)
Private Sub Link_Clicked(sender As Object, e As System.Windows.Forms.LinkClickedEventArgs)
End Sub


If this property is set to true, any text entered into the control that is determined by the RichTextBox to be a URL is automatically formatted as a link. You can create an event handler for the LinkClicked event to handle all links clicked in the control. The LinkClickedEventArgs that is provided to the event handler for the LinkClicked event provides data that enables you to determine which link was clicked in the control in order to process the link.
