Hi,

I can create the report rendering to XLSX format but a message box will be displayed before the report:  How to avoid this message box?  Thanks.

Hi. I have a Report with Pie Chart that displays number on purcentage based on data in a list.

When the Report repeats itself and finds no data, the Chart Pie disappears. I need a way to display an empty Chart Pie with 0% when there is no data on the list. 

How can I do it?

Sorry if I open another thread, but I need help about Pie Chart.

I created a Pie Chart, and I have three questions about it:

1. How can I fix the size of the entire Chart?

2. How can I fix the size of every slice based on percent? (how you can see, the slice have all the same size even if different values))

3. Why every label near % repeat a number 0,00%?

Here the screenshot, hope you can help me.

Best regards.

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.
