Call onresize from ASP.NET content page

I have a JavaScript method that I need to run on one of my pages, in particular, the onresize event.

However, I don't see how I can set that event from my content page. I wish I could just put it on my master page, but I don't have the need for the method to be called on all pages that use that master page.

Any help would be appreciated.

How about use code like the following in your Content Page (C#)?

Page.ClientScript.RegisterStartupScript(this.GetType(), "resizeMyPage", "window.onresize=function(){ resizeMyPage();}", true);

Thus, you could have a resizeMyPage function defined somewhere in the Javascript and it would be run whenever the browser is resized!

I had the same problem and have come across this post :

IE Resize Bug Revisited

The above code works but IE has a problem where the onresize is triggered when the body tag changes shape. This blog gives an alternate method which works well

Place the following in your content page:

<script type="text/javascript">

// here is a cross-browser compatible way of connecting 
// handlers to events, in case you don't have one
function attachEventHandler(element, eventToHandle, eventHandler) {
    if(element.attachEvent) {
       element.attachEvent(eventToHandle, eventHandler);
    } else if(element.addEventListener) {
       element.addEventListener(eventToHandle.replace("on", ""), eventHandler, false);
    } else {
    element[eventToHandle] = eventHandler;
  }
}

attachEventHandler(window, "onresize", function() {
    // the code you want to run when the browser is resized
});

</script>

That code should give you the basic idea of what you need to do. Hopefully you are using a library that already has code to help you write up event handlers and such.
