Question

Ultimately, what I would like to do is upload files directly into the database, so I updated this question with the code I’m using to write to the database.

I am developing a module in DotNetNuke using Telerik controls. I need to upload files to the server in the user interface, so I am using the RadUpload control and the RadProgressArea/RadProgressManager.

Here is my ASP:

<telerik:RadUpload ID="RadUpload1" runat="server" ControlObjectsVisibility="CheckBoxes, RemoveButtons, ClearButtons"
                AllowedFileExtensions=".doc,.docx,.pdf,.tiff,.gif,.jpg,.jpeg,.xls,.xlsx" MaxFileInputsCount="2"
                MaxFileSize="10000000" InitialFileInputsCount="2">
            </telerik:RadUpload>
            <br />
            <asp:Button ID="UploadButton" runat="server" Text="Upload File(s)" />
            <telerik:RadProgressArea ID="RadProgressArea1" runat="server" ProgressIndicators="TotalProgressBar, TotalProgress, RequestSize, FilesCountBar, FilesCount, SelectedFilesCount, CurrentFileName, TimeElapsed, TimeEstimated, TransferSpeed">
            </telerik:RadProgressArea>
            <br />
            <telerik:RadProgressManager ID="RadProgressManager1" Runat="server" />

And here is my VB:

   Protected Sub UploadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UploadButton.Click
    If RadUpload1.UploadedFiles.Count > 0 Then
        System.Threading.Thread.Sleep(3000)
    End If
    For Each file As UploadedFile In RadUpload1.UploadedFiles
        Dim bytes(file.ContentLength - 1) As Byte
        file.InputStream.Read(bytes, 0, file.ContentLength)
        Try
            ' Create the sales order in the database on page load so that the salesorderid is unique
            Dim connection As String = ConfigurationManager.ConnectionStrings("SiteSqlServer").ConnectionString
            Dim con As New SqlConnection(connection)
            Dim cmd As New SqlCommand("INSERT INTO TTC_UploadedFiles ([Name], [Size], [Content]) VALUES (?, ?, ?)", con)
            cmd.Parameters.AddWithValue("@Name", file.GetName())
            cmd.Parameters.AddWithValue("@Size", bytes.Length)
            cmd.Parameters.AddWithValue("@Content", bytes)
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
        Catch ex As Exception
            Label1.Text = ex.ToString
        End Try
    Next
End Sub

When I hit the button, it does a postback to the page, but the files do not get uploaded. I tried using the autoupload functions and specifying pysical and virtual paths but that didn’t work. I did it exactly like they said. I manually registered the controls in my web.config, then removed them and used the auto-register feature to re-register thinking maybe I did something wrong, but I’m still at a loss.

Here’s where I spent the last couple hours:
[Upload Overview][3]
[Files are not uploaded][4]

Can someone help me get this upload control and progress indicator working?

This is not direct related to your question. I use AsyncUpload, which can select muliple files at once, and upload files to database. The following is the sample code. I strip out the validation codes for the sake of simplicity.

<!-- ASPX page -->
<telerik:RadProgressManager runat="server" ID="RadProgressManager1" />
<telerik:RadAsyncUpload runat="server" ID="AsyncUpload1" InputSize="40" MaxFileSize="10485760">
</telerik:RadAsyncUpload>
<telerik:RadProgressArea runat="server" ID="RadProgressArea1">
</telerik:RadProgressArea>

// Code behind
ImageManager.InsertImage(AsyncUpload1.UploadedFiles);

// In business logic
public static void InsertImage(UploadedFileCollection uploadedFileCollection)
{   
   foreach (UploadedFile uploadedFile in uploadedFileCollection)
   {  
      string filename = uploadedFile.GetName();   

      // Process the image into byte array
      Stream imgStream = uploadedFile.InputStream;
      int imgLen = uploadedFile.ContentLength;
      byte[] imgBinaryData = new byte[imgLen]; 
      imgStream.Read(imgBinaryData, 0, imgLen);

      // Get width and height
      Image originalimg = Image.FromStream(imgStream);

      // Get rid of white spaces
      filename = string.Concat(Regex.Replace(Path.GetFileNameWithoutExtension(filename),
         "[^\\w-]", string.Empty), Path.GetExtension(filename));

      // Now you get - 
      // imgLen
      // filename
      // imgBinaryData
      // originalimg.Height;
      // originalimg.Width;
   }  
}

Edit: In web.config, depending on what IIS you are using.
