The following code example demonstrates how to use a handler for the WebBrowser..::.Navigating event to cancel navigation when a Web page form has not been filled in. The WebBrowser..::.Document property is used to determine whether the form input field contains a value. This example requires that your form contains a WebBrowser control called webBrowser1.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) _
Handles Me.Load
webBrowser1.DocumentText = _
"<html><body>Please enter your name:<br/>" & _
"<input type='text' name='userName'/><br/>" & _
"<a href='http://www.microsoft.com'>continue</a>" & _
"</body></html>"
End Sub
Private Sub webBrowser1_Navigating( _
ByVal sender As Object, ByVal e As WebBrowserNavigatingEventArgs) _
Handles webBrowser1.Navigating
Dim document As System.Windows.Forms.HtmlDocument = _
webBrowser1.Document
If document IsNot Nothing And _
document.All("userName") IsNot Nothing And _
String.IsNullOrEmpty( _
document.All("userName").GetAttribute("value")) Then
e.Cancel = True
MsgBox("You must enter your name before you can navigate to " & _
e.Url.ToString())
End If
End Sub
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText =
"<html><body>Please enter your name:<br/>" +
"<input type='text' name='userName'/><br/>" +
"<a href='http://www.microsoft.com'>continue</a>" +
"</body></html>";
webBrowser1.Navigating +=
new WebBrowserNavigatingEventHandler(webBrowser1_Navigating);
}
private void webBrowser1_Navigating(object sender,
WebBrowserNavigatingEventArgs e)
{
System.Windows.Forms.HtmlDocument document =
this.webBrowser1.Document;
if (document != null && document.All["userName"] != null &&
String.IsNullOrEmpty(
document.All["userName"].GetAttribute("value")))
{
e.Cancel = true;
System.Windows.Forms.MessageBox.Show(
"You must enter your name before you can navigate to " +
e.Url.ToString());
