Response.redirect from the code behind

[thomson]

Hi all,
I do have a javascript which opens a new form on click of a
button
which i call it like

winOpen=window.open('MainForm.aspx?module='+
arg_value+''ARModule','toolbar=no status=no top=0 left=0
resizable=yes');

Instead of opening another window, i made the button as a server
control and in the click event i wrote

Response.Redirect("MainForm.aspx?module=50");


this method redirects the page but the page which has two frames does
not get displayed


Help me out

thanks in advance
