    Get File Stream similar to HTTP Posted File.

    Reply Quote

    Hi all , 

     

    I am using CuteWebUI file uploader control . It's markup is

     

    <table>
        <tr>
            <td style="width: 50%">
               <CuteWebUI:UploadAttachments runat="server" MultipleFilesUpload="true" ManualStartUpload="true"  ID="Uploader1" InsertText="Browse Files (Max 1M)"  >
            </CuteWebUI:UploadAttachments>
            </td>


             <td style="width: 50%">
                  <asp:Button ID="btnUploadFiles" Text="Create Scripts ....." runat="server" />
            </td>   
        
        </tr>   
       </table>   

     

    My requirement is given below .

     

    1) User should be able  to select multiple files. 

    2) When btnUploadFiles is clicked , file streams of selected files should be read in code behind , similar to HTTPPostedFileCollection that we have for asp.net upload control. 

    3) Further business logic after reading each of the  file content .  

     

    Can you please guide me if it is possible?

     

    Thanks
