Upload file in ItemCommand does not overwrite existing file

[Alexander]

Hi,
I am using an RadAsyncUpload inside my grid, to upload a single file. When in edit mode, the existing file is supposed to be overwritten. But this is not the case. I have tried with several different ways to create the file (my example here is the last one) - I have also tried using File.WriteAllBytes. This is my code:
In create mode, the file is created perfectly...

Control asyncUpload1 = editableItem.EditManager.GetColumnEditor("FileNameWithExtension").ContainerControl.FindControl("AsyncUpload1");

if (asyncUpload1 != null && asyncUpload1 is RadAsyncUpload)

{

    if (((RadAsyncUpload)asyncUpload1).UploadedFiles.Count > 0)

    {

        UploadedFile uploadedFile = ((RadAsyncUpload)asyncUpload1).UploadedFiles[0];

        if (letterTemplate.FileNameWithExtension != uploadedFile.FileName && letterTemplate.FileNameWithExtension != null)

        {

            File.Delete(GetTemplatePath(letterTemplate.MunicipalityCode, letterTemplate.FileNameWithExtension));

        }

 

        letterTemplate.FileNameWithExtension = uploadedFile.FileName;

 

        byte[] buffer = new byte[uploadedFile.InputStream.Length + 1];

        uploadedFile.InputStream.Read(buffer, 0, buffer.Length);

 

        CreateDirectoryIfNotExistent(Server.MapPath(string.Format(TEMPLATE_PATH, letterTemplate.MunicipalityCode)));

        using (FileStream stream = new FileStream(GetTemplatePath(letterTemplate.MunicipalityCode, letterTemplate.FileNameWithExtension), FileMode.Create))

        {

            stream.Write(buffer, 0, buffer.Length);

        }

    }

    else if (e.CommandName == CMD_CREATE)

    {

        Label error = (Label)editableItem.EditManager.GetColumnEditor("FileNameWithExtension").ContainerControl.FindControl("lblError");

        error.Text = "Angiv en Word skabelon-fil.";

        return;

    }

}
