Hi Edgar,

can you please describe what you want to achieve with the ShowLoader ?
Maybe a code snippet will help us to better understand your requirements.

Thanks in advance.

Best regards
Frank

Hi Frank

The code I'm using to get a showLoader displayed on a button is this one.
Not all the buttons work as you like, sometimes it appears sometimes does not appear.

this.Button.call("showLoader");
Application.Update(this);

Thanks

Hi Edgar,

is your server running on WebSocket ?
Did those hints not help you yet ? https://wisej.com/support/question/showing-a-loading-spinner#sabai-entity-content-5403

this is the scenario:
1) a user select a file with an upload component
2) the user clic a button (here is when we need to show the loader)
3) In the Click evento of the button, the server validate several things with that XML (not being used before, is valid, etc)
4a) If the XML is not valid for some reason, the loader should be hidded and a Message popup telling the user that
4b) If the XML is valid, the loader is hidded and some other elements get updates base on the XML content
private void btnValidarFactura_Click(object sender, EventArgs e)
{
//i have tried both of these and only work the way i want to, if i run the  project step by step
this.btnValidarFactura.Call(“showLoader”);
this.btnValidarFactura.ShowLoader = true;
Application.Update(this.btnValidarFactura);
 if (UploadedFileName != null)
{
if((bool)validateXML(DestinationFile))
{
//fill content from other components
this.btnValidarFactura.Call(“hideLoader”);
this.btnValidarFactura.ShowLoader = false;
}
else
{
this.btnValidarFactura.Call(“hideLoader”);
this.btnValidarFactura.ShowLoader = false;
MessageBox.Show(“The XML used is not valid.”);
}
}
else
{
this.btnValidarFactura.Call(“hideLoader”);
this.btnValidarFactura.ShowLoader = false;
  upArchivoXML.AppearanceKey = “uploadRequired”;
MessageBox.Show(“Please select an XML”);
}

From the release notes

http://setup.wisej.com/releases/notes/Wisej%20Release%20Notes-1.4.80.htm

I saw the new feature called pooling.

WJ-8809 New Feature Support automatic polling to emulate push updates without WebSocket.

Perhaps this might help you to update your client, when no WebSockets are available.
