I have a master page with a form element and the defaultbutton attribute set to a server-side ImageButton. On one of my pages I want to "override" the masterpage defaultbutton attribute by setting the Forms DefaultButton in the Page_Load event.
i.e On mater page:
<form id="form1" runat="server" defaultbutton="btnSearch">....</from>
On the page Page_Load event that "override" the master page attribute:
this.Form.DefaultButton = this.ibRecalc.ID;
It errors with :
The DefaultButton of 'form1' must be the ID of a control of type IButtonControl
I am using image buttons which implements IButtonControl
Any ideas of what I might be doing wrong or a different way to approach the problem?
Thanks
