ClientFileUploadRemoving - How can you work out if someone is removing an invalid file

[Lachlan]

I was trying to implement some nicer client side error handling informing the user why the upload failed as the exisiting client feedback is just a red dot instead of a green dot, so I followed this example 
http://demos.telerik.com/aspnet-ajax/asyncupload/examples/validation/defaultcs.aspx

But I am now trying to work out how to hide the error message when the user clicks remove on an invalid file.

I looked at OnClientFileUploadRemoving, but that only gets triggered if a valid file is removed.

Also, is there something similar to the upload.isExtensionValid method that checks if the file size is valid? 

Thanks

Hello Lachlan,

Please review the following client side event.

Hi Peter, 

Thanks for the reply.

I am already using the:

function OnClientValidationFailed(sender, args)

I use that to display the error message, and that is being triggered fine.

What i want to know is what event is fired when a user clicks Remove  on an invalid file. So when a user clicks remove on an invalid file I would like to remove the error message. It seems that when a valid file is removed the ClientFileUploadRemoving method is triggered, but not for invalid files.

Thanks

Hello Lachlan,

Please try the following code and let me know if it helps.

<form id="form1" runat="server">
<div>
    <telerik:RadScriptManager runat="server" ID="RadScriptManager"></telerik:RadScriptManager>
    <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" AllowedFileExtensions=".jpg" OnClientFileUploadRemoving="onClientFileUploadRemoving"></telerik:RadAsyncUpload>
</div>
</form>
<script type="text/javascript">
    function onClientFileUploadRemoving(sender, args) {
        var row = args.get_row(),
            $ = $telerik.$,
            isValidFile = $(row).find(".ruUploadSuccess").length > 0;

        if (isValidFile)
            alert("You are removing Valid file");
        else
            alert("You are removing Invalid file");
    }
</script>
