    Hello,

    I am using the following code in order to give user the ability to cancel uploading a file, while giving the developer the ability to do more actions:

            $telerik.$(".ruCancel", area.get_element()).click 
            ( 
                function(e)  
                { 
                    return CancelUpload(); 
                } 
            );   
     
     
    //---------------------- 
     
        function CancelUpload() 
        { 
            area.cancelRequest(); 
            alert('canceled');
            return false;    
        }        


    what happens is that the alert is executed, which leads to the assumption that the cancelReuest was also executed, but the browser status bar still shows that the file is under upload !!!!

    this only happens when using Chrome.

    Hello Basel Nimer,

    The CancelRequest functionality does not work under Chrome and Safari. This is due to a WebKit restriction that no JavaScript can be executed after form submission. This problem is one of the limitations of RadProgressArea is enlisted here.

    Hello Basel Nimer,

    You can use the following code in order to hide the cancel button under Safari and Chrome:

    <script type="text/jscript">
            function clientClick() {
                function callBack() {
                    var area = $find("RadProgressArea1");
                    $telerik.$(".ruCancel", area.get_element()).hide();           
                }
     
                if ($telerik.isSafari) {
                    setTimeout(callBack, 1000);
                }
            }
             
         
        </script>
     
        <telerik:RadProgressManager runat="server" ID="RadProgressManager1" />
        <telerik:RadUpload runat="server" ID="RadUpload1" AllowedFileExtensions=".jpeg, .jpg">
        </telerik:RadUpload>
        <telerik:RadProgressArea runat="server" ID="RadProgressArea1" DisplayCancelButton="true">
        </telerik:RadProgressArea>
        <asp:Button runat="server" ID="UploadButton" Text="Postback"  OnClientClick="clientClick();" />

    The clientClick function is invoked when one click on the upload button.
