Hi All and I hope someone can help us, We have a website with two levels of master pages. On the bottom level master, we use code-behind to set values for some labels such as page title and user name. This has worked fine for months until we converted our project into a web application. Now we are getting this error on the first page after login (ie the first to use the master page):
Server Error in '/' Application. Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] SageWeb.MasterPages_ABBlogoOnly.Page_Load(Object sender, EventArgs eEventArgs) +675 System.Web.UI.Control.OnLoad(EventArgs e) +131 System.Web.UI.Control.LoadRecursive() +65 System.Web.UI.Control.LoadRecursive() +190 System.Web.UI.Control.LoadRecursive() +190 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2427 Version Information: Microsoft .NET Framework Version:2.0.50727.3074; ASP.NET Version:2.0.50727.3601 These are the lines on the master page that seem to cause the problem (it works fine if we comment them out): Me.lblLoginLabel.Text = "Logged in as: " & SageLibrary.SageUser.CurrentUserName Me.lblLoginLabel.Visible = True Me.lblBrowserType.Text = "Using: " & SageLibrary.SageUser.CurrentUserBrowserType Me.lblBrowserType.Visible = True Me.lblScreenDetails.Text = "Screen size: " & SageLibrary.SageUser.CurrentUserScreenWidth & " X " & SageLibrary.SageUser.CurrentUserScreenHeight Me.lblScreenDetails.Visible = True Me.lblPageTitle.Visible = True Me.lblPageTitle.Text = Me.Parent.Page.Title.ToString In debug we have proved that all of the values called here are available. Any idea what could be causing the problem and why the conversion from project to web application triggered it? Many thanks if you can help NeilR
