问题
I am using WebBrowser control of .NET to login into a website. When i click on a button that popups a new window the popup window asks me to login again. However i am not asked to login again if i open the webpage in internet explorer. Is there any way to make the WebBrowser control store session so that i do not have to login again on the popup window.
回答1:
To maintain the session state you can use the NewWindow2 event to open the new page in another form in the application; the event is triggered by the WebBrowser control.
See How to use the WebBrowser control NewWindow2 event in Visual C#
回答2:
before clicking that button are you already made login?just asking.
in both cases i think solution which i am going to give will work for you.
for this purpose i think you place login fields in panel and on page_load check either session empty or not if not then visible it false if yes then visible it true.
Hope you find the answer.
