How can I change ASP.NETAJAX ModalPopupExtender z-index. By default it is 100001. Thanks.

推荐答案

我使用此功能：

  function ShowModalPopup(modalPopupId, zIndex) {

    try {
      if (modalPopupId == null) throw new Error(0, 'Incorrect value of param modalPopupId!');

      var modalPopupBehavior = $find(modalPopupId);
      if (modalPopupBehavior == null) throw new Error(0, 'Not found modal popup ' + modalPopupId + '!');

      zIndex = typeof (zIndex) != 'undefined' ? zIndex : null;

      if (zIndex != null) {
        modalPopupBehavior._backgroundElement.style.zIndex = zIndex;
        modalPopupBehavior._foregroundElement.style.zIndex = zIndex + 1;
      }

      modalPopupBehavior.show();
    }
    catch (ex) {
      alert('Exception in ShowModalPopup: ' + ex.message);
    }
  }

和它的呼叫：

  ShowModalPopup('<%= modalpopup.ClientID %>', 20001);
