ASCX files are written in text format, which means they can be opened and edited using a simple text editor such as Notepad or more advanced tools like Visual Studio. These files use the .ascx file extension, which is exclusive to ASP.NET Web User Controls. The code structure follows a hybrid of HTML and ASP.NET syntax with ASP.NET Server Controls being embedded within, allowing for the possibility of creating custom and dynamic web content.

Add the ASCX file to the web application folder.
Register the file using the <%@ Register %> directive within the ASPX page, specifying the src, tagname, and tagprefix attributes.
