IWCGJQRegion

[etwoss]

Hi

My form is already shown.
A thread terminates and a region has to make visible:

procedure TIWFormToken.DoSimpleWaitThreadTerminate(Sender: TObject);
begin
if (FShowDialog) then
begin
IWCGJQRegion.Visible := True;
end;
end;

I can't call IWCGJQRegion.AjaxRerender() , but how can i make the region visible?

If this is being done asynchronously, then you have to call RenderRegionAsync(). You have to add IWCGAsyncRender to your uses clause.

Code: Select all

procedure TIWFormToken.DoSimpleWaitThreadTerminate(Sender: TObject);
begin
 if (FShowDialog) then
 begin
  IWCGJQRegion.Visible := True;
  RenderRegionAsync(IWCGJQRegion);  //or call it for the parent region if needed
 end;

Hi

This does not work because its not in Ajax Processing

Well said, you've to use IWTimer, checking if the thread it's terminated, and then update the browser, using any IW appliable method, including RenderRegionAsync

Hi

The IWTimer is not async right?
I did put in codesite but the event OnTimer is not executed
Another process in the same vcl tread is the cause of this, takes to much time
Thats why i uses a thread

is there no way to refresh my form if its not aSync call?

Hi

In this codesite log you see see the timer being enabled (set to 3 seconds)
However the call to GetServer takes so much processtime the OnTime event does not fire
Thats why i wanted to use a Thread and after the tread is terminated i needmake my Region visible and refresh the page.

So there is no way to just refresh the page outside an ajax call?

The OnAsyncTimer event is ajax/async yes.

no there is not no other way.

browser has to call the web app, it's a client-server technology. server doesn't call the client at any time, but using a IWTimer, has the same results, only the programming is different.

Hi

Yes the Event is async, i know, but the event is not fired at all. This meaning the class TIWTimer is not running in another thread bit in the same VCL thread as my time consuming method.

but the event is not fired at all
