I've managed to show the data on a datagrid on a form with an update button.
however, I would like the data to get updated every 5 min.
I've setup a timer with Elapsed trigger to update the gride by calling the web service and refresh the grid.
problem: my data grid does not even show up on the form when I use the timer.
code: very simple see below.
Private Timer1 As New System.Timers.Timer(10000)
Dim sales As New org.mystore.www.BookstoreSales
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.AutoReset = True
AddHandler Timer1.Elapsed, AddressOf TimerFired
End Sub
Public Sub TimerFired(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs)
UpdateGrid()
End Sub
Private Sub UpdateGrid()
StatusBar1.Refresh()
StatusBar1.Text = "Last Update: " & Now().ToShortTimeString
DataGrid1.Refresh()
DataGrid1.DataSource = sales.GetSales.Tables("BookstoreSales")
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Update.Click
Timer1.Enabled = True
StatusBar1.Text = "Timer Started"
End Sub
Problem with Web Services and Updating datagrid on windows form.

"10000" is very short time.. you can increase this time to (i.e 50000) I think your Web Services Update time is not enough to Updating Completely..

Hi,
I've changed that value all the way to 15 seconds and still didn't give me any result.
my web service is local and my test shows sub-seconds response.
Thank you for your comment.
