Default Problem in child page with Hyperlink.Attributes.Add

Hello All,

I am having a weird problem Hyerlink.Attribute.Add("onclick"). The code i am using is as foolwing -

HyperLink h1 =(HyperLink)Form.FindControl("hlnkPatienType");
h1.Attributes.Add("onclick", "window.open('TypePatient.aspx',null,'left=700 , top=50, height=600, width= 500, status=n o, resizable= no, scrollbars= no, toolbar= no,location= no, menubar= no');");

I am writing this code in Page_Load event.This code works perfectly fine when used in a simple form. But as soon as i added a master page and had written this code in child page it is showing me "Object Reference not set to an instance of an object." error. Can someone please help me to fix it. Thanks in Advance.

If the hyperlink is on the form and not in another containing control, then there is no need for the findcontrol(). Now, since you have put this code on a content page, you are getting the error because the form is actually on the masterpage, so, it will not find a form on the content page. So, remove the findcontrol().
