Hi, 

I want to know whether the WebToolBar has a fuction, can prevent the button is duplicate submission.

Means that when click on a button, the button is not available, when all the background code are performed, then the button becomes available.

i often received user feedback that he did not respond as first time, and then click second times. I want to avoid users to submit many times.

function wtcTray_OnClick(controlId,ToolCommand) {

                switch (ToolCommand.Name.toLowerCase()) {                    

                    case 'cmdclose':                        // close this dialog
                        var dlgName = document.getElementById('hidDlgName').value;
                        //alert(dlgName);
                        parent.closeDialog(dlgName);
                        break;

                    case 'cmdsubmit':

                        //Postback to parent to create/append booking
                        // the logic is done on the server side
                        var wgTray = ISGetObject('wgTray');

                        if (wgTray.GetChangesCount() > 0) {
                            document.getElementById('hidActionAfterBatchUpdate').value = 'ToolbarSubmitBooking';
                            wgTray.AcceptAllChanges();
                        }
                        else {
                            invokeSubmitBooking();
                        }
                        
                        break;

                    default:
                        // do Nothing
                }
               
        }
