Hello! I apologize for my poor English first.

I am a beginner on Telerik Report. I have to create a Pie chart that displays a datasource's data. Make my point clear:

I am making a Report build on three lists of objects, one object of every list it's named: Status (it can be: Open, On track, Cancelled etc...).

The chart should displays the average of every "Status" inside the three lists of the Report in percent (for example: Open 100%; Open 50%, Open 75% etc...)

The problem is: I don't know how to bind via code the Chart with the ObjectDataSource, I am using Graph Wizard.

I wrote this code 

 private void graph1_NeedDataSource(object sender, EventArgs e)
        {           
            Telerik.Reporting.Processing.Chart chart = sender as Telerik.Reporting.Processing.Chart;
            chart.DataSource = CbpGlobalInitiativesUsdByCountryFollowUpStructure; //it's the DataSource of the entire Report
        }

The Binding of the graph already has "Property path: DataSource", "Expression: =Field.List1 =Field.List2 =Field.List3"

I saw a tutorial and at this point the chart should already works, instead nothing happens!

Where am I get wrong?

Thank you,

Angelo

Hello,

I have been having a problem trying to generate a report programatically. I can generate columns just fine, but when it comes to trying to generate the rows, the ReportViewer gives me a NullReferenceException: "Object reference not set to an instance of an object." As I iterate through my list, I add a new row to the table body. Then, for every cell that needs to be made, I add a ChildGroup to the main Rowgroup. After I've finished iterating and generating everything, I finally add the parent RowGroup. From what I can tell, the way I add rows is close to the way it's done in the designer files. Here is the code in question:

The GenStandardColumnHeader and GenTextBox methods simply return pre-formatted textboxes, their first parameter being the value of the textbox. The properties of the object ChristieTable that I am iterating through are DataMembers consisting of a list of pairs. Using the debugger, I found that the report processes fine, but throws the exception when trying to render. Despite the fact that rows get clearly added, I found in the debugger that the row count for the table at render time is 0. Any help would be appreciated, thanks.

In my application I have to generate paper setter for online and offline test. I have done that so far quite easily, now my requirement is to create a dynamic template, so that while I print report it should fill all data inside created template.

I am also providing what I have achieved still now and what still need to be done more.. Please any one rescue me from here.

There is a stand alone report designer available in Telerik, please anyone guide me to use that. I think that might be suited for my need.

Or if anyone provide me a demo that will be highly helpful.

Hello,

I have a report that has two parameters.  When accessing the report parameters from the report CS file, the parameters are in the collection, but the values are blank.  Any help would be much appreciated.

Thanks,
Virgil

The code inside the BG0001 report

Intermediate window test of parameter values

I am using Nested sub report for this situation.

e.g.
Master Report - MainReport which contains Sub Report - SubReport1 and that Sub Report - SubReport1 also contain Sub Report - SubSubReport11.
SubReport1 has multiple data - e.g. Product 1,Product 2 etc.
SubSubReport11 has multiple data - e.g. Product 1 details, Product 2 details etc.
How can I bind data source for SubSubReport11 to get data for each product?

I have this type of scenario, so I have used Nested sub reports.

A. Main Report

       1. Sub Report 1

              a. Sub Sub Report 1 - It contains multiple data...(e.g. Line 1,Line 2,Line 3 etc.)

       2. Sub Report 2

              a. Sub Sub Report 2 - It contains multiple data...(e.g. Line 1,Line 2,Line 3 etc.)

If any other way to get this,please let me know.

Please give me any idea.
Thanks & Regards,
Bhavika

hi Team,

during run time can we swap rows or realign row order after generating the report.

is It possible to x axis and y axis in chart during run time.

we need to achieve above functionality using telerik reports.
