[cielo valdoz]

Hi,

Im getting data from sql database using linq but it takes time before it completes the execution. I want to have a loading animation while calling the wcf service. Pls help.

Thanks

Hi Cielo,

You may want to check out this post on my blog, which talks about displaying an ActivityControl every time a time-consuming operation is in progress.

You may also want to download the source code for my Task-It (Silverlight 4) application so you can step through what I am talking about in the blog.

Hi,

Thanks for the reply. I can now display animations using storyboard while calling the service. I used same loading animation on Silverlight startup, but i want to have a percentage (%) value to determine the remaining percent.

    Private Sub PopulateOptions()

        'chartLayout.Visibility = Visibility.Collapsed
        'RadProgressBar1.Visibility = Visibility.Visible
        LoadingPopUp.IsOpen = True
        Loading.Visibility = Visibility.Visible

        Me.timer = New System.Windows.Threading.DispatcherTimer()
        Me.timer.Interval = TimeSpan.FromMilliseconds(10)
        AddHandler Me.timer.Tick, New EventHandler(AddressOf Me.timer_Tick)
        Me.timer.Start()

        Dim mService As DashboardService.DashboardClient = New DashboardService.DashboardClient()
        AddHandler mService.GetCategoryGroupCompleted, AddressOf webService_GetCategoryGroupCompleted
        AddHandler mService.GetCategoryCompleted, AddressOf webService_GetCategoryCompleted
        AddHandler mService.GetTerminalCompleted, AddressOf webService_GetTerminalCompleted
        AddHandler mService.GetSalesPersonCompleted, AddressOf webService_GetSalesPersonCompleted

        mService.GetCategoryGroupAsync()
        mService.GetCategoryAsync()
        mService.GetTerminalAsync()
        mService.GetSalesPersonAsync()

    End Sub

    Private Sub webService_GetSalesPersonCompleted(ByVal sender As Object, ByVal e As DashboardService.GetSalesPersonCompletedEventArgs) Handles webService.GetSalesPersonCompleted
        cmbSalesItemSalesPerson.ItemsSource = e.Result
        cmbSalesItemSalesPerson.SelectedValuePath = "Code"
        cmbSalesItemSalesPerson.DisplayMemberPath = "Name"

        cmbTotalSalesSalesPerson.ItemsSource = e.Result
        cmbTotalSalesSalesPerson.SelectedValuePath = "Code"
        cmbTotalSalesSalesPerson.DisplayMemberPath = "Name"

        timer.Stop()
        chartLayout.Visibility = Visibility.Visible
        If chkSalesItemOption.IsChecked Then ChartSalesItem.Visibility = Windows.Visibility.Visible
        If chkTotalSalesOption.IsChecked Then ChartTotalSales.Visibility = Windows.Visibility.Visible

        LoadingPopUp.IsOpen = False
        Loading.Visibility = Visibility.Collapsed

    End Sub

    Private Sub timer_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
        'LoadingText.Text = stepSize + Me.stepSize & "%"
        'stepSize += Me.stepSize '+ "%"
    End Sub

Thanks

Hi Cielo,

 WCF operations don't really have a way to report on their progress. Please check out the following link: http://forums.silverlight.net/forums/p/169137/381135.aspx
