You have to give the panel a discrete size. &nbsp;E.g.,<br />
<br />
Width=&quot;100px&quot;<br />
Height=&quot;100px&quot;

&quot;Discrete&quot; may not be best word choice, as you could also use<br />
<br />

...perhaps &quot;distinct&quot; or &quot;defined&quot;? &nbsp;lol

Why panel BackColor does not show?

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.

.NET Programming

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

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
