I tried two method:
wb.Navigate(Url,true); When i use this webbrowser appear but WebBrowserDocumentCompleted event doesn't fire after page loaded.
wb.Navigate(Url); When i use this WebBrowserDocumentCompleted event is firing but browser doesn't appear on screen. How can i display external browser and fire WebBrowserDocumentCompleted event same time?
private void button1_Click(object sender, EventArgs e)
{
System.Windows.Forms.WebBrowser wb = new System.Windows.Forms.WebBrowser();
wb.DocumentCompleted += WebBrowserDocumentCompleted;
wb.Visible = true;
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate("http://www.google.com",true);
}
private void WebBrowserDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if ((sender as WebBrowser).ReadyState == System.Windows.Forms.WebBrowserReadyState.Complete)
{
// Do what ever you want to do here when page is completely loaded.
}
}

I have this form which has a System.Windows.Forms.WebBrowser controller in it. One of the html pages has some href in it like this
<a href="https://twitter.com/xxx" target="_blank">
<h3 style="margin-top:15%; text-align:center">xxx</h3>
</a>
I am catching the clicks in the
private void webBrowser1_NewWindow(object sender, CancelEventArgs e)
and opening the page as so
webBrowser1.Navigate(page);
Now this works and the page is shown inside the webBrowser1, but this also opens the external IE with the same page. Actually, the external IE opens first before the webBrowser1 shows the page.
So my question is: Why does the external IE opens and how can I stop this.
cheers,

Instead of opening a new page try to create custom onClick event
private bool bCancel = false;
private void webBrowser_DocumentCompleted(object sender,
WebBrowserDocumentCompletedEventArgs e)
{
int i;
for (i = 0; i < webBrowser.Document.Links.Count; i++)
{
webBrowser.Document.Links[i].Click += new
HtmlElementEventHandler(this.LinkClick);
}
}
private void LinkClick(object sender, System.EventArgs e)
{
bCancel = true;
MessageBox.Show("Link Was Clicked Navigation was Cancelled");
}
private void webBrowser_Navingating(object sender,
WebBrowserNavigatingEventArgs e )
{
if (bCancel == true)
{
e.Cancel=true;
bCancel = false;
}
}
I have two textboxes. I need to validate them before taking any other action.
private ErrorProvider _errorProviderEmail = new ErrorProvider();
private ErrorProvider _errorProviderPass = new ErrorProvider();
public FormLogin()
{
InitializeComponent();
textBoxEmail.Validating += TextBoxEmailValidating;
textBoxPass.Validating += TextBoxPassValidating;
textBoxEmail.Validated += TextBoxEmailValidated;
textBoxPass.Validated += TextBoxPassValidated;
textBoxEmail.Text = "";
textBoxPass.Text = "";
}
void TextBoxPassValidated(object sender, EventArgs e)
{
_errorProviderPass.SetError(textBoxPass, "");
}
void TextBoxEmailValidated(object sender, EventArgs e)
{
_errorProviderEmail.SetError(textBoxEmail, "");
}
void TextBoxPassValidating(object sender, System.ComponentModel.CancelEventArgs e)
{
if (!string.IsNullOrEmpty(textBoxPass.Text)) return;
e.Cancel = true;
_errorProviderPass.SetError(textBoxPass,"Password is required!");
}
void TextBoxEmailValidating(object sender, System.ComponentModel.CancelEventArgs e)
{
if (!string.IsNullOrEmpty(textBoxEmail.Text)) return;
e.Cancel = true;
_errorProviderEmail.SetError(textBoxEmail, "Email address is required!");
}
The problem is that only validating event for textBoxEmail is triggered, what could be wrong here, and why the validating event for textBoxPass never fires?
The individual TextBox controls only validate when they lose their focus.
Try calling the form's ValidateChildren() function to force each control to call their validation handlers:
private void button1_Click(object sender, EventArgs e) {
if (this.ValidateChildren()) {
this.Close();
}
}
Also, you only need one ErrrorProvider component.
The Validating event is raised only when the control that receives the focus has the CausesValidation property set to true.
For example, if you have written code in TextBox1's Validating event, and you click the OK button (CausesValidation = true) then the Validating event is raised, but if you click the Cancel button (CausesValidation = false) then the Validating event is not raised.

