    Default Running ExtJS 5 using System.Windows.Forms.WebBrowser

    Has anyone successfully used System.Windows.Forms.WebBrowser to initiate an ExtJS 5 application?


    My application works correctly when run directly in a browser but does not run correctly if initiated using System.Windows.Forms.WebBrowser. The application works correctly using the WebBrowser in version 4 but when run in version 5 I am having a problem with the combobox field. If I first click into the text part of the field, an item can be selected from the drop down list. However, if I first click on the down arrow, the item I select from the drop down list is ignored and is not saved in the field. I have another similar problem with the right click context menu. The application seems to be ignoring the selection made in the context menu. Any ideas on what could be causing these problems?

    I don't believe that is supported, but hopefully someone has some experience to share. Haven't used it before -- does it emulate IE?

    The System.Windows.Forms.WebBrowser uses the installed version of IE to allow a web program to be initiated inside a Windows Forms application. Dropping support for IE6/7 in ExtJS 5 seems to be causing a problem with the WebBrowser.

    Indeed, Ext JS 5 only supports IE 8 and up.
