need to understand if report completed.

[aykut]

In report class, I make some calculations. like:

my variable is declared like:

Protected  runningPageValue As Double

Private Sub pageFooter_ItemDataBound(sender As Object, e As EventArgs) Handles pageFooter.ItemDataBound

    Dim processingPageFooter = TryCast(sender, Telerik.Reporting.Processing.PageSection)
    Dim processingPageExecTextBox = TryCast(processingPageFooter.ChildElements.Find("txtSayfaToplami", True)(0), Telerik.Reporting.Processing.TextBox)
    runningPageValue += Convert.ToDouble(processingPageExecTextBox.Value)

    Dim processingRunningPageExecTextBox = TryCast(processingPageFooter.ChildElements.Find("TextBox3", True)(0), Telerik.Reporting.Processing.TextBox)
    processingRunningPageExecTextBox.Value = runningPageValue

End Sub

as a result when I refresh report, export report to pdf, print report etc.. all report events run again (naturally) but my variable never sets to zero. I tried all disposed events but could not succeeded.

I need to understand if report ends, then set runningPageValue=0

how a report component does not have completed event ? how should I use variables here ? please help. everytime report prints, refreshes or esports, number are groving, bigger and bigger.

I had the same problem - and posted a few days ago
the best solution I found is to handle the UpdateUI event of the ReportViewer

  private void crViewer_UpdateUI(object sender, EventArgs e)
  {
      var viewer = sender as Telerik.ReportViewer.WinForms.ReportViewer;
      switch (viewer.ProcessingState)
     {
//        case Telerik.ReportViewer.WinForms.ProcessingState.NoReport:
//            MessageBox.Show("NoReport");
//            break;
//        case Telerik.ReportViewer.WinForms.ProcessingState.Partial:
//            MessageBox.Show("Partial");
//            break;
          case Telerik.ReportViewer.WinForms.ProcessingState.Processing:
//            MessageBox.Show("Processing");
              break;
          case Telerik.ReportViewer.WinForms.ProcessingState.Success:
//            MessageBox.Show("Success");
              this.IdleStage();
              break;
//        case Telerik.ReportViewer.WinForms.ProcessingState.Failure:
//            MessageBox.Show("Failure");
//            break;
     }
 }

Telerik processes its reports asynchronously

I had originally had the report trigger an event which the calling program caught - but Telerik techs said that interfered with ViewState

thanks. I solved problem by checking page number in ItemDataBound event. if it 1, I reset the variables. even getting page number was nightmare.  But I've to say,  me and all our s/w development team really disappointed about telerik reporting component. if I were developing something like that and my employees would show me a report component like this, I would say "go look other components in the market first, then we talk".

I have to disagree, Telerik's reporting solution has been a breeze since I migrated from crystal, evaluated DevX prior making final decision on Telerik. You just try one of these and then come talk to me about disappointment ...
I'm not sure what exactly you poke, but have you tried doing this without coding, there is a RunningValue function that can be used directly in expression with specific scope: http://www.telerik.com/help/reporting/expressions-data-functions.html.

I'm with you Massimiliano

the Reporting itself is a little awkward, what with having to create a separate class library and all, then pasting the production connection string into the data source before recompliing the calling program

all that agita is more than made up when it comes to deployment - and the nightmare that is Crystal versions