So I have a custom windows form with a tabbed browser. I want to be able to see the hoovered hyperlink in the status bar. I have searched everywhere but nothing yet.
I checked the MSDN under the web browser class which led me to the StatusTextChanged.
So in my code I have
wb.StatusTextChanged += MainWindow_StatusChange;
then
private void MainWindow_StatusChange(Object sender, EventArgs e)
{
WebBrowser wb = new WebBrowser();
this.toolStripStatusLabel2.Text = wb.StatusText;
}
Well, the tool.StripStatusLabel2.Text is empty.
Any help?
You have subscribed the wrong event.
Do this...
private void Form1_Load(object sender, EventArgs e)
{
WebBrowser wb = new WebBrowser();
wb.StatusTextChanged += new EventHandler(wb_StatusTextChanged);
wb.Navigate("http://www.google.de");
}
void wb_StatusTextChanged(object sender, EventArgs e)
{
this.toolStripStatusLabel2.Text = ((WebBrowser) sender).StatusText;
}
I cannot figure out how to catch the Navigating event on the WebBrowser control. Basically I'm trying to figure out how trigger the progress bar to show when a user clicks a link on a page.
Here is the code I use to show the progress bar and then hide it on page loaded. Can someone help me out with the event handler for Navigating?
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
progressBar.IsIndeterminate = true;
progressBar.Visibility = Visibility.Visible;
webBrowser.Navigate(new Uri(MY_URL, UriKind.Absolute));
webBrowser.LoadCompleted += new System.Windows.Navigation.LoadCompletedEventHandler(PageLoadCompleted);
webBrowser.Navigating = ?
}
private void PageLoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
progressBar.IsIndeterminate = false;
progressBar.Visibility = Visibility.Collapsed;
}
The documentation you seek is here. You can write
webBrowser.Navigating += webBrowser_Navigating;
// ...
void webBrowser_Navigating( object sender, NavigatingEventArgs e )
{
// ...
}
The answer of by VisualStuart helped me solve my problem.
My now working code is as below :
private void MyButton1_Click(object sender, RoutedEventArgs e)
{
MyprogressBar.IsIndeterminate = true;
MyprogressBar.Visibility = Visibility.Visible;
string site = MyTextBox1.Text;
webBrowser1.Navigate(new Uri(site, UriKind.Absolute));
webBrowser1.Navigating += webBrowser1_Navigating;
webBrowser1.LoadCompleted += new System.Windows.Navigation.LoadCompletedEventHandler(webBrowser1_LoadCompleted);
}
private void webBrowser1_Navigating(object sender, NavigatingEventArgs e)
{
MyTextBox1.Text = e.Uri.ToString();
MyprogressBar.IsIndeterminate = true;
MyprogressBar.Visibility = Visibility.Visible;
}
how can i set timeout for webBrowser navigate (url) event
c# netframework 4.0
By using a Timer of course. For example:
public void NavigateTo(Uri url) {
webBrowser1.Navigate(url);
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e) {
timer1.Enabled = false;
MessageBox.Show("Timeout on navigation");
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) {
if (e.Url == webBrowser1.Url && timer1.Enabled) {
timer1.Enabled = false;
// etc..
}
}
I am using following approach based on Navigating and Navigated events. The time between these two events are observed for redirecting to home pgae.
//Navigation Timer
timer2.Enabled = true;
timer2.Interval = 30000;
br.DocumentCompleted += browser_DocumentCompleted;
br.DocumentCompleted += writeToTextBoxEvent;
br.Navigating += OnNavigating;
br.Navigated += OnNavigated;
br.ScriptErrorsSuppressed = true;
br.Navigate(ConfigValues.websiteUrl);
private void OnNavigating(object sender, WebBrowserNavigatingEventArgs e)
{
//Reset Timer
timer2.Stop();
timer2.Start();
WriteLogFunction("OnNavigating||||||"+e.Url.ToString());
}
private void OnNavigated(object sender, WebBrowserNavigatedEventArgs e)
{
//Stop Timer
timer2.Stop();
WriteLogFunction("NAVIGATED <><><><><><><> " + e.Url.ToString());
}
private void timer2_Tick(object sender, EventArgs e)
{
WriteLogFunction(" Navigation Timeout TICK");
br.Stop();
br.Navigate(ConfigValues.websiteUrl);
}
