[Tan]

To,
Problem: Unabled get Invalid file index to remove the invalid file by upload.deleteFileInputAt(i); since upload.getUploadedFiles(); only get valid file index.



<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1"
                        MultipleFileSelection="Automatic" AllowedFileExtensions=".sql" MaxFileSize="1000000"
                        OnClientValidationFailed="DeleteInvalidFiles">
</telerik:RadAsyncUpload>

function DeleteInvalidFiles() {
            var upload = $find("<%= RadAsyncUpload1.ClientID %>");
            var inputs = upload.getUploadedFiles(); //Get Valid File only

            for (i = inputs.length - 1; i >= 0; i--) {
                alert(inputs[i].value);
                if (!upload.isExtensionValid(inputs[i].value))
                    upload.deleteFileInputAt(i);
            }
}

Hello Louis,

Here is a sample function that you can use to delete all invalid files:

function deleteInvalids() {
    var upload = $find("<%= RadAsyncUpload1.ClientID %>");

    var indexes = [];
    $telerik.$(".ruUploadSuccess, .ruUploadFailure", upload.get_element()).each(function(index) {
        if ($telerik.$(this).hasClass('ruUploadFailure')) {
            indexes.push(index);
        }
    });

    while(indexes.length) {
        upload.deleteFileInputAt(indexes.pop());
    }
}

The method first goes through all uploaded files and adds the indexes of the invalid ones to an array. Then it goes through the array and deletes these files from the Upload.
 
Kind regards,
