Can anyone tell me why this is not working ?

I have an aspx page with the following definition,

<asp:ImageButton ID="MenuBtnOpen" ImageUrl='<%#
Page.ClientScript.GetWebResourceUrl(typeof(WebResources.Resource),
"A.gif")%>' />

When the page is processed by asp.net, the src attribute for the image
is always blank.

If I put this code in the Page_Load event,

MenuBtnOpen.ImageUrl =
Page.ClientScript.GetWebResourceUrl(typeof(WebResources.Resource),
"A.gif");

It works ok.

Ive spent an entire day trying to work this out.

Please tell me im doing something stupid and its not a bug in asp.net.

<%#... %> refers to a databinbing exptression and you need to call 
control.DataBind() or Page.DataBind() for it to be evaluated., 
Page.DataBind() binds the entire page (also child controls) while 
control.dataBind() binds a specific control and its child controls.
