Recently, we have been experiencing filename extensions that leave us scratching our heads. For example, files like HEIC, XAPK, and standard FLAC files can turn up; therefore, you might not know what to do with them. A perfect example of this is the ASPX file, where you might not know what an ASPX file is used for. But it can irritate you as Windows does not know what to do with them by default. So Microsoft made the file format. However, it is possible to open the .aspx files.
But it isn’t necessary to do this if you work in IT on web servers or web development. You should know that .pdf, .jpg, and other file types can sometimes appear as them. Let’s dive into the article to learn what is a .aspx file and how do I open it.
What is an ASPX file?
ASPX, Active Server Pages, is a file format that web servers use. It is created using Microsoft ASP.NET, an open-source development framework. Web developers use it to make dynamic web pages using the .NET and C# programming languages.
It iterates on the ASP, a technology that precedes it. But it never uses Microsoft’s .NET language. Rather than that, you can find the File written in other frameworks. For example, it is known as a .NET Web Form. Besides, it is possible to determine if a web page is written in ASPX while a ‘.aspx’ suffix is applied to the URL.
These files can contain different scripts or other open-source files browsers receive from web servers. In addition, these are web service components that can offer dynamic elements on a page. If you are an end user, you cannot see or interact with these file types during the online experience. But when they do it, you can experience an error with the web service’s configuration. Let’s know more details about what is an aspx file extension.
More Information:
These pages are known as “.NET Web forms.” It is possible to recognize these pages in a web browser using the URL in the address field ending in .aspx.
Microsoft developed and released it in 2002 to succeed Active Server Pages (ASP). Web developers use this web app framework to create dynamic sites and apps.
Common ASPX File Names:
Default.aspx is a default webpage. It is loaded if a client browser requests a web server directory on a Microsoft IIS-based server. In this case, the server, which is Microsoft IIS-based, must use ASP.NET.
For instance, if a client requests HTTP://www.sampledomain.com/, the server will load the following URL HTTP://www.sampledomain.com/Default.aspx unless you configure it to load another one.
How Do You Convert .ASPX to HTML?
The HTML ones are static. Therefore, if you convert this type to HTML, you might lose all the dynamic elements of the page. If you are willing to convert it, load the page in your browser and tap on it. After that, you should tap on the View Page Source and save that to the local HDD. You may try to load this. It will appear on your page, but nothing will work.
Programs to Open ASPX File on Different Devices:
Programs depend on which type of device you use. Therefore, we have given names of the supported programs for different devices.
Windows:
- File Viewer Plus
- Microsoft Visual Studio 2019
- ES-Computing EditPlus
- Adobe Dreamweaver 2020
- Any Web browser
Mac:
- Adobe Dreamweaver 2020
- Any Web browser
Linux:
- Any Web browser
Android:

.ASPX File Format:
ASP.NET web forms depend on the event-driven model to interact with the web app. In this case, the browser submits a web form to the server as an end user. In return, the server returns a full markup page or HTML page. Besides, the ASP.NET component model can provide an object model for these pages. The model describes:
Thre are server side counterparts of all HTML elements or tags, like <form> and <input>.
Server controls are used to develop the most challenging user interface, like the Calendar or the Gridview control. These use the ASP.NET Code Behind model to create pages.
In-Line Code:
It is a sample code that can offer all the functionality for user implementation. This code displays a sample ASP.NET page with inline code:
<%@ Language=C# %>
<HTML>
<script runat=”server” language=”C#”>
void MyButton_OnClick(Object sender, EventArgs e)
{
MyLabel.Text = MyTextbox.Text.ToString();
}
</script>
<body>
<form id=”MyForm” runat=”server”>
<asp:textbox id=”MyTextbox” text=”Hello World” runat=”server”></asp:textbox>
<asp:button id=”MyButton” text=”Echo Input” OnClick=”MyButton_OnClick” runat=”server”></asp:button>
<asp:label id=”MyLabel” runat=”server”></asp:label>
</form>
</body>
</HTML>
Code-Behind:
You can write the code and store it in separate class files for clean separation of HTML from presentation logic. As a result, the presentation layer becomes independent of the executable code. It is the code-behind for presentation purposes.
<%@ Language=”C#” Inherits=”MyStuff.MyClass” %>
<HTML>
<body>
<form id=”MyForm” runat=”server”>
<asp:textbox id=”MyTextBox” text=”Hello World” runat=”server”></asp:textbox>
<asp:button id=”MyButton” text=”Echo Input” Onclick=”MyButton_Click” runat=”server”></asp:button>
<asp:label id=”MyLabel” runat=”server” />
</form>
</body>
</HTML>
The genuine logic’s C# implementation for the presentation layer is as follows:
using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace MyStuff
{
public class MyClass: Page
{
protected System.Web.UI.WebControls.Label MyLabel;
protected System.Web.UI.WebControls.Button MyButton;
protected System.Web.UI.WebControls.TextBox MyTextBox;
public void MyButton_Click(Object sender, EventArgs e)
{
MyLabel.Text = MyTextBox.Text.ToString();
}
}
}
