To embed Exago within a WinForm application the following properties should be set within the WebReportsCtrl line of the .aspx page that contains Exago (default is Exagohome.aspx).
The example below shows these properties being set to force emulation of IE9 and make Exago aware that it is running within a WinForms application.
<wr:WebReportsCtrl ID="WebReportsCtrl" runat="server" BrowserEmulation="IE9" WinFormsApp="true" />
NOTE. The Host application can disable right clicking within Exago by setting the property IsWebBrowserContextMenuEnabled on the browser control to False.
