What is an ASCX file?

ASCX files mostly belong to ASP.NET by Microsoft. An ASCX file is a script containing a definition of custom, reusable user control for an ASP.NET-based web application. A user control is a single component of a website which is reused across multiple pages through the "include" directive. A single ASCX file contains the script and markup for a component such as a form, a navigation bar, or a web page footer which is imported into various web pages of a website. Visual Studio integrated development environment is the primary program for creating and editing an ASCX user control file.

How to open ASCX files

You need a suitable software like ASP.NET to open an ASCX file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ASCX file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ASCX file directly in the browser:. Just drag the file onto this browser window and drop it.
