How to upload multiple files and view the uploaded files?

Question

I wanted to view the uploaded files. I am uploading 2 PDF's out of which only 1 PDF is showing when I click on uploaded(view) link. The issue is only viewing the uploaded file. I am uploading the 2 PDF files in agreement folder where I can see the uploaded files. But when I click on uploaded(view) link, it displays only 1 PDF file.

Below is my code.

Page load:

ViewState["filename"] = agremtname;
if (dt.Rows[0]["agreement"].ToString() == "0")
{
    rbno.Checked = true;
    FileUpload1.Enabled = false;
}
else
{
    rbyes.Checked = true;
    lbluploadmsg.Text = "Uploaded(View)";
    agreefile.Attributes["href"] = "~/Agreements/"+ agremtname;             
}

Source code:

<tr><td class="style11" >Reply recieved date<br/>   <asp:TextBox ID="txtrecdate" Width="207"  class="datepicker" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator10"
            ValidationGroup="valBtoA" ControlToValidate="txtrecdate" runat="server" ForeColor="red" ErrorMessage="reply date!!"></asp:RequiredFieldValidator>
    </td>

    <td class="style3">
    Agreement
        <asp:RadioButton ID="rbyes" GroupName="agree"  AutoPostBack="true" OnCheckedChanged="enablefileuploader" runat="server" />
                  Yes
        <asp:RadioButton ID="rbno" GroupName="agree" AutoPostBack="true" OnCheckedChanged="disablefileuploader"  runat="server" />
                  No&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
           <a id="agreefile" target="_blank" runat="server"><asp:Label ID="lbluploadmsg" ForeColor="blue" runat="server" ></asp:Label>
          </a>
      <br/>    
    </td>
    </tr>

      <tr>


    <td class="style10"> Agreement<br/> 
        <%--<asp:TextBox ID="txtagreement" runat="server" Width="119px"></asp:TextBox>--%>
        <asp:FileUpload ID="FileUpload1" runat="server" accept=".pdf,.PDF" AllowMultiple="true" />
       &nbsp;&nbsp; <asp:Label ID="lblfileupmsg" runat="server" ForeColor="red"></asp:Label>
        </td>
    <td class="style12">
    Comment2<br/> 
      <asp:TextBox ID="txtcomment2" TextMode="MultiLine" Width="207" runat="server"></asp:TextBox>       
    </td>
    </tr>

Update button code:

if (rbyes.Checked)
{
     if (FileUpload1.HasFile)
     {

         agreement = "1";
         filename = Path.GetFileName(FileUpload1.FileName);
         string fileLocation = Server.MapPath("~/Agreements/" + filename);
         FileUpload1.SaveAs(fileLocation);

     }
     else {
         filename = ViewState["filename"].ToString();
         if (filename == "")
         {
             lblfileupmsg.Text = "Please Upload Agreement file!!!";
             return;
         }
         agreement = "1";
     }

 }
 else if (rbno.Checked)
 {
     filename = "";
     agreement = "0";
 }

I know that to view multiple files, I have to use a loop in page load but I am not getting how to implement it.

Answer 1

You have to take count variable to count the number of files, also you have to save multiple file name in a variable and seperate them using , through logic first.

int Count = 0;

Inside for each loop

     agreement = "1";
     filename = Path.GetFileName(FileUpload1.FileName);
     string fileLocation = Server.MapPath("~/Agreements/" + filename);
     FileUpload1.SaveAs(fileLocation);
     count++
  if (count > 1)
            {
               string multiplefilename  += "," + filename;
            }
            else if (count == 1)
            {
                string multiplefilename = filename;
            }

While Retrieving files to get view

First split the multiplefilename with ,and save the result in array of string and

string[] Array = recc.MultipleFile.Split(',');

retrieve files then using for loop.
