Events triggered by client-side interactions with ASP.NET controls

Below is the image code I'm working with:

<asp:Image runat="server" ID="imgLogo" Style="border-width: 0px; max-width: 100%; max-height: 200px;" onerror="showInvalidImageMessage();" onload="imageChanged()"/>

Even though I want to trigger a JavaScript event, it seems to be looking for a server-side handler.

Using jQuery's on, bind, or live methods won't work in my case since the image control is generated dynamically.

When it comes to client-side events, we typically use onclientclick for ASP buttons. I've also tried using onclientload, but it doesn't seem to work. Is there a way to achieve this using pure JS?

Answer №1

Utilize the Image control to manipulate images directly from server code. This control allows you to showcase any compatible image supported by the visitor's browser on the webpage.

The OnLoad attribute is specifically designed to attach an event handler to the Load event, a server-side event rather than a client-side event.
