Web Forms :: Unable To Access Master Page Control?
Apr 26, 2010
I am using asp.net 3.5 with C# to build web application. I am using master pages. I had a label in masterpage. I want to set some text in that label from content page. I have written following code for that
Label lbl = (Label)Master.FindControl("lblUserName");
lbl.Text = "Guest";
but it is giving an exception "Object reference not set to an instance of an object." What could be the problem, if sombody can put some light on it.

Below is my Aspx code and code-behind:

My master page code looks something like this:
namespace Recipes
{
public partial class MasterPage : System.Web.UI.MasterPage
{
...
public void UpdateUserLogin()
{
NicknameLbl.Text = ((Recipes.BasePage)Page).CurrentUser.Nickname;
}
...
}
}
I want to call the UpdateUserLogin() method from a user control, something like this:
((Recipes.MasterPage)this.Page.Master).UpdateUserLogin();
But for some reason the compiler doesn't know Recipes.MasterPage (are you missing an assembly blablabla).
Maybe the problem is that I added the Recipes namespace around MasterPage manually, it wasn't added by VS. By the way I'm using VS Web Developer Express 2008.

We have created a Master page that inherits off the asp.net Master class.We have also got ui controls that inherit off the standard asp.net ui control class.Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use.However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

I have seen numerous posts with this problem, however none of the solutions have worked for me. I am using asp.net 4.0 forms authentication. I have the following set in my config file.
<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" />
</authentication>
<authorization>
<deny users="?"/>
</authorization>
The login.aspx page uses a master page and styles in a stylesheet located in a folder off the root directory called 'Styles'. I have also add the following to my config file.
<location path="~/Styles">
<system.web>
<authorization>
<allow users = "*"/>
</authorization>
</system.web>
</location>
When the page displays, the login page displays with the master page content, however all of the styles are missing. When I embed styles into the master page the styles show properly, so I know the problem is that the styles are not being accessed from the file. how I can authorize access to the stylesheet?
