未下载文件的最新进展
原标题:UpdateProgress not working with download file

更新项目没有使用下载文件。 请见以下守则,在守则中,我使用了更新小组和更新程序。

btngen 点击Im 下载前哨文件。 档案下载,但更新项目没有显示。 如果没有邮政管理处,它就没有下载,如果邮政局没有显示最新进展。 pl建议如何解决这一问题。 i 不想开一个单独的席位。

<asp:UpdateProgress ID="prgbar"  runat="server" AssociatedUpdatePanelID="pnl1" DynamicLayout="true">
  <ProgressTemplate>
    <asp:Label id="lblmsg" Text="Please wait while the report generates...." runat="server"></asp:Label>
  </ProgressTemplate>
</asp:UpdateProgress>

<asp:UpdatePanel ID="pnl1" ChildrenAsTriggers="False"  runat="server" UpdateMode="Conditional">
  <ContentTemplate>
    <asp:Button ID="btngen" Text="Generate" runat="server" onclick="btngen_Click" />
  </ContentTemplate>
  <Triggers>
    <asp:PostBackTrigger ControlID="btngen"  />
  </Triggers> 
</asp:UpdatePanel>
问题回答

利用javascript表示最新进展:使用这一javascript代码

    var updateProgress = null;

    function postbackButtonClick() {
        updateProgress = $find("<%= prgbar.ClientID %>");
        window.setTimeout("updateProgress.set_visible(true)", updateProgress.get_displayAfter());
        return true;
    }

Add OnClientClick=“return postbackButtonClick();”on You btngen Button。 希望能发挥作用。 Put the javascript after the gustmanager tag.
