ServerControl Randomly Null / System.NullReferenceException?
Apr 8, 2010
I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment.
The control is defined in markup. The accompaning codebehind is:
PGFMainNavi.HasAccessToFunction = HasAccessToNaviItem;
// HasAccessToNavi is a local function
Exception is:
System.NullReferenceException: Object reference not set to an instance of an object

I receive the following error in the code below: System.NullReferenceException: Object reference not set to an instance of an object. When I am logged into the page I do not receive the error. My Code:
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub SqlDataSource4_Selecting(ByVal sender As Object, ByVal e As SqlDataSourceCommandEventArgs) Handles SqlDataSource4.Selecting
Dim MemUser As MembershipUser
MemUser = Membership.GetUser()
UserID.Text = MemUser.ProviderUserKey.ToString()
e.Command.Parameters("@UserId").Value = MemUser.ProviderUserKey.ToString()
End Sub
End Class
I read the following online: You are trying to use a reference variable who's value is Nothing/null. When the value is Nothing/null for the reference variable, that means it is not actually holding a reference to an instance of any object that exists on the heap. You either never assigned something to the variable, never created an instance of the value assigned to the variable, or you set the variable equal to Nothing/null manually, or you called a function that set the variableto Nothing/null for you. The following is the Arthur's code example and his suggested fix which I am sure is right:
Private Sub TestString()
Dim a As String
If a.Length = 0 Then
Console.Write("Yes")
End If
End Sub

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

I want to extend the System.Web.UI.Page-class with some extra stuff.
In the ctor I need the value of a session-variable.
The problem is that the Session-object is null...
public class ExtendedPage : System.Web.UI.Page {
protected foo;
public ExtendedPage() {
this.foo = (int)HttpContext.Current.Session["foo"]; // NullReferenceException
}
}
If I move the part with the session-object into the Load-Event everything works fine...
public class ExtendedPage : System.Web.UI.Page {
protected foo;
public ExtendedPage() {
this.Load += new EventHandler(ExtendedPage_Load);
}
void ExtendedPage_Load(object sender, EventArgs e) {
this.foo = (int)HttpContext.Current.Session["foo"];
}
}
Why is the Session-object null in the first case??

I'm trying to encrypt some userData to create my own custom IPrincipal and IIdentity objects using Forms authentication - I've serialized an object representing my logged in user to Json and created my FormsAuthentication ticket like so:
string user_item = GetJsonOfLoggedinUser();/*get JSON representation of my logged in user*/
System.Web.Security.FormsAuthenticationTicket ticket =
new System.Web.Security.FormsAuthenticationTicket(1,
WAM.Utilities.SessionHelper.LoggedInEmployee.F_NAME + " "
+ WAM.Utilities.SessionHelper.LoggedInEmployee.L_NAME,
DateTime.Now, DateTime.Now.AddMinutes(30), false, user_item);
string encrypted_ticket = System.Web.Security.FormsAuthentication.Encrypt(ticket);
HttpCookie auth_cookie =
new HttpCookie(System.Web.Security.FormsAuthentication.FormsCookieName, encrypted_ticket);
Response.Cookies.Add(auth_cookie);
However, the string encrypted_ticket is always null. Is there a limit on the length of the user_item string?

I need to refresh my webpage in case of a change in the system time. However I see that my session variables are becoming null when the system time changes. So I cannot perform the refresh action since my webpage requests a login.I am not setting the Session variables to null explicitly anywhere in the code. I can't seem to figure out how they are becoming null.

I'm working on a Navigation Menu. I've created below ServerControl and it works, but I want to allow users adding some standard ASP.NET controls within my ServerControl Tags like label, image and so on.
<MdsMenu:ServerControlMenu ID="ServerControlMenu1" runat="server">
<MdsMenu:animation AnimationSpeed="Normal" AnimationType="Opacity_Height" Delay="1000" DropShadow="true" />
<!-- HERE HAS TO HAVE SOME STANDARD ASP.NET CONTROLS -->
<!-- e.g <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> -->
</MdsMenu:MenuItem>
</MdsMenu:ServerControlMenu>
My problem is here that how I can get Child Controls within <MdsMenu:MenuItem> and show them like as they are in the output. P.S: I overwrite RenderContents method
protected override void RenderContents(HtmlTextWriter output)
{
output.Write(OutPutStringBuilder.ToString());
}

I've written a ServerControl that contains a significant amount of javascript, and I'm using IScriptControl to pass parameters from the server code to the javascript. The javascript file is configured as an embedded resource, and a script reference to the file is being injected into the html by IScriptControl.GetScriptReferences(). The ServerControl is contained in a DLL assembly. When I use the control in a test page everything works fine.
What I want to do is to extend the control - to derive a new control from it, in a second assembly, that provides some extended functionality. (The first assembly contains code that is shared across customers, the second code that is shared across several projects for the same customer). So, my problem: I create a new ServerControl that derives from the first, but doesn't yet provide any new functionality.
[Code]....
Then I change my "<%@ Register ... %>" tag in the test page to reference the derived control. Things compile just fine, and the code-behind runs fine, but I get an undefined variable error in javascript. Sys.Application.add_init() is calling $create(), passing the <namespace>.<classname> of the javascript class, and it's throwing an error on the namespace.
Now, the namespace is registered on the first line of javascript file. Which makes it look like the javascript file might not be being included, when using the derived control. So I stuck a "debugging" line in front of the Type.registerNamespace(). Using the base control, the debugger breaks as it should. Using the derived control, it does not.
So, I look at the script includes in both versions of the page. They are identical. The sources are src="/testing/WebResource.axd?<random junk>", or src="/testing/ScriptResource.axd?<random junk", so I'm not sure which one refers to my embedded javascript file, but whichever one it is, the includes are identical between the page using the base control that works and the page using the derived control that does not.
