Kendo file uploader to display previously uploaded files

[Kedarnath]

I am using Kendo File Upload for upload files and after uploading I convert the file to Byte array and save it on Database in the Binary data format.My requirement is I want to display the uploaded files in the uploaded area,ie the area where I upload files.(Take byte array content of files from database and the convert it into Base64 string thees section is I did)

Code:

<h2>Index</h2>

@* The file Upload code,What changes are I done this code for display files in the Uploaded area ?
<div class="box">
    <p>
        File Upload Example
    </p>
</div>
<form method="post" action='@Url.Action("Save")'>
    <div class="demo-section k-content"><h2>

         <h6>Upload Attachments</h6>

        @(Html.Kendo().Upload()
    .Name("files").
    TemplateId("fileTemplate")
    .Messages(m => m.Select("Add files here."))
    .Async(a => a
        .Save("Save", "Upload")
        .Remove("Remove", "Upload")
        .AutoUpload(false)).Events(events => events.Select("onSelect")))



        <script id="fileTemplate" type="text/x-kendo-template">
            <span class='k-progress'></span>
            <div class='file-wrapper'>
                <img class='file-icon #=addExtensionClass(files[0].extension)#' /> <!-- here im trying to bind the image -->
                @*<h4 class='file-heading file-name-heading'>Name: #=name#</h4>
                    <h4 class='file-heading file-size-heading'>Size: #=size# bytes</h4>*@

    var a = 0;
    function onSelect(e) {
        $.each(e.files, function (index, value) {
            readMultipleFiles(value);
        });
        a++;
    }

    function addExtensionClass(extension) {
        return a;
    }

Hi Lee,

The forum thread answer for the question above is placed in the following link:

• https://www.telerik.com/forums/display-files-on-the-kendo-file-upload-area#4056469

The following demo represents how to persist the successfully uploaded files in the list and display them again when the page is reloaded:

I hope this information helps.
