WebBrowser.NewWindow Event


Occurs before a new browser window is opened.

 event System::ComponentModel::CancelEventHandler ^ NewWindow;
public event System.ComponentModel.CancelEventHandler NewWindow;
public event System.ComponentModel.CancelEventHandler? NewWindow;
member this.NewWindow : System.ComponentModel.CancelEventHandler 
Public Custom Event NewWindow As CancelEventHandler 
Public Event NewWindow As CancelEventHandler 

Event Type


The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the NewWindow event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type WebBrowser named WebBrowser1. Then ensure that the event handler is associated with the NewWindow event.

private void WebBrowser1_NewWindow(Object sender, CancelEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
MessageBox.Show(messageBoxCS.ToString(), "NewWindow Event" );
Private Sub WebBrowser1_NewWindow(sender as Object, e as CancelEventArgs) _ 
     Handles WebBrowser1.NewWindow

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
    MessageBox.Show(messageBoxVB.ToString(),"NewWindow Event")

End Sub


The WebBrowser control opens a separate browser window when the appropriate overload of the Navigate method is called or when the user clicks the Open in New Window option of the browser shortcut menu when the mouse pointer hovers over a hyperlink. You can disable the shortcut menu by setting the IsWebBrowserContextMenuEnabled property to false.

The NewWindow event occurs before the new browser window is opened. You can handle this event, for example, to prevent the window from opening when certain conditions have not been met.
