ASCX files make it easy to use the same code across multiple ASP.NET web pages. For example, ASPX files on a website might link to a single ASCX file for the site’s navigation menu. They are user controls for embedding in pages or websites.
ASCX files are plain text that can use code behind like web pages ending in .ascx.cs. Markup code starts with @Control directive. 303 file types have the ASCX extension, but most are not compatible. The ASP.NET User Control Format file was likely created in Microsoft’s Opera program.
Tips to open ASCX files: Use tools compatible with *.ascx files. Probably cannot convert them to anything else. ASCX files are components of ASP.NET web development. They contain reusable user interface elements with web controls, code and markup.
