Why not IEnumerable as Datasource on ObjectDataSource?

Why can't I connect an object that implements IEnumerable as a DataSource on an ObjectDataSource? The following class is allowed:

public class MyClass

{

private int test;

public int Test

{

get { return test; }

set { test = value; }

}

public IEnumerator GetEnumerator()

{

return null;

}

but if I add ": IEnumerable" after "MyClass", the Data Explorer on the report only displays the message "No Data Source"

I'm using Telerik Reporting 2010 Q2 SP1 (4.1.10.921)

BTW: My real class returns an enumerator from GetEnumerator(), that is not the problem...

Sverre

public class MyClass

{

private int test;

public int Test

{

get { return test; }

set { test = value; }

}

public IEnumerator GetEnumerator()

{

return null;

}

Copies of Report

I'm evaluating the component and everything seems to be working perfectly but there is one thing i want to do and i cant find a way.

I have a report that generates only 1 page (wich is correct) but i need to print 3 copies and put in the report the number of each copy (1,2,3) or "original, duplicate, triplicate) ...

How can we achieve this?

thanks,

Joaquim

Error while displaying unvalidated Html tags in HTMLTextbox

Hi,

I have a Windows application which uses the Telerik Reporting for displaying reports.

The Windows application has many comment fields (contains rich text - data copied from Word, Exel, PDF).
The comments data could contain Chinese, European, Indian etc alphabets.
Styles like Font change, Bold, italics, highlights can be applied to the comment fields

4. The data is stored in the Access Database

Issues are as follows:

When these comment fields are to be displayed in the Reports--> HTMLTextBox, (since richtext htmlTextbox is used) error occurs as the HtmlTextBox is unable to identify the html tags (mostly generated by Word, Excel and Pdf).

Steps Followed

Place the HTMLTextbox controls in the detail section of the Reports
HTMLTextBox --> Properties --> Value --> Bind the Comment field from the database to the control
Properties -- > Change the Font to Arial Unicode MS to accept other language characters
Build report.
This report is called from the Windows Application.

Please find attached a sample HTML generated from the Word and the error occured.

Please note..
When these Html generated tags is directly copied into the Design View of Editor properties of the [HTMLTextBox--> Value ]
and switch back to HTML mode, they are displayed fine when you Preview from the Report project (like harcoding) . I have noticed that the Design view of the Editor Properties validates the HTML to proper Html tags. But the HTMLTextBox as such fails to do the same.

The reports needed for the application is dynamic data.

Please need a solution to this..

Thanks
Shalini

ReportBook not showing in ReportViewer

I hope I haven't missed a post, but somehow I can't get the reportbook (Q2-2010) working. I've got the following code:

srMTO.MTOwsSoapClient soaplink = new

srMTO.MTOwsSoapClient();

dsCompleteQuestionnaire1 = soaplink.GetCompleteQuestionnaire( QuestionnaireId );

Telerik.Reporting.Report QuestionnaireReport =

new reports

.rap_CompleteQuestionnaire();

QuestionnaireReport.DataSource = dsCompleteQuestionnaire1;

QuestionnaireReport.DataMember =

"CompleteQuestionnaire"

;

ReportBook QuestionnaireBook =

new

ReportBook();

//QuestionnaireBook.Reports.Add( new Rapporten.rap_CompleteQuestionnaire_Front() )

QuestionnaireBook.Reports.Add( QuestionnaireReport );

reportForm.SelectedReportBook = QuestionnaireBook;

(last two lines are in reality not commented)

and the other form (reportForm with the ReportViewer):

Telerik.Reporting.ReportBook report = SelectedReportBook;

this

.reportViewer1.Report = report;

this.reportViewer1.RefreshReport();

I had it working for the QuestionnaireReport (the same way), but realized I needed a front page. So I needed the ReportBook. But the content is just not showing. Neither with just the QuestionnaireReport.

Any ideas what I'm doing wrong?

