Hi,
I am getting very weird problem. I have a model pop extender and I am making user to fill fields in it. So if user misses some field/text box I wanted a message to be generated accordingly in the message box. It happened succesfully however when i Click Ok in the message box than whole of the page gets refreshed and hides the pop up. Than I have to go back again and repeat the process. M i missing something ? Please help. Here is my code for message Box:

private void MessageBox(string msg)
  {
      // define a javascript alertbox containing
      // the string passed in as argument

      // create a new label
      Label lbl = new Label();

      // add the javascript to fire an alertbox to the label and
      // add the string argument passed to the subroutine as the
      // message payload for the alertbox
      lbl.Text = "<script language='javascript'>" + Environment.NewLine + "window.alert('" + msg + "')</script>";

      // add the label to the page to display the alertbox
      Page.Controls.Add(lbl);
  }

推荐答案

我会说不用添加此标签，而只需设置modalpopup扩展程序标签值并显示 modelpopup扩展程序使用show()方法，确保将onClientClick = return设置为false或将该按钮设置为modalpopup扩展程序的okcontrolid

否则，您也可以注册启动脚本，因为在页面中使用Ajax时，您需要使用scriptmanager.registerstartupscript，请参考

Hi,

I would say instead of adding this label you just set the modalpopup extender label value and show modelpopup extender using the show() method, make sure to set onClientClick=return false or set that button as okcontrolid for modalpopup extendar

Or else you can register startup script also, as you are using ajax in your page you need to user scriptmanager.registerstartupscript, pls refer ScriptManager.RegisterStartupScript

此弹出消息框应显示在Page_ Unload 中，以使其正常工作.
