Whenever merging cells I'm always left with the style and content of the left most cell.

[Cell1][Cell2][Cell3][Cell4]
If I Select all cells and then Right Click on Cell2 to merge the cells, I end up with Cell1 and Span4 but I would like Cell2 with Span4.

Is there anyway to define which cell to keep in the merge?
Until then I'll have to copy my src cell in the designer file.

Thanks

AutoRefresh on only one parameter while other parameters need not AutoRefresh

I have a report with 4 visible parameters and only one has AutoRefresh on. We have recently upgraded this report to Q3 2012 version. I was able to refresh the report when the AutoRefresh parameter value is changed with the previous releases. But after I upgraded the report to Q3 2012, this feature is not working. I do need the Preview button for other parameters.

Please let me know how can I refresh the page when this parameter is changed without having to click the Preview button.

Thank you

Subtotal a field that occurs in a group total

I have a report that is using Q1 2013 (6.2.13.110). This is a WINFORMS application written in VB.NET 2010

I have 3 group sections on the report where group 2 ("CltName") has a few summary fields as well as a Last(xxx) field (lets call it "GroupEndBalance". I would like to create a summary field for "GroupEndBalance" in the "CltMasterNameGroup" but reporting will not allow a Sum(Last(xxx)) or a Sum(GroupEndBalance).

How can I get a summary of the "GroupEndBalance" field into the "CltMasterNameGroup".

I think if I was able to create a global variable and store the sum of this value on group2 change that may work but I am unsure as to how to accomplish that.

I have attached a screen shot of what the design of the report is so you can get an idea of what it looks like.

Any detailed ideas would be helpful.

Report Chart Unable to change series items in runtime

Hello,

I am trying to add series and series items at runtime to an empty chart in a report.
However, albeit I can see the changes I'm making at runtime happening they do not reflect in the Chart.

Here's my NeedDataSource Event code:

    
                    private void chart1_NeedDataSource(object sender, EventArgs e)  
        
                    {  
        
                        List<Product> produtos = new List<Product>();  
        
                        produtos.Add(new Product() { qty = 10, name = "Produto 1" });  
        
                        produtos.Add(new Product() { qty = 35, name = "Produto 2" });  
        
                        produtos.Add(new Product() { qty = 17, name = "Produto 3" });  
        
                        produtos.Add(new Product() { qty = 65, name = "Produto 4" });  
        
                        ChartSeries serie = new ChartSeries();  
        
                        foreach (Product prod  in produtos)  
        
                        {  
        
                            ChartSeriesItem item = new ChartSeriesItem();  
        
                            item.YValue = prod.qty;  
        
                            item.Name = prod.name;  
        
                            item.Label.TextBlock.Text = prod.name;  
        
                            serie.Items.Add(item);  
        
                        }  
        
                        chart1.Series.Add(serie);  
        
                    }

If I execute this code, the chart will be EMPTY...and showing the message: There is no or empty Series. And the Legend has 1 Item with a label text of Series xx.

IF I eventually change my NeedDataSource event to:

    
                    private void chart1_NeedDataSource(object sender, EventArgs e)  
        
                    {  
        
                        List<Product> produtos = new List<Product>();  
        
                        produtos.Add(new Product() { qty = 10, name = "Produto 1" });  
        
                        produtos.Add(new Product() { qty = 35, name = "Produto 2" });  
        
                        produtos.Add(new Product() { qty = 17, name = "Produto 3" });  
        
                        produtos.Add(new Product() { qty = 65, name = "Produto 4" });  
        
                        chart1.DataSource = produtos;  
        
                    }

The chart will show the values correctly. However I can't change each indivual item values or appearance at runtime! Firstly, I get an exception if I try to use the following line after chart1.Datasource = produtos:

    
ChartSeries
 
series = chart1.Series[0];

I get an out of bound exception.

If I put that line of code on the ItemDataBound Event it works fine:

    
            private void chart1_ItemDataBound(object sender, EventArgs e)  
        
            {  
        
            ChartSeries series = chart1.Series[0];  
        
            series.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels;  
        
            series.Type = ChartSeriesType.Pie;  
        
            }

As a side note, I'm loading the report on a reportviewer and I initialize it like so:

    
                    private void Form1_Load(object sender, EventArgs e)  
        
                    {  
        
                        reportViewer1.Report = new ReportTest();  
        
                        reportViewer1.RefreshReport();  
        
                    }

Even though I'm calling the RefreshReport Method, whenever I execute the application I'm forced to manually press the Refresh Button on the report viewer just to watch my ItemDataBound code be actually rendered...what the heck?!

Back to my ItemDataBound event...I can actually access the serie's Items, but any change I make to them (be it YValues or Appearance stuff) it WONT reflect on my reportviewer no matter how much I smash the refresh button!

Here's my complete code:

ReportTest.cs
(chart1 was just dropped onto the detail section in Design time. No other changes were made!)

    
                using System;  
        
                using System.ComponentModel;

                using Telerik.Reporting.Drawing;  
        
                using System.Collections.Generic;  
        
                using Telerik.Reporting.Charting;  
        
                public partial class ReportTest : Telerik.Reporting.Report  
        
                {

                    {  
        
                        InitializeComponent();  
        
                     }

                        produtos.Add(new Product() { qty = 10, name = "Produto 1" });

                        produtos.Add(new Product() { qty = 17, name = "Produto 3" });  
        
                        produtos.Add(new Product() { qty = 65, name = "Produto 4" });  
        
                        chart1.DataSource = produtos;  
        
                        ChartSeries series = chart1.Series[0];  
        
                    }  
        
                    private void chart1_ItemDataBound(object sender, EventArgs e)

                        ChartSeries series = chart1.Series[0];

                        reportViewer1.RefreshReport();  
        
                    }  
        
                }

Please help... I already lost a whole day of work trying to figure this out.

P.S.: I followed EVERY single tutorial regarding adding series at runtime and NONE OF THEM WORK on my end.

Drilldown report: expand all items

Hello!

Is there any way, coding or not coding, to achieve this ? I'll need to make a report that has 1 level of drilldown. I would like to be able to expand all presented items so I can print out the report expanded.

Is there a way of doing this or I may as well keep on dreaming? :D

Regards!

Trying to work with a chart in a trdx report file.

Hello, I am trying to set up a chart in my trdx report file and I am not have much luck formatting it. When I added the chart to the report I then set my DataSource for the chart. When I right click on the chart and select Properties, the data tab displays a message "To dynamically populate the chart with data set the chart's DataSource property". I did this step so I'm not sure what else I can do.

Also, the data I am providing has a UserName, Phone Extension, Number of minutes on phone per hour and the datetime (in one hour increments). When I preview the chart it does show data from the DataSource, but it shows the telephone extension and hours per minute on phone as my values. I try to set the X-Axis to use the datetime value, but it is not taking it correctly.

I would appreciate your assistance in resolving this issue. I am currently using Version 6.2.12.1017 of the Telerik Report Designer.

I am able to create a stand alone trdx file that outlines the problem I am having. Since you are only accepting image extensions can you please let me know what I can do to send you my trdx file.

Thanks,
