WebPart onload Javascript event

This is doing my poor little head in. I want when the web part loads, for it to fire a Javascript function

So here is the current code


	protected override void RenderWebPart(HtmlTextWriter output)
		{
            System.Web.UI.HtmlControls.HtmlGenericControl ScriptControl = new System.Web.UI.HtmlControls.HtmlGenericControl("script");

            ScriptControl.Attributes.Add("type","text/javascript");
            ScriptControl.Attributes.Add("src",this.ClassResourcePath + "/ad_rotator.js");

            this.Controls.Add(ScriptControl);

            this.Attributes.Add("onload","DoSomething();");


            

			RenderChildren(output);
			output.Write(SPEncode.HtmlEncode(Text));
		}

Only thing it does not do so..Is there another way of doing it, I was thinking onmouseover, but i would prefer it not having to be user activated.

So basically this is a question on how to do an onload without having to use onload, is there an onRender event or somthing??? Or a different way to add the attribute onload that it will fire when the webpart is displayed

Im not too up to speed on the web side of c# but what html does it generate? I assume that "this" refers to the html doc? If so is this.attributes.add() not adding it to the <html> tag? Should the onLoad not be on the <body> tag? Can you get access to the body tag in code and attach the onLoad to it?

Actually its a Sharepoint WebPart so not a HTML doc at all. Its a DLL thats loaded at runtime.

I checked the HTML and there is no onload event on the web part but on on the image that is loaded first time. So I think I can use that.

Just see how it goes now..

Actually invoking _spBodyOnLoadFunctionNames.push("") will allow you to put your function in as a onload event.

So that might also work
