showModalDialog Problem in PostBack in ASP
I would like to have a lookup form in my ASP app. So I use client script to popup a Lookup aspx page and the page will display a grid and let use to select. and the code to pop the form is listed below
retval = window.showModalDialog( "ALookup.aspx", window);
But I face a problem, when I click a link button in my datagrid and the error message is like that
Object Required :-
javascript:__doPostBack('dgLookup$_ctl3$_ctl0','')
Does anymore can help or give me a hint on this ??
Thank you...
