Hello

We have a wpf application and we have a weird behaviour in different windows OS, when from our first webview we try to open a new window with a new webview (meaning the site from the first webview calls a web_view_NewWindow handler).
Our problem is particular when the new webview is expected to load pdf responses(but can appear in html responses too).

We try different approaches in coding. The problem seems to be in the web_view_NewWindow handler.

->First we try to make a [newWindow.gridMain.Children.Add(newWebControl)]

In windows xp if we add [e.Accepted = true] then the whole application halts.
In windows8 32bit the new window never loads.
In windows7 64bit everything works fine.

->Second we try to have a xaml inside of which we have a webview(in xaml too) and from the web_view_NewWindow we just
show the new window and change the webview's url.

if we add [e.Accepted = true] then in windows7 the new webview never load.So we skipped it.
Our code now is
PdfWindow newWindow = new PdfWindow();
newWindow.wc.WebView.Activate += new EventHandler(web_view_Activate);
newWindow.wc.WebView.Url = e.TargetUrl;
newWindow.Show();

Unfortunately,
In windows XP most of the times the 2nd webview does not load the url and we see a white screen.But newer halts the application as before.
In windows7 64 bit everything works fine.
In windows7 32 bit some times the 2nd webview does not load the url and we see a white screen.
In windows8 everything works fine.


Any ideas?

Thank you in advance,
Kyriakos

We change our code in the event handler to:

e.Accepted = true;
PdfWindow newWindow = new PdfWindow();
newWindow.wc.WebView.Activate += new EventHandler(web_view_Activate);
newWindow.wc.WebView = e.WebView;
newWindow.Show();

but as i mentioned earlier in windows xp we have the same problem. If i skip the e.Accepted = true then i have the same problem in windows7.

I can provide you with a sample project if necessary.

Thank you for your immediate response earlier
