I would be nice to gain more control over radasyncupload's upload behavior when using database as storage for uploaded files.

Consider this use case. You have file management web-app that uses SQL database as storage for uploaded files. In SQL database you use Filestream enabled table to store the uploaded file data. You like to allow your app users to upload multiple big files > 100 Mt at once. And you have limited disc space on your web server hosting your app. So you don't want to buffer those uploaded files on your web server in any point of the upload process.

To be able to do so radasyncupload needs to be able to stream uploaded files to the SQL database as straight as possible. Chunk by chunk. 

radasyncupload already has feature that allows you to use your own generic handler to handle some of the upload process. It just needs expose some of those events that happens before process-event (maybe ProcessRequest?). So developer can start handling the HttpPostedFile's InputStream at the begining of the upload and stream it directly to the database. Like one can do with the regular upload controls like so:

Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

	Dim hpf As HttpPostedFile
	
	For i = 0 To context.Request.Files.Count - 1
	
		hpf = context.Request.Files.Item(i)
		
		...
		Using Command As SqlCommand = New SqlCommand(String.Concat("INSERT INTO Dokuments(DokumData...) values (@DokumData...)"), connection)
		'Other params

		Command.Parameters.Add("@DokumData", SqlDbType.Binary, -1).Value = hpf.InputStream
		connection.Open()
		Command.ExecuteScalar()
		connection.Close()
		
	Next

End Sub

Documentation says Firefox should be ok with LastModifiedDate, but it's not.  It's consistently being set to 1/1/0001 12:00:00 AM, which is not useful.

Happens in any RadAsyncUpload example if you look at the value for LastModifiedDate in the AsyncUploadedFile objects.

Works fine in Chrome, Edge.  Fails in Firefox for Mac or Windows.

After the update from version 2018.2.710 to 2019.1.2015 the files bigger than 2 MB are cut off (up to 2 MB) and broken during the upload.

When the ChunkSize of RadAsyncUpload is set the files are not fully uploaded. A sample excel file to reproduce the issue is attached to this reply.
Temporary fix:
Remove the ChunkSize setting of the AsyncUploade:

        <telerik:RadAsyncUpload ID="UploadFile" runat="server" MultipleFileSelection="Automatic"
            OverwriteExistingFiles="true" ReadOnlyFileInputs="true" InputSize="45" EnableViewState="true" TargetFolder="~/UploadedFiles">
        </telerik:RadAsyncUpload>

Steps to reproduce:

1. Run the following configuration and upload the attached to this item file
        <telerik:RadAsyncUpload ID="UploadFile" ClientIDMode="AutoID" runat="server" MultipleFileSelection="Automatic"
            OverwriteExistingFiles="true" ReadOnlyFileInputs="true" ChunkSize="3145728" InputSize="45" EnableViewState="true" TargetFolder="~/UploadedFiles">
        </telerik:RadAsyncUpload>
        <telerik:RadButton runat="server" Text="Upload"></telerik:RadButton>


Expected: An 11MB file is uploaded
Actual: An 8MB file is uploaded (the last chunk part is missing)

We have created a KB article where a possible approach to achieve image resizing before the upload is suggested. You can find it at https://www.telerik.com/support/kb/aspnet-ajax/upload-(async)/details/resize-images-client-side-with-html5-before-uploading-with-radasyncupload

The article describes a straightforward way on how to change the uploaded image dimensions. You can further improve and modify the logic in the _uploadFile function to allow the user to define the new dimensions or use a tool to allow the users to modify the image.

The drop zone and the custom drop zones are shifted below their expected positions in Edge 40.

Check the following video demonstration https://www.screencast.com/t/2m8SxR8jbwb.

The problem is reproducible in the http://demos.telerik.com/aspnet-ajax/asyncupload/examples/draganddrop/defaultcs.aspx demo.

When upload larger files the connection may dropped during the file uploading. In result of this the selected file will not be uploaded successfully and the user will have to start the uploading from the beginning. This operation can be very annoyng when connection is slow. 

The suggested features aims to allow resuming, when the failed file is selected again. The uploading should continue automatically from there it stopped.

Workaround: 

function encodeRowContent() {
    var asyncUpload = $find('<%= RadAsync_FileUpload.ClientID%>');
    var $ = $telerik.$;
    asyncUpload._updateRowContent = function (row, inputValue) {
        var $progress,
            $content = $("<span class='ruUploadProgress'>" + $telerik.htmlEncode(this._getFileName(inputValue)) + "</span>");

        $(row).removeClass("ruSelectWrap")
                .addClass("ruFileLI ruUploading")
                .prepend("<span class='radIcon'></span>");

        if (this._isManualUpload())
            $content.addClass("ruUploadOnHold");

        if (this._enableInlineProgress) {
            $progress = $('<span class="ruFileProgressWrap"><span class="ruFileProgress"></span></span>');
            $content.append($progress);
        }

        $('.ruFakeInput, .ruBrowse', row).remove();
        $(".ruFileWrap", row).append($content); // Replace fake input
    }
}

Sys.Application.add_load(encodeRowContent);

Currently the AsyncUpload saves the chunks in the Temporary folder using the original name of the file, the Process method of the Custom handler. When the Temporary folder name is very long, it can hit the Windows path length limitation of 260 symbols.

Why not add a "basic mode" to radasyncupload? that saves the selected file(s) in the target folder as soon as the upload is complete without the need for an extra postback?

Or facilitate a postback through a popup "upload complete" with an ok button?

And a little feedback in general on the documentation nearly all the examples have all the bells and whistles active, which makes them hard to read for programmers with little experience like me. 

Why not have every control with a absolutely minimalistic example that only shows the core functionality?

The RadAsyncUpload control is used on forms with other controls, and sometimes we need to validate the control, that is require that the user uploads a file before the form can be submitted.  We have to use a Customvalidator and check the controls client-side properties to see if it has a file.  But if you set the ControltoValidate property an exception occurs.  
Please support this property so that a radAsyncUpload control can be associated with an ASP.Net validator.

Hi Telerik Team,
is it possible to implement the feature into the uploadmodule control , that you can open the uploaded files per Double-Click.
We want to use the control to create offers and we want to give the users the option to upload files - that works wonderful.
But the following editors of the offers don`t have the chance to open the "attached" files.

Thank you very much.
Best Regards,

Jan Brandenburger
