I am currently running a report that takes several minutes to complete. We have a blind user working with this application and I need to notify him when the report rendering has completed. There is a RenderingBegin event, but is there any kind of RenderingComplete event or equivalent? I plan to use this event to trigger a message box to notify the user when the report rendering has completed.

Thank you

Exception:'The 'IObjectScope' is already closed'

    
            RptScope = ReportScopeProvider.GetNewObjectScope();   
        
            using (RptScope)    
        
            {  
        
            InspectionReport result = (from ir in RptScope.Extent<InspectionReport>() select ir).First();   
        
            this.DataSource = result;   
        
              }

I am new to telerik reporting. I am using Business Object Datasource..
Here is the code...

But I get an Exception:'The 'IObjectScope' is already closed' when I preview the report design or when I run it.
But if I debug thru it , I do see the data being returned. ie. If I step through each line of code posted above , then the report shows the data else I get the exception.

Am I missing something ?

Restrict Number of Rows on Subreport before paging

I have a report that in the detail section, I have a subreport. That subreport could have 1 row or 50. After 15 rows, I would like the next 15 row to appear on another page, etc., etc..

Also, I have another subreport that I need to appear just on the first page. I currently have it on the master report in a group footer. I could put this anywhere as long as it only appears on the first page.

I have tried this many, many different ways.

Here's an example of what the report would look like.

The subreport detail section is where I need it restricted to 15 per page.

Please advise.

how to change the PlotArea appearence ???

Dear community,

for what ever reason it seems to be impossible to change the PlotArea color or to show major gridlines. I want my PlotArea plain white and major gridlines in grey. That's why I used the following code to achieve that:

    
            _gideonChart.PlotArea.Appearance.FillStyle.MainColor = Color.White;  
        
            _gideonChart.PlotArea.Appearance.FillStyle.SecondColor = Color.White;  
        
            _gideonChart.PlotArea.YAxis.Appearance.MajorGridLines.Color = Color.Gray;  
        
            _gideonChart.PlotArea.YAxis.Appearance.MajorGridLines.Width = 1;  
        
            _gideonChart.PlotArea.YAxis.Appearance.MajorGridLines.PenStyle = DashStyle.Solid;

Unfortunately the above code has no effect. Am I using the wrong properties? What are the right once then?
What else might prevent the changes from showing up?

Help would be highly appreciated.
Thanks in advance and kind regards,

Gerald

Blank HTML Page Rendering

Hello I asked this question before but did not get any answer.I am stuck with this problem ,can you help me please ?
Can you give me at least a clue to solve this problem ,I need help please

The problem

I have web site project and I wanted to test how I can use a class library in my project.
I created an aspx page in my website project and drag reportviewer user control of telerik reporting component.Then I references telerik reporting sample projects DLL (report library ) which comes with telerik installation .When I compile and run the page I saw a blank html page . on the top there is standard pager,zoom ,export tool bar but below there is no report content.When I try the expot pdf or excel option of this toolbar ,I can see sample report as a pdf or xls file.That means something prevent me to view html version of the report from my project.When I open sample web applciation projects in VB or C# ,I can run examples and see reports in reportview as HTML page.But in my project as i said when I add refernces and test I can not see the report as HTML .
I am pretty sure that I am binding reportviewer to correct report.AS I tried assigning both programatically and declaritively (from properties menu of reprotviewer user control).
In the light of above things ,what can be in my website project that prevent me to see html report ?
Thanks a lot

Business Object Binding Error

Hi

I configure the report with no DataSource and the following NeedDataSource event:

    
            private void AnalisiSconfinamenti_NeedDataSource(object sender, EventArgs e)  
        
                    {  
        
                        WSClass ws = new WSClass();  
        
                        List<Analisi> elenco = null;  
        
                        elenco = ws.analisi(9, new DateTime(2008, 5, 20), new DateTime(2009, 5, 20));  
        
                        (sender as Telerik.Reporting.Processing.Report).DataSource = elenco;  
        
                    }

The method ws.analisi is the following

    
            public List<Analisi> analisi(int id_cliente, DateTime fromData, DateTime toData)  
        
                    {  
        
                        UnicaDataContext db = new UnicaDataContext();  
        
                        //linq query to db  
        
                        var elencoFC = from e in db.Analisis ............  
        
                        return elencoFC.toList();  
        
                    }

When I preview the report I have the follow error:

Object reference not set to an instance of an object.

Where is the problem?

Thanks
Lorenzo
