Getting problem with getting the byte[] file

[Jan Michael]

Hi, I'm expreriencing problem getting the right size of the file in byte[].
Here's my scenario: I'm uploading the file and then get the byte[] size and save it to db. When i try to upload a e.g. 4mb docx file then it goes to my Raduploadhandler.ashx, I only get the 56kb file size. Is there something wrong with my upload handler?

public class RadUploadHandler : Telerik.Windows.RadUploadHandler
{
    Dictionary<string, object> dict = new Dictionary<string, object>();

    public override void ProcessStream()
    {
        string submissionID = Request.Form["SubmissionID"];

        string submitter = Request.Form["UserAlias"];

        byte[] assetData = Convert.FromBase64String(Request.Form["RadUAG_data"]);

        this.AddReturnParam("RadUAG_associatedData", "");

        this.AddReturnParam("RadUAG_finalFileRequest", this.IsFinalFileRequest());

        this.AddReturnParam("RadUAG_success", true); // or false if something fails

        this.AddReturnParam("RadUAG_message", "");// or add an error message if it is needed

        string fileName = this.Request.Form["RadUAG_fileName"];

        string filePath = this.GetFilePath(fileName);

        this.AddReturnParam("RadUAG_fileIdent", filePath);

        this.AddReturnParam("RadUAG_fileName", fileName);

        this.AddReturnParam("RadUAG_filePath", filePath);

        if (IsFinalFileRequest())
        {
            byte[] buffer = Convert.FromBase64String(this.Request.Form["RadUAG_data"]);
            long attachmentID = SaveFileToDB(buffer, fileName, Convert.ToInt64(submissionID), submitter);
            dict.Add("AttachmentID", attachmentID);
            string associatedDataString = String.Empty;
            if (dict.Count > 0)
            {
                foreach (string key in dict.Keys)
                {
                    object value = dict[key];
                    if (value == null)
                    {
                        value = "null";
                    }

                    value = "\"" + value.ToString().Replace("\\", "\\\\") + "\"";
                    associatedDataString += "{" + String.Format(@"""Key"":""{0}"",""Value"":{1}", key, value) + "},";
                }

                associatedDataString = associatedDataString.TrimEnd(',');
            }
            this.AddReturnParam("RadUAG_associatedData", associatedDataString);
        }


    }

Hi Jan Michael,

This is because of uploading files in a small parts - chunks. When you get the uploaded information (a chunk) you need its position too. Use the code below to extract the position from the upload parameters:

long position = Convert.ToInt64(this.Request.Form[RadUploadConstants.ParamNamePosition]);

Please preview the following articles, where we are demonstrating techniques for manipulation of uploaded files:

• RadUpload ChunkTag or how to deal with uploaded files by chunk
• Process files on the server after upload
• Saving files with unique name on the server using RadUploadHandler

We hope this information will help you.

All the best,
Ivan
