private void Button2_Click(object sender, System.EventArgs e)
{
RegisterStartupScript( "key ", " <script> window.returnValue=document.all( 'upFile ').value;window.opener=null;window.close(this); </script> ");
}
父窗口如何获得返回的值呢?

父窗口：
function OpenWindow(Url){
}
------解决方案--------------------------------------------------------
var r = window.showModelDialog(...);
alert(r);
