I would like to refresh a data table called Numberof carsafter clicking on the refresh button and the button will stop spinning and the textarea visualis rendered after the data is refreshed.

This is my IronPython code on my refresh action control button.


from Spotfire.Dxp.Data import DataTable

from System.Collections.Generic import List, Dictionary

from Spotfire.Dxp.Framework.ApplicationModel import NotificationService

from Spotfire.Dxp.Application.Visuals import HtmlTextArea


//notification service

notify = Application.GetService[NotificationService]();


//Tables(s) to refresh - change/add more if required

tbls = List[DataTable]()

tbls.Add(Document.Data.Tables['Number of cars'])


//After tables are refreshed, update html

def afterLoad(exception, Document=Document, notify=notify):

if not exception:


# Stop Spinner

newHtml = vis.As[HtmlTextArea]().HtmlContent

oldDiv = ''

newDiv = ''

newHtml = newHtml.Replace(oldDiv,newDiv)


# Apply change

vis.As[HtmlTextArea]().HtmlContent = newHtml;

vis.As[HtmlTextArea]().HtmlContent += " " # Force re-render




notify.AddErrorNotification("Error refreshing table(s)","Error details",str(exception))


//Refresh WAN table

Document.Data.Tables.RefreshAsync(tbls, afterLoad)



This is my HTML and JS code.

animation-name: spin;

animation-duration: 2000ms;

animation-iteration-count: 20;

animation-timing-function: linear;



@keyframes spin {

from {



to {














function refreshdt(){
