Problem in child page with Hyperlink.Attributes.Add
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.
