<div>
<div class="content wysiwyg-content">
Ok, so I have an .aspx file that is vb. I have code in the code-behind that relate to items on the .aspx page.<br />
<br />
I get errors from time to time on the code-behind that state:<br />
<br />
&quot;txtxYZ&quot; is not declared. It may be inaccessible due to it's protection level.<br />
<br />
I cannot figure out why I cannot always reference elements on the form from the code-behind. I'm not an expert but I understand the basic concepts and it does work on other pages. This one, however, it isn't. I have run into this before and just start a new web form but I'm bothered by why it happens.<br />
<br />
Any thoughts?

Basic .Net Concept with MasterPages and CodeBehind

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
