我有一个订单输入页面，可能需要一段时间来处理，用户认为浏览器已经冻结并关闭它。这是一个弹出式浏览器，单击cmdAdd按钮时，文本框中的项目将写入数据库，子窗口将关闭，父窗口将刷新以查看更改。目前运行良好。
我添加了一个AJAX UpdateProgress来给用户一些反馈，但是现在cmdAdd浏览器不会关闭，父浏览器也不会更新。进度指示器会显示，数据库也会更新，但就是这样。有什么想法吗？
注意：UpdateProgress指示器在站点的其他地方使用，没有问题，只是我在弹出的子窗口中使用它。cmdAdd_click在没有updateProgress控件的情况下正常工作（子控件关闭，父控件刷新）

命令添加单击：
protected void cmdAdd_Click(object sender, EventArgs e)
{
string qty = null;
string itemCode = null;
int orderID = Convert.ToInt32((Session["OrderID"]));
int seqNum = 0;
int orderSeqNum = 0;
string description = null;
JWebUtils.priceType pricing = default(JWebUtils.priceType);
double price = 0;
string type = null;
ArrayList sqlParams = new ArrayList();
JWebDB db = new JWebDB();
System.Text.StringBuilder script = new System.Text.StringBuilder();
int discount = 0;
string strDisc = null;
JWebUtils jweb = new JWebUtils();
<< CODE TO UPDATE DB OMITTED FOR BEREVITY >>
script.Append("<script language=\"javascript\">");
script.Append("window.opener.document.forms[0].submit();self.close();");
script.Append("</script>");
Session["IsPopup"] = true;
ClientScript.RegisterStartupScript(this.GetType(), "XYZ", script.ToString());
}
最佳答案
首先，您应该在页面中添加一个ScriptManager，然后应该使用：
ScriptManager.RegisterStartupScript(...