PS. I know that the DataMember of the report is obsolete, but attaching it to the objectdatasource this way is not working (for me).

LINQ and Reports

Hello,

I am fairly new to using Telerik Reports and was wondering if it is at all possible to use LINQ as a DataSource for these reports. My end goal is to call an IQueryable Function, while passing in a Username and Time Period to generate the Report for that User.

public static IQueryable GetUserReport(int UserID, string Period)

{

DataContext Data = new DataContext();

var Reports = (from c in Data.UserInfo

where c.UserID == UserID && c.Period == Period

orderby c.UserID ascending

select c);

return Reports;

}

I have tried using SQL DataSources in my Reports, but would prefer to use LINQ if at all possible. Do Telerik Reports support the use of LINQ, or am I spinning my wheels on this one?

EDIT: Note, I am currently using what I believe is the newest version:
Telerik Reports: 2010.3 1110
RadControls for ASP.NET + AJAX: 2010.3 1109

Best Regards,

Landon

transparency on image export ?

Hi,

we're still evaluating Telerik Reporting, especially the Silverlight components.

One problem we've found so far is, that it seems the image export does not obviously support transparent background colors.
Currently we tried the TIFF-Export using the Silverlight Report Viewer and the API of the rendering engine itself, both without luck.

What did we miss to get transparent background images (preferrably in PNG format) using the server side API ? Examples would be very appreciated ;)

Thank you so far and kind regards

Sebastian

Simpler way of initializing Reporting element?

I'd like to find a simpler(and better) way of initializing an element.

Let me take an example of TextBox.
Because of Type conversion and etc. It is quite messy.

The following code is what I have as a solution. I used extension method.

Is Telerik going to provide something similar to this?

double leftPoint = 0;

       double Y_FirstLine = 0.02;

double width = 1.25;

double height = 0.25;

Telerik.Reporting.TextBox textBox;

// Add ItemInfoId Box

textBox = new Telerik.Reporting.TextBox();

textBox.SetTextBoxAttribute("ItemId", leftPoint, Y_FirstLine, width, height);

groupHeaderSection1.Items.Add(textBox);

// Add Cost Box

leftPoint += 0.6;

textBox = new Telerik.Reporting.TextBox();

textBox.SetTextBoxAttribute("COST", leftPoint, Y_FirstLine, width, height);

groupHeaderSection1.Items.Add(textBox);

// a lot more of TextBoxes ...

public static class TextBoxExtension

{

public static void SetTextBoxAttribute(

this Telerik.Reporting.TextBox itemBox,

string value, double left, double top, double width, double height)

{

itemBox.Value = value;

itemBox.Location = new Telerik.Reporting.Drawing.PointU(

new Telerik.Reporting.Drawing.Unit(left, Telerik.Reporting.Drawing.UnitType.Inch),

new Telerik.Reporting.Drawing.Unit(top, Telerik.Reporting.Drawing.UnitType.Inch));

itemBox.Size = new Telerik.Reporting.Drawing.SizeU(

new Telerik.Reporting.Drawing.Unit(width, Telerik.Reporting.Drawing.UnitType.Inch),

new Telerik.Reporting.Drawing.Unit(

height, Telerik.Reporting.Drawing.UnitType.Inch));

}

Display report based on Parameters

Hi,
I am new to Telerik reporting. I have one report which has a text box control. I need to display this report for two text box values. I can hardcode these values but I don't know how to display a single report as two reports based on the value.

Textbox1.value = "ACTIVE COPY";
textbox1.value = "File Copy";

I want to display same report for these two values.

I appreciate your help.

Thanks
Raj

The name already exists in the tree

I am getting an error
"The name already exists in the tree: _10_035".
on one of my reports in the Silverlight Viewer only.
The report has Document Map and Bookmarks set.
This error does not come up with other reports or in the Designer Preview
Any tips as why this error would only come up in the silverlight viewer?
