Hi, i have asp button like this:

<asp:Button ID="ImportToDB" runat="server" OnClick="ImportToDB_Click" />

And i need to call a javascript function when mouseover on this button. So i have in page_load():

ImportToDB.Attributes.Add("onmouseover","javascript:OnButtonMove(" + ImportToDB.ClientID + ")");

javascript function:

<script language="JavaScript" type="text/javascript">
 function OnButtonMove(id) {
         //something
 }
</script>

Everithing work fine only if button is enabled. but when i disable button, this javascript function will never fire.

what i am trying to do: I have button and when is something wrong i just disable it. And when user mouseover this(disable) button, I show him DIV with a message.

Can someone tell me why i cannot call this JS function while button is disabled?
