06. Location = new PointU(Unit.Inch(0), Unit.Inch(0)),

07. Size = new SizeU(Unit.Inch(8.0D), Unit.Inch(3.0D)),

08. StyleName = "Normal.TableGroup",

09. DataSource = src,

10. Name = "graph"+colIndex.ToString()

11.};

12.

13.test.Titles.Add(new GraphTitle() { Text = "% of" + ReportTitle });

14.

15.BarSeries pie = new BarSeries();

16.pie.Name = "pie" + colIndex.ToString();

17.var pallet = new ColorPalette();

18.pallet.AddColors(Color.Red, Color.Blue, Color.Green, Color.Yellow, Color.Orange);

30.GraphGroup series = new GraphGroup()

31.{

32. Name = "series1"

33.};

34.series.Groupings.Add("=Fields.PercentOfTotal");

35.//series.Sortings.Add("=Sum(Fields.PercentOfTotal)", SortDirection.Desc);

36.//series.Sortings.Add("=Fields.IngredientName", SortDirection.Asc);

37.//series.Filters.Add("=Sum(Fields.PercentOfTotal)", FilterOperator.TopN, "20");

38.pie.SeriesGroup = series;

39.test.SeriesGroups.Add(series);

71.

72.pie.X = "=IsNull(Sum(Fields.PercentOfTotal), 0)";

73.pie.LegendItem.Value = "=Fields.IngredientName";

74.pie.ArrangeMode = GraphSeriesArrangeMode.Stacked100;

Object Data source wizard throw an error

I have an existing Telerik report - designed in Visual Studio. It's been in production for several months. When I try to change the object data source on it now, it throws an error (can't load type xxx from assembly xxx). There's absolutely nothing wrong with my assemblies, this project compiles and runs fine and has been in production for several months as I said. Any idea what's causing this? I cannot contact support because the license has expired.

Toggle Visibility - Display expanded

Hi,

I have a new problem when I apply the Expanded Display Toggle Visibility. The check box "Toggle mark initially expanded" is not working. As you can see in the attach images, the result in the Crosstab open always expanded whatever choice I make.

As you can see in image "Im-Result" a plus signal (+) is showed next to brand. If I click in the plus signal the table collapse.

Can please someone help?

Thank you.

Report book

Hello

Will it be possible in the next releases to create a report book with the desinger?

Basically I need 2 pages for a report of the same content, but with a different layout.

Can that be achieved by a single report?

Installing Reporting Services on .Net 4.6.1

We are considering purchasing Telerik Reporting but have encountered an issue while trying to install for a trial.

I am trying to install the Telerik.Reporting.Services.Mvc6 but it fails with:

"Could not install package 'Telerik.Reporting.Services.Mvc6 10.0.16.204'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.6.1', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author."

Can the service be installed in .NETFramework version 4.6.1?

Thanks

Authorization header ignored in reporting REST api during the actual rendering of the report?

Hi

I am currently rewriting an old Silverlight Application in Angular. The original application had some reports which I would like to reuse.

So I added a REST service to my web api by following the instructions in the docs. This seems to be working (http://localhost:[portnumber]/api/reports/formats returns the expected result). I also created a HTML5 viewer (in Angular), and made sure the authorization token is set (I'm using OAuth).

Unfortunately the report doesn't show..

I started to investigate and, as you can see, the network traffic reveals several requests to the report service are triggered. The next to last request appears to contain the contents of the report in html, but in fact this html is just an error page.

While debugging I discovered that the request doing the actual rendering of the report is not authenticated and HttpContext.Current.User is null.
My code to retrieve the report data relies on this user and therefor throws an exception. The authorization header is present and correct but is somehow ignored.

In all other requests to the reportservice the request is authenticated and the current user is correctly filled, just not for this one request doing the rendering.
Do you have any idea what might be causing this?

Dynamic Report at runtime

Good Morning,

I've have seen in previous posts that with telerik reporting it's possible to create a report a Runtime, passing a object data model.

But reading this post I've seen that this can cause problem and there is not a best solution to create report (the post had been created on 2012 and 2013)

Now I want to know if this solution it's advisable or it's better create one report from each model and bind them by the import wizard of telerik report.

Thanks
