Hi There,

We found out that WebView's SetFocus() is working in Windows Form but not ASP.NET.

What we've tested:
1. Load google.com.
2. Focus the Search Text Box.
3. Press Tab 2 times to focus the Google Search button (a blue color border will be displayed on the button).
4. Capture the screen to confirm the button is focused.

The code below is working on Windows Form (webView1 is the WebView created automatically after added a WebControl to WinForm).

private void MyForm_Load(object sender, EventArgs e)
{
//Load page and wait for 5 seconds
webView1.LoadUrlAndWait("http://www.google.com");
EO.WebBrowser.WebView.DoEvents(5000);

//Set focus
webView1.SetFocus();
EO.WebBrowser.WebView.DoEvents(1000);

//Set focus on Search Text Box
webView1.EvalScript("document.getElementsByTagName('input')[3].focus();");
EO.WebBrowser.WebView.DoEvents(1000);

//Press Tab
webView1.SendKeyEvent(true, EO.WebBrowser.KeyCode.Tab);
webView1.SendKeyEvent(false, EO.WebBrowser.KeyCode.Tab);
EO.WebBrowser.WebView.DoEvents(1000);

//Press Tab
webView1.SendKeyEvent(true, EO.WebBrowser.KeyCode.Tab);
webView1.SendKeyEvent(false, EO.WebBrowser.KeyCode.Tab);
EO.WebBrowser.WebView.DoEvents(1000);

//Now the Google Search button is focus, capture the page to confirm the button is focused with blue border
webView1.Capture(System.IO.Path.Combine(System.IO.Path.GetDirectoryName(Application.ExecutablePath), "Test.jpg"));
}


Same code but the SetFocus() is not working in ASP.NET (We capture the screen and the Search Button is not with blue border):

protected void Page_Load(object sender, EventArgs e)
{
EO.WebBrowser.ThreadRunner threadRunner_ = new EO.WebBrowser.ThreadRunner();
webView1 = threadRunner_.CreateWebView();

threadRunner_.Send(() =>
{
//Load page and wait for 5 seconds
webView1.LoadUrlAndWait("http://www.google.com");
EO.WebBrowser.WebView.DoEvents(5000);

//Set focus
webView1.SetFocus();
EO.WebBrowser.WebView.DoEvents(1000);

//Set focus on Search Text Box
webView1.EvalScript("document.getElementsByTagName('input')[3].focus();");
EO.WebBrowser.WebView.DoEvents(1000);

//Press Tab
webView1.SendKeyEvent(true, EO.WebBrowser.KeyCode.Tab);
webView1.SendKeyEvent(false, EO.WebBrowser.KeyCode.Tab);
EO.WebBrowser.WebView.DoEvents(1000);

//Press Tab
webView1.SendKeyEvent(true, EO.WebBrowser.KeyCode.Tab);
webView1.SendKeyEvent(false, EO.WebBrowser.KeyCode.Tab);
EO.WebBrowser.WebView.DoEvents(1000);

//Now the Google Search button is focus, capture the page to confirm the button is focused with blue border
webView1.Capture(System.IO.Path.Combine(Server.MapPath("~"), "Test.jpg"));
});
}

We must set the focus on WebView in ASP.NET as our targeted page need to be focused in order to trigger some JavaScript/changes in element's class.

Please help. Thank you.

Hi There,

Thank you for the reply. We tested in Windows Application, the WebView's SetFocus is working even the WinForm is not in foreground, minimized or invisible.

In this case, is it possible to run/simulate a Windows Application in ASP.NET? We'are not familiar with Windows Application and tried to run a Windows Application like this in ASP.NET but the WebPage become an infinity loop and did not stop.

1.Create a WinForm and WebControl
2.Assign the WebView to WebControl
3. Add the WebControl to WinForm
4. Run the Window Application


Below is the code in ASP.NET's WebForm's PageLoad event:

protected void Page_Load(object sender, EventArgs e)
{
EO.WebBrowser.ThreadRunner ThreadRunner = new EO.WebBrowser.ThreadRunner();
webView1 = ThreadRunner.CreateWebView();

System.Windows.Forms.Form form_ = new System.Windows.Forms.Form();
EO.WinForm.WebControl webControl_ = new EO.WinForm.WebControl();
webControl_.WebView = webView1;
form_.Controls.Add(webControl_);

ThreadRunner.Send(() =>
{
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.SetCompatibleTextRenderingDefault(false);
System.Windows.Forms.Application.Run(form_);

//Load page and wait for 5 seconds
webView1.LoadUrlAndWait("http://www.google.com");
}
}

Hi There,

Thank you for the suggestion. We'll try it out.
