trigger the C# event handler and then follow up with the execution of a JavaScript function

I want to discuss the order of execution between a JavaScript function and a C# method:

Here is the code for a button in HTML:

 <asp:Button ID="MyBut" runat="server" OnClick="MyBut_Click" CssClass="MyBut" />

In C#:

 protected void MyBut_Click(object sender, EventArgs e)
        {....}

And in JavaScript:

$(document).ready(function () {
    $(".MyBut").click(function () { alert("!"); });
})

Currently, the JS function is executed first followed by the C# method. Is it possible to have the C# method execute before the JS function?

c#javascriptonclickonclientclick

Answer №1

Unfortunately, the C# method is triggered only when the server executes the back-end code during a page reload in an ASP.NET environment.

One solution could be to have the server-side C# generate client-side JavaScript that will run after the server-side code and page reload. Check out this example on how to inject JavaScript from asp.net code behind files: .

Alternatively, you could opt for using AJAX to call the server-side code instead of relying on code-behind. This way, you can control the sequence of events. For more information on implementing AJAX with ASP.NET, visit: http://www.asp.net/ajax.

Answer №2

When a button is clicked on a webpage, the JavaScript functions are executed before the C# code? This specific order of events must be followed. The JavaScript code embedded in the page responds to the button click action, triggers an event to the web server, and finally the C# logic is processed on the server side.
