add two types of validation check to radbutton

[Chap]

Hello,
I have a two radtextbox, rad upload , radbutton and a seperate rad grid.
I already added validation to radtextboxes and rad upload using asp req field validator and custom field validator.
And I also wanted to add another validation to rad upload button which checks the value in radtextbox1 if exists in the radgrid column "TemplateName". if this condition get true I want a popup message "This tmp exist, are you want to replace it?" if user click ok. it will call the method and if not do nothing. Otherwise do normal scenario. Can I do this? if can, how?

Here is the code snippts,

<div style="margin-left: 12px;">
                <table>
                <tr>
                <td></td>

Javascript using

function validateRadUpload(source, e) {
            e.IsValid = false;
            var upload = $find("<%= RadUpload1.ClientID %>");
            var inputs = upload.getFileInputs();
            for (var i = 0; i < inputs.length; i++) {
                //check for empty string or invalid extension
                if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {
                    e.IsValid = true;
                    break;
                }
            }
        }

Hi Chap,

 
I have tested the following code and it worked as expected at my side:

<script type="text/javascript">
            function OnClientClicking(sender, args) {
                args.set_cancel(!window.confirm("Are you sure you want to overwrite this template?"));
            }

        </script>
       <telerik:RadUpload ID="RadUpload1" runat="server" AllowedFileExtensions=".doc,.docx"
                                ControlObjectsVisibility="None" MaxFileInputsCount="1" OverwriteExistingFiles="true"
                                ValidationGroup="SubmitButton" Width="240px">
                            </telerik:RadUpload>
         <telerik:RadProgressArea ID="RadProgressArea1" runat="server"  >
                                </telerik:RadProgressArea>
                 <telerik:RadProgressManager ID="RadProgressManager1" runat="server" />
        <telerik:RadButton runat="server" ID="RB1" OnClientClicking="OnClientClicking">

        </telerik:RadButton>

Please review it and let me know what else should I add to this code in order to reproduce the unusual behavior you are experiencing.

thanks, it works well with this OnClientClicking="OnClientClicking"
