I have to show model popup extender using jquery. popup is in Master page.
That JS i am registering using RegisterClientScriptBlock.
In JS page using $find(Behaviourid) and making it show but it is giving error null object.
if i am using only $('') then it is neither giving error nor showing popup.
From Codebehind its working fine but i need to show it through JS.
Thanks in Advance...
