Hi Carlos,

Please try the following Code Snippet that I have tried which works fine at my end.

ASPX:
<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions=".jpg,.png"
    OnClientValidationFailed="OnClientValidationFailed1">
</telerik:RadAsyncUpload>

JavaScript:
<script type="text/javascript">
    function OnClientValidationFailed1(sender, args) {
        $telerik.$(".ruCancel").parent().remove();
        alert("Allowed files extension are .jpg, .png");
    }
</script>

Thanks,
Shinu.

Hi Carlos,

You can try the following JavaScript to prevent resetting the control if the selected files contain an invalid file.

JavaScript:
<script type="text/javascript">
    function OnClientValidationFailed(sender, args) {
        $telerik.$(args.get_row()).css("display", "none");
        alert("Allowed files extension is .jpg, .png");
    }
</script>

Thanks,
Shinu.

Hi Carlos,

I am not sure about your requirement. I guess you don't want to show the invalid file from the selected files while uploading.The OnClientValidationFailed event will fire whenever an invalid file is selected to upload.

ASPX:
<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions=".jpg,.png"
    OnClientValidationFailed="OnClientValidationFailed1">
</telerik:RadAsyncUpload>

JavaScript:
<script type="text/javascript">
    function OnClientValidationFailed1(sender, args) {
        $telerik.$(args.get_row()).empty(); // to hide the invalid file from displaying.
        //OR
        $telerik.$(args.get_row()).css("display", "none"); //to hide the invalid file from displaying.
 
        alert("Allowed files extension are .jpg, .png"); //to show an alert if invalid file is selected to upload.
    }
</script

So the above approach will not let the user upload an invalid file and show that file name while uploading. Can you please elaborate the issue.

Thanks,
Shinu

Hi Carlos,

When you are selecting multiple files  and If the selected files contains an invalid file, that invalid file also will be listed in the controls uploaded files with a red mark which is the default behavior but internally the valid files are only uploaded to the Temporary Folder and available for upload on the server. In my code what I am doing is I am programmatically removing the invalid file name displayed along with the uploaded files list and displaying an alert. Please elaborate on what you mean by "automatically remove the invalid file". Please note when you are using RadAsyncUpload you cannot programmatically open the "Open File" window. (e.g. when RadAsyncUpload uses a SIlverlight module, the control uses the silverlight object)

Thanks,
Shinu.

Hi guys, 
same problem here i don't want to show invalid files in list, and I use the following code 
 function validationFailed(radAsyncUpload, args) {
                var $ = $telerik.$;
                var $row = $(args.get_row());
                $telerik.$(".ruCancel").parent().remove();

             }
it removes the invalid file message from list but the problem is after reaching its total file count, it hides selection button and the valid files in list is none, so how we tackle show selection button after valid files reach to total count

Hello,

You can also remove the failed validation files with jQuery as in the code below:
function validationFailed(sender, eventArgs) {
sender._updateCancelButton(eventArgs.get_row());
$telerik.$(".ruRemove", eventArgs.get_row()).click();
}

Hope this will be helpful.
