I have a pdf report that I am creating programmatically behind the scenes and I want to NOT create the report at all if there is no data.

I saw that RenderReport returns a result and I want to know if I can check to see if I get any rows in my NeedDataSource event handler and return and set an error there to have the PDF not be created.

Has anyone addressed a similar issue?

Deleting Items Programmatically

Hi there.

I have a report where I have a picture and a few textboxes in the report header. These items are only needed when the report is for a certain type of company. So, what I want to do check to see if it is that certain type of company, then delete/remove/hide those items programmatically. Is this possible? If so, where is the best place to do this?

Problem with xenocode postbuild

Hi guys,

I need to create an application with a single exe file, the app works after the xenocode elaboration but I have a problem when I try to generate a report.

Error message:

System.ArgumentException: Extension of type

'Telerik.ReportConverter.ActiveReports.ActiveReportsConverter' does not have name specified.

The error derive from this line of code:

Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("PDF", report1, Nothing)

I tried to find if I'm missing some dependencies but I didn't find nothing.

I'm using the telerik Reporting Q2 2009 and the xenocode postbuild 8.0.1112 on a windows seven machine.

thanks a lot!

Pie Chart doesn't display

My problem is after I assigned data to report by calling report constructor, put it into report viewer and called dataBind() of report viewer. It should show my Pie chart and legend, but it only display the legend.

    
                    public PieChart(Dictionary<string, int> results, ArrayList percentageResult)  
        
                    {  
        
                        InitializeComponent();  
        
                        ChartSeries chartSeries = new ChartSeries();  
        
                        chartSeries.Name = "Pie Chart";  
        
                        chartSeries.Type = ChartSeriesType.Pie;  
        
                        int i = 0;  
        
                        foreach (KeyValuePair<string, int> item in results)  
        
                        {  
        
                            List<Color> itemColor = new List<Color>(10);  
        
                            itemColor.Add(Color.Red);  
        
                            itemColor.Add(Color.Yellow);  
        
                            itemColor.Add(Color.Green);  
        
                            itemColor.Add(Color.Blue);  
        
                            itemColor.Add(Color.Brown);  
        
                            itemColor.Add(Color.Pink);  
        
                            itemColor.Add(Color.Orange);  
        
                            itemColor.Add(Color.Black);  
        
                            itemColor.Add(Color.Gray);  
        
                            itemColor.Add(Color.Olive);  
        
                            chartSeries.AddItem(item.Value, item.Key, itemColor[i]);  
        
                            chartSeries.Items[i].Appearance.FillStyle.FillType = Telerik.Reporting.Charting.Styles.FillType.Solid;  
        
                            chart1.Legend.Items.Add(new LabelItem(item.Key + ": " + item.Value + ": "  
        
                                + percentageResult[i] + " %"));  
        
                            chart1.Legend.Items[i].Marker.Appearance.FillStyle.MainColor = itemColor[i];  
        
                            chart1.Legend.Items[i].Marker.Appearance.FillStyle.FillType = Telerik.Reporting.Charting.Styles.FillType.Solid;  
        
                            i++;  
        
                        }  
        
                        chartSeries.Appearance.LabelAppearance.Visible = false;  
        
                        chart1.Series.Add(chartSeries);  
        
                        chart1.Series[0].Appearance.TextAppearance.TextProperties.Font =  
        
                new System.Drawing.Font(FontFamily.GenericSansSerif, 15);  
        
                        LabelItem labelItem = new LabelItem("chart");  
        
                        chartSeries.AddItem(10, "a");  
        
                        chartSeries.AddItem(20, "b");  
        
                        chartSeries.AddItem(50, "c");  
        
                        chartSeries.AddItem(100, "d");  
        
                        chart1.Series.Add(chartSeries);  
        
                        detail.Items.AddRange(new ReportItemBase[] { chart1 });  
        
                    }

,above is report constructor source code,

    
                        PieChart pieChart = new PieChart(results, percentageResult);  
        
                        ReportViewer2.Report = pieChart;  
        
                        ReportViewer2.RefreshReport();

and this is my calling constructor source code part.

I also checked out the items in chart1, there are data.

Conditional Formatting On a Table

I am trying to hide a table based on data. Are whole tables subject to conditional formatting? I have not even been able to get individual rows to see it.

Here is my expression:
=Reportitem.parent.dataobject.Tiertype = "4T"

Style result is Visible = false (unchecked).

This is the latest of many excpressions I have tried.

Thanks for your usual wise counsel.

Weird behaviour showing multi-params on report

Hi, I have used your example userdef function FormatArray() to show the value of multi params selected on a report. However since Q1 2010 some of the reports now show textbox errors at preview/runtime stating "An error has occured while processing TextBox 'TextBox8': The expression contains undefined function call FormatArray()."

It seems to be only if the textbox expression has spaces in between some static text and the function

i.e. "= 'Site: ' + FormatArray(Parameters.paramSite)" fails

but "= 'Site: '+FormatArray(Parameters.paramSite)" works

Copyright question

How do I update the copyright date that appears at the footer of all web pages, in a site that uses Telerik? I looked for a footer file, include file and also looked in the site source files but could not find it anywhere. Thanks for your help/instructions...
