在updatepanel中上传带文件上传控件的文件时显示进度条 [英] show progress bar while uploading file with file upload control in updatepanel

问题描述

您好b $ b

我需要知道如何在上传使用文件上传控件时显示进度条。

如果我使用按钮如

 <  触发器 >  
 <   asp：PostBackTrigger     ControlID     =  btnSave    /  >  
 <   / Triggers  >  

文件正在上传但进度条没有显示。

如果我使用的话没有postbacktrigger进度条的按钮正在显示，但是如果（FUUpload.HasFile）

变为false，那么我无法上传文件。 />


我想同时使用进度条和文件上传控件。任何1请给我一个解决方案来解决这个问题。



这是aspx代码：

 <   asp：updatepanel     id   =  UPFileupload    runat   =  server    updatemode   = 有条件的  >  
 <   contenttemplate  >  
 <   div     id   =  DivFup    runat   =  server   可见  =  false >  
 <   asp：Panel     ID   = < span class =code-keyword> Panel2    runat   =  server    >  
 <   table  >  
 <   tr  >  
 <   td     class   =  field     align   = <跨越式s =code-keyword> left >  
 <   asp：FileUpload     ID   =  FUUpload    runat   =  server   宽度  =  180％  /  >  <   br     /  >  
 <   / td  >  
 
 <   td     class   =  field    align   =  right     width   = < span class =code-keyword> 171 >  
 
 < ;   asp：按钮    CssClass   =  formbutton    ID   =  BTNImport    TabIndex   =  9    runat   =  server   文本  = 上传  
   
                                                                                                           OnClick   =  BTNImport_Click >  <   / asp：Button  >  
 
 <   / td  >  
 <   td  >  < span class =code-keyword><   / td  >  
 <   / tr  >  
 <   / table  >  
 <   / asp：Panel  > ;  
 <   / div  >  
 <   / contenttemplate  >  
 <  触发器 >  
 <   asp：PostBackTrigger     ControlID     =  BTNImport  /  >  
 <   / Triggers  >  
 
 <   / asp：updatepanel   >  

在哪里我想进行更改以使其完美运作？

Hi
I need to know how to show progress bar while uploading the using file upload control.
if i use button like

<Triggers>
                      <asp:PostBackTrigger ControlID = "btnSave" />
              </Triggers>

file was uploading but progress bar is not displaying.
if i use button without postbacktrigger progress bar is displaying but

if (FUUpload.HasFile)

becomes false so that i'm unable to upload the file.

I want to use both progressbar as well as file upload control together.can any 1 please give me a solution to come out from this issue.

Here is aspx code:

<asp:updatepanel id="UPFileupload" runat="server" updatemode="Conditional">
            <contenttemplate>
                    <div id="DivFup" runat="server" visible="false">
                        <asp:Panel ID="Panel2" runat="server" >
                                <table>
                                        <tr>
                                           <td class="field" align="left">
                                              <asp:FileUpload ID="FUUpload" runat="server" Width="180%"/><br />
                                           </td>

                                            <td class="field" align="right" width="171">

                                                <asp:Button CssClass="formbutton" ID="BTNImport" TabIndex="9" runat="server" Text="Upload"

                                                    OnClick="BTNImport_Click"></asp:Button>

                                           </td>
                     <td></td>
                                      </tr>
                                   </table>
                        </asp:Panel>
                    </div>
            </contenttemplate>
            <Triggers>
                <asp:PostBackTrigger ControlID = "BTNImport"/>
            </Triggers>

       </asp:updatepanel>

where i want to make changes to make it to work perfect?

Thanks in advance.
