I'm embarrassed to ask this here because it's clearly been duplicated several times already on StackOverflow. I've read a lot of stuff including:
[URL]
I think I've done exactly what those article say, but it's not working for me.
Here's the top of my master page, named "MasterNoNews.master":

In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.

Here's the scenario: A class based on System.Web.UI.Page has been created. A number of content pages derive from this class. All of these content pages use the same master page. The content pages define controls which need to access things on the master page (in code-behind). This is fine - no problem. In particular, each content page has its own data grid. The grid on each page has the same name, so that common code can reference it. In fact, some event handling for the grids on each content page is identical, so would like to factor that code to the base class. Interestingly, I can actually define the event handler entirely in the base class, with no stub in the content class at all, because the wire-up of event handlers uses the event-handler name defined in the grid, and that name happens to be found in the inherited base class. All good and dandy... very cool in fact. The problem comes when the code in the base class needs to access any of the common elements from the content page's master. Remember, the master is the same, and I know the type of the master. I would like to do something like this in the base-class code:
((myMasterType)this.Master).PropertyofMaster=xxx;
The problem is, that myMasterType - the type of the master page the content pages are using - is not available at compile time, at least not from a class definition for a base page. I've found articles that claim that the class name of the master is available - and it is, but not from a separate class. I CAN see it and compile with the master's class name from, for example, the code behind of the various content pages. But the actually class simply isn't available, it seems, from a pure class (the base page class). Judging from other times this question has been asked, here are common misunderstandings offered as solutions: 1. Use a page directive to declare the master type. This is not even vaguely a part of the problem, as the issue is not code in the content page, but in a separate base class which content pages inherit from. That base class is a pure class -- no .ASPX file at all. 2. Pass a reference to the master object from the content page to the base class. This can be done, but is pointless, because I can already get it, using "this.Master" from the base class! But because the type of the master is not available at compile time from the base class, it can't be passed from the content page either - unless it is passed with type MasterPage, thus losing all the properties/methods publically defined in the specific master page class. 3. Move the base page class out of the App_Code folder because the app_code folder is compiled before the other classes, and thus before the master page class. Doesn't work -- put the master page class file right in the same folder with these content pages and their master page, and the master page class is still not available at compile time from within the class. Re-summarized: Base page inherited by content pages. Content pages all use a common master page. Want to access the public properties of that master page from the base page, at runtime. Barrier is that I can find no way from within the base class to cast the master page object to the actual master page subclass being used.

I'm working on a project that uses a master page. When the page loads I'm calling a class (which I feed and ID into) to get back certain values for a location that the user has selected. Things like town name etc.
On the home page I have a user control which has some statistics for that location too.
Is there a way that I can get the user control to pull values from the class invoked by the Master Page (which has already been fed the ID, hit the db and pulled back the values), rather than creating a new instance of the class within the user control and having to supply the ID and hit the db all over again? This is now I'm calling the class in the masterpage. I have a method "CheckForStoredLocation" that goes off and gets all the data I need.

I have following environment:
masterpage with a contentPlacholder multiple pages which use this masterpage and implement a base-class (fooPage) fooPage has a certain property (fooProperty)
[Code]....
Obviously this is not going to work - but how can I achieve this?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty as a parameter - but i would like to rather have a pull-system in this case...

I have a property on my Global.asax.cs class that I need to access from a business class, i.e. using HttpContext.Current. How do I do this? Global.asax.cs (in a web project)
public partial class Global : System.Web.HttpApplication
{
public static ProxyGenerator Generator = new ProxyGenerator();
Business class (in a separate business project)
var generator = ((Sei.Osp.Web.Global)HttpContext.Current.ApplicationInstance)
This obviously doesn't work and I don't want to reference the whole web project in the business project as it will create a circular reference (the business project is already referenced in the web project)
UPDATE:
To clarify - the property I'm creating holds an instance of the Castle Dynamic Proxy Generator class. I've read that you shouldn't just create this all over the place. So I thought I'd create it in my Global.asax.cs and then just use that instance wherever I need to create a proxy class (I'm using it to do AOP) Is there a better way of doing this?

Currently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.

I have added a static string variable inside a web page with it's class named VersionBase. The class is public, the variable is public, why can't I simply do VersionBase.MyString from anywhere inside the project like I can do with any other class?

I am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.
Is there any way to access that class directly from the aspx page?
I know that i can make a method like:
width="<%= getWidthSize() %>"
and inside the aspx.cs to define this method to take the size from that static class.
But i am asking if this could be directly managed from the web aspx page...?

I am making a JSON call to web method which is defined in code behind. The web method returns a class object.The class returns 3 properties one of type list and 2 integers. I am accessing these in the following manner:
success: function(result) {
alert(result);
alert(result.LookCount);
alert(result.length);
if(result.LookCount > 0)
{
var Info = "";
for(var i = 0;i < result.LookUps.length; i++)
{
Info += CreateLookUpGrid(result.LookUps[i].Client,result.LookUps[i].ClientOrg);
}
alert(result.LookCount) -> alerts undefined and when i alert result it shows me the compelte result string which has all data. So the data is returned correctly by web method. But I am unable to access it.

Here When i create object of Class InheritingOneConstruntor value of public field var1 is zero at last. But when i checked step by step through debugging i found that when base class's New() constructor is called, for a moment all var1's value becomes 89. All var1 means at all locations where var1 is used i.e., in base class and in child class.But the moment control exits New() constructor of base class, var1's value again becomes zero. Why it happend ?

I have searched high and low (and very possibly could have missed it), but in my years of programming, I have always come across one practice that seemed to be the standard in OOP, which is to use private properties in an object with public methods to manipulate the data.
However, the more I delve into ASP.NET (specifically with MVC), the more public properties I see inside of classes (specifically models) such as the ones shown at Scottgu's blog discussing the Entity Framework.
Does it have something to do with the way that LINQ populates a class?
