I have one class library project created, there is one class BaseUIController in that, I want to write Navigate() method in the class would work as good as Response.Redirect("URL")
Function declaration is:
public void NavigatePage(string URL)
Please tell me how can I implement it, because System.Web.UI is not avaliabe in class library type projects, so I can'nt use Response.Redirect(URL).
Please guide me.
From a good design perspective, you should let the class library simply return a value that you use to determine where to redirect to in the presentation layer (the .aspx pages). By letting the class library redirect users, you tie it to a web application, which limits its reuse possibilities.
That said, you can add a reference to System.Web in your class library. Then you access objects like Response and Session in the class library like this:
I tried using the system.web.httpcontext.current.response.redirect(" mypage.aspx"); in the class library... but in runtime, its specifying that the object is null and not set to an instance. any ideas??? what do i need to do as alternative.
I have the same issue as Red_October. I have a button and the code behind for the button is
when click on the button, system give this error "Object reference not set to an instance of an object"
I have a SharePoint site http://moss2007
I have a page on this site call ViewMyStaff.aspx (this is just a blank webpart page). when the user clicks on the button, system should take me to http://moss2007/Pages/ViewMyStaff.aspx page. The form library is in the same site collection as this page
I have the same problem, in my case I am trying to do the redirect from a VB.Net module, here is the code:
Public Sub ShowEPSErrorPage(Optional ByVal strErrorMessage As String = gGenericErrorMessage,Optional ByVal strDetailedMessage As String = "")
I have System.Web imported and as I said this is in a module which is part of my web application.
When I debug this, sometimes the debugger will be able to evaluate HttpContext.Current and sometimes it would tell me "Unable to evaluate expression", but either way this throws an exception with a message "Unable to evaluate expression"!! the path is proper so I am not sure what am I missing or doing wrong?
