Have just picked this up again.<br />
I am trying this but no joy as yet. &nbsp;For a start, attributes is not a member of the control class so it doesn't compile. &nbsp;The following compiles but doesnt find the body element. &nbsp;<br />
<br />
Dim cBody As HtmlGenericControl = Me.Page.Master.FindControl<wbr />(&quot;bodyRpMa<wbr />ster&quot;)<br />
&nbsp; &nbsp; &nbsp; &nbsp; cBody.Attributes.Add(&quot;onlo<wbr />ad&quot;, &quot;some_jscript&quot;)<br />
<br />
have set the body in the master to &quot;runat=server&quot; and id to &quot;bodyRpMaster&quot;<br />
<br />
I have put all this in the page load event.<br />
<br />
Am wondering what to do next

Hi <br />
<br />
Am using asp.net 3.5 with master pages.<br />
<br />
I need to run some javascript to preload some images in the body onload event but I don't need to run this on every page.<br />
<br />
The only body tag is in the master page (mp.master) for the site so currently the event runs for all content pages that whose masterpagefile is mp.master.<br />
<br />
How can I run js code in the onload event of some pages only.<br />
<br />
Can anyone help?<br />
<br />

ASP.Net body onload event with master pages

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
