Radconfirm instead of args.set_cancel(!confirm('Delete all selected customers?'))

[GlenB]

I would like to replace args.set_cancel(!confirm('Delete all selected customers?')) as in the example located at http://demos.telerik.com/aspnet-ajax/toolbar/examples/applicationscenarios/gridcommanditem/defaultcs.aspx?product=toolbar with a radconfirm window. I have spent hours trying different methods to achieve this and have run out of ideas.

I am using a radtoolbar as a radgrid commanditem and my code is as follows:

Javascript:

            function onToolBarClientButtonClicking(sender, args) {
                var button = args.get_item();
                if (button.get_commandName() == "DeleteSelected") {
                    if (document.getElementById('hdn_Hosp').value) {
                    args.set_cancel(!confirm('Delete ' + document.getElementById('hdn_Hosp').value + '?'));
                    }
                }
            }

ASPX:

    <form id="form1" runat="server">
    <asp:HiddenField ID="hdn_Hosp" runat="server" />
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">

                    </td>
                </tr>
                <tr>
                    <td align="center">
                        <asp:Button ID="btnCancel" runat="server" Text="Cancel" OnClientClick="closeWindow();" UseSubmitBehavior="false" Width="70px" />
                    </td>
                </tr>
            </table>
        </asp:Panel>
    </div>
    </form>

(there is some other javascript there, but nothing to do with the delete command).

I haven't posted what I've tried as i've tried 15 different ways to replace the delete method with a radconfirm, so thought it would be better to post what I currently have (which works).

If someone can assist with how to implement a radconfirm when using a radtoolbar in a radgrid I would be very grateful.

Thanks Fiko. My solution ended up being here: http://www.telerik.com/community/forums/aspnet-ajax/grid/radconfirm-to-delete-records.aspx

The code library you mentioned will be of great help for the confirmations I wanted to implement on page closures though - thanks.
