Hi guys,
I have this page that needs to be populated with 2 diferent web services,
and each one takes more or less 10 seconds to finish populate his own part,
so I move on to the multi threading inside ASP.NET.
my questions is:
having a ASP.NET AJAX page and my gridView inside an atlas:UpdatePan el
control how can I update the panel so it shows the datagrid with the results
from the webservice?
Sub callDRService()
Dim dr As New drService
dr.getDRInfoFro mWebService("Jo hn", "Hansen", "Nørregade 86", "5700",
False)
gvDRWarnings.Da taSource = dr.warningTable
gvDRWarnings.Da taBind()
up.Update()
End Sub
the up control is a UpdatePanel, but at the end of the thread the panel
simple wont update :-(
any thoughts?
code for page_load and thread call
-------------------------
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArg s)
Handles Me.Load
populateDRFromW Service_Thread( )
End Sub
Public Sub populateDRFromW Service_Thread( )
Dim NewThread As Thread = New Thread(AddressO f callDRService)
NewThread.Prior ity = ThreadPriority. Lowest
NewThread.Start ()
End Sub
-------------------------

Interesting. This is probably not related to AJAX though. It probably is
related to the timing of the thread and the update call. Wrap your bind code
in a null check to make sure data is back before you call the update. That
will eliminate or confirm the timing issue.
if(dr.warningTa ble IsNotNull And dr.warningTable[0].rows.count 0) then
gvDRWarnings.Da taSource = dr.warningTable
gvDRWarnings.Da taBind()
up.Update()
end if

the problem remains...
after the page is completed, I can't update anything on it. even an
UpdatePanel :-(
what I did was wait for the 2 threads to finish and then show the page.
with MultiThreading I get the page shows up in aprox 4sec instead of the
9/12 sec before
not what I was searching in the first place - I want to present the page and
a progress bar saying that the webservice call is still running and when it
finish populate the gridview with all the info. but, I coudn't do that
yet... :-(
