使用showModalDialog 父窗体变成空白

[tombrues]

DateTime now = DateTime.Now;
string s = now.ToString("yyyyMMddHHmmss ") + now.Millisecond.ToString();
string OutStr = "";
OutStr = OutStr + " <script> ";
OutStr = OutStr + " var winSettings = ' status:no; help: no; resizable: no; center:yes;dialogHeight:300px;dialogWidth:400px';";
OutStr = OutStr + " window.showModalDialog('Check_Add.aspx?time=" + s + "&PermissionID=" + PermissionID + "','', winSettings);";
OutStr = OutStr + " </script>";
RegisterClientScriptBlock("OpenSPLC", OutStr);

执行这些代码的时候，父窗体会变成空白，我看网上都说使用：RegisterClientScriptBlock来执行就可以了，但是我使用了，父窗体还是白色，是不是与版本有关系，我使用的是VS2008 C#
哪位大侠碰到这种情况麻烦告知我，我将不胜感激啊！

//可以前台調用。。也不會白屏
//把你的RegisterClientScriptBlock換成這個
//Page.RegisterStartupScript("OpenSPLC", OutStr);

使用Page.RegisterStartupScript

用个线程试试~~如果你主线程执行耗时的方法界面可能会假死掉~~

Page.RegisterClientScriptBlock("js", "<script>parent.frames('Iframe1').location.href='aaaa.aspx';</script>");
