I want to call a javascript function of parent page where iframe is placed. from the page inside an iframe.
i  have tried 
parent.function_in_parent(); 
its not working
yes both are in same domain.
for example: there are 5 .net pages page1.aspx,page2.aspx,page3.aspx,page4.aspx,page5.aspx and master.aspx
master.aspx contains the iframe with source page1.aspx, i want to call function abc() written in master.aspx from page1.aspx
