For testing, I have a pie chart with 8 items.  The YValue of the item will be set in the NeedDataSource event. Since I am using the Telerik skin, the first item is green, second is yellow, third is red, and so on.  I need to have these color consistent since I will be referencing the color elswhere on the report.

Item1 = green
Item2 = yellow
Item3 = red
Item4 = blue

If I add only the items that have non-zero value the color will not be consistent.   For example, Item2 is zero then if I add Item1 then Item3:

Item1 = green
Item3 = yellow
Item4 = red
Item5 = blue

I need to make some of the items invisible.  However, setting Visible = false does NOT hide the item.  Suggestion?

I also tried the Remove() method but I get "An eroor occured while processing Chart... Object reference not set to an instance of an object."

 

I successfully bound the datasource of the reportviewer, but the reportviewer itself isn't showing anything up. What am I missing?


I haven been trying to set the design of a Telerik ReportViewer, but not succeeded.
Is there a how-to somewhere, where I can see how to bind the design?

Thanks in advance,

I have chosen the Mac skin and added a hatch to the Series-->Appearance-->FillStyle. In Fill Settings I have made my MainColor White and left the SecondColor what the skin populated.
In the designer the changes look the way I want and expect however at runtime it reverts back to the skin without hatching.
See the two images for a better idea. I am suspecting the Skin is overiding any changes I am trying to make.
Is there a way to add a hatch to series when you use a skin?

Thanks for any help

Hi Champs,

Hi,

I am also facing same problem to display hierarchical collections. My object is like below.

Class QuestionScenario
{
public string Name{get;set;}


private ModelVersion _modelVersion;
public virtual ModelVersion ModelVersion 
{ 
   get
   {
       return this._modelVersion;
   }
   set
   {
       this._modelVersion = value;
   }
}


private IList<Answer> _answers = new List<Answer>();
public virtual IList<Answer> Answers 
{ 
   get
   {
       return this._answers;
   }
}

}

public partial class ModelVersion
{
private Guid _modelVersionID;
public virtual Guid ModelVersionID 
{ 
   get
   {
       return this._modelVersionID;
   }
   set
   {
       this._modelVersionID = value;
   }
}


private IList<Question> _questions = new List<Question>();
public virtual IList<Question> Questions 
{ 
   get
   {
       return this._questions;
   }
}
}


Again question class has some property.

Now i want to display name from class QuestionScenario
and QuestionText from QuestionClass. i.e inside the modelversion class on My report page. 

If possible please give a sample.

Thanks in Advance.

We have some reports that have table with header and detail data and charts on the same report and some with just the table with header and detail data. So we are using the report viewer control in Asp.nEt MVC environment. Is there a better approach to this?

What is the best way to pass in data for the chart and the table with header and details on the same report.

Is it possible to add 3d graphs on reports(Without using WPF)?

Thanks in advance

I would kindly need to know if it is possible to have a custom text for labels on a chart pie slice different from the one set for legend items. Pie chart is bound to an ObjectDataSource.

e.g. Chart label displays the numeric value of the item while legend holds a descriptive name for the item.

Thank you in advance !

Hello Telerik,

I am concerned that the only development for the Reporting product is the stand alone Report Designer. The current RoadMap and the last couple releases seem to focus, almost exclusively, on this.

Are there intentions of updaing functionality in the standard development side of things?

Thanks,
John S.

Is there a way to setup optional parameters using telerik reporting?
I have a report that could potentially contain a large amount of data so I do not want to use filters if possible.
Ideally I'd like to define several parameters such as start start date and end date. If a user enters start date it returns everying greater than oir equal to that date, the end date returns everything less than or equal to it OR I could enter both dates and return all dates within the range. Theactual report is quite complicated and there will be more parameters but the general principle applies.
