C# webbrowser control focus issues

[Wheels012]

Good afternoon. I have a webrowser control on my main form and on the form load I set the URL for the control When the webpage loads, the focus stays on the webpage and I cannot seem to programatically move the focus to the combobox on the form. I even set the focus on the webbrowser control to False. Any suggestions? Thank you, WHEELS

Set the ComboBox on the top in the tab order. If that doesn't work, hook up a method to the DocumentCompleted event of the web browser control and set the focus to the ComboBox there.

Hi Shameel. I did experiment with DocumentCompleted yesterday before I posted, but neither 'method' worked. Not sure hwy DocumentCompleted doesn't work though. However, I did get this to work:

private void WebBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
{
this.cboSP_Site.Focus();
}

I appreciate your willingness to assist. Have a great day, WHEELS

ProgressChanged would fire more than once (probably many times) during a single page load, so you end up setting focus many times :)

I noticed that, but what can I do? WHEELS

DocumentCompleted SHOULD fire when document is completed loaded. Try to find out why it is not working.

Thank you Shameel. That will be my primary focus today. However, one thing I noticed, is that some web pages hijack the focus (e.g. Google), 'holding' it in the search box. My feeling is that when this occurs, the DocumentCompleted will not fire. WHEELS

I just created a small app to see myself what the problem is, and as you said, setting focus to the other control in DocumentCompleted event doesn't work. The reason I found is that DocumentCompleted is fired when the browser completes loading the html content of the page and google runs a javascript in its onload event to set focus to the search box. This happens after the DocumentCompleted event executes and therefore focus goes back to the control. But ProgressChanged event works, and I found a workaround to do away with setting focus multiple times. Use this code:

private void webBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e) {
if (e.CurrentProgress == e.MaximumProgress) {
textBox1.Focus();
}
}

Works great. Thank you. WHEELS
