I have a website that has multiple parameters in a query string. I tested that this url works in firefox and chrome. When i run it in EO.WebBrowser I get an error.

If I change the _URLName to only contain one querystring everything works just fine.

I am using your sample and I modified by assigning a url to _URLNAME like below:

_URLName = "http://localhost/configcontainer/config_container.html?XFRCUDID=5695661282513041653081747&CONFIGID=XXX5710107531217641649082&MODEL=PL10&Opt1=1&Opt2=1";

LayoutFileXML = "<?xml version='1.0' encoding='utf-16'?>" +
"<DockContainer Version='1'>" +
"<Views>" +
"<DockView IsActive='true' IsDocumentView='true'>" +
"<Items>" +
//"<Item ItemId='WebView:' StateData='https://www.google.com/' />" +
"<Item ItemId='WebView:' StateData='" + _URLName + "' />" +
"</Items>" +
"</DockView>" +
"</Views>" +
"</DockContainer>";





And then I assign it like this:
m_DockContainer.LoadLayoutXml(LayoutFileXML);

And get this error:
'=' is an unexpected token. The expected token is ';'. Line 1, position 262.

the XML was copied from a file created by your sample app???

Obviously.
