How to exit an ASP.NET application by pressing the exit button

I am new to asp.net and currently using Visual Studio 2012.

Currently, I am working on a login page where I have two buttons: Login and Exit.

Whenever I click on the Exit button, I want the application to close and also stop the debugging process.

I came across a solution on this link where various approaches are discussed, but I prefer the following method:

    protected void Page_Load(object sender, EventArgs e)
    {
        ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
    }

Furthermore, I wrote the following javascript function within the Login.aspx file:

<script language="javascript" type="text/javascript>"
    function CloseWindow() {
        window.close();
    }
</script>

Note: While the above script successfully closes the application when I click on the Exit button, it also closes the application when I click on the Login button, and debugging does not stop as intended.

Answer №1

Your webpage is fulfilling its intended purpose successfully.

During the Page_Load event, you invoked:

ClientScript.RegisterOnSubmitStatement()

This function causes all form submissions to trigger the specified script; this means that all buttons will execute your CloseWindow procedure upon being clicked.

If you wish for only a single button to close the window, then you should only assign the CloseWindow method to that specific button. The chosen solution in the provided link is effective because there is only one button present. Alternatively, you could opt for a different approach, such as:

OnClientClick="javascript:window.close();"

adding this attribute to your Exit button.

Answer №2

Take a unique approach and handle the two buttons individually. Feel free to customize the login button for submitting the page and managing the postback without linking any events to the CloseWindow() function. Then, create and manage the Exit button like this:

<input type="button" onclick="CloseWindow();" value="Exit"/>

A helpful tip is to set Internet Explorer as the default browser for debugging in the debug toolbar.

Unlike a winforms application, an ASP.Net application is stateless. The code running in the browser does not rely on the same resources as the code in the Visual Studio debugger. Their only connection is through the requests made by the browser to the server (VS 2012 debugger acts as a server or uses IISExpress) and the responses received from those requests.

In general, when you close the browser, the server continues to operate, awaiting more requests. Internet Explorer behaves uniquely compared to other browsers with Visual Studio. When the IE instance launched by Visual Studio is closed, the debugger process also closes.

If you are just beginning with ASP.Net, consider exploring the ASP.Net MVC framework. It offers a cleaner separation between server and client side code, potentially helping you avoid similar issues in the future.
