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

Count(RowNumber()) error after upgrade

After upgrading to the newest reporting version, a report that had been working fine previously started giving the following error:

An error has occured while processing Report '':
Unable to cast object of type 'DataObject' to type 'Telerik.Reporting.Expressions.IHierarchicalData'.

After some experimentation I found that removing the textbox in the report's footer that used Count(RowNumber()) (to display the total count of detail items) the error went away and the report worked as before. How can I show the count without getting an error?

Thanks,
Mike
