Hide retry button in kendo UI upload on error


Share with WhatsApp


This post covers information about how you can hide retry or refresh button which comes when any file upload fails or you throw an error after validating the uploaded file.

In one of my implementation I supposed to hide this "Retry" button and force user to reselect the correct files if any upload fails along with the error message for each failed upload.

Let's see how you can achieve this kind of functionaliy for Kendo UI Upload.

Suppose you have Kendo UI Upload defined like below.

@(Html.Kendo().Upload()
    .Name("fileUploader")
           .Async(a => a
           .Save("UploadActionName", "ControllerName")
           .AutoUpload(true)
           .Batch(false)
    )
   .Events(events => events.Error("onErrorUplaod"))
   .Multiple(true)
   .ShowFileList(true)
   .Messages(m => m.Select("Select file(s)"))


Then you need to handle Error event like below

function onErrorUplaod(e) {          
    var err = e.XMLHttpRequest.responseText;          
    $(".k-retry").parent().hide();
    $("span[title='" + e.files[0].name + "']").html(e.files[0].name + "<br/><p style='overflow-x:auto;overflow-y:hidden'>" + err + "</p>");
}

That's it. With above code retry button will get hidden and also the error message will get displayed below each failed file. I have not handled all validation so you may require to add some code to the above code.

Hope you have benefitted with above code. Let me know in comment section if you are facing any issues with above code. Thanks.
