(objectDataSource While Getting data From WCF)

Hi All,,

From your demos I fall in love with your products *_*,, So thank you a lot ....

I'm kind off new to Telerik Reporting Tool..

I have a WPF Application Built In MVVM (Model-View-View Model) and it Gets the data inside the Model from a WCF..
It works as a charm..

Now I want to replace the reporting feature in the application with the one your product is providing...

so I've started by creating a ReportsLibrary Project..
Then I've Created the DataSource as an objectDatatSource (So It Reads the data from the following method in the Model Class)

public static List<ALERT> Load()

{

List<ALERT> myList = new List<ALERT>();

AlertServices.AlertServiceClient AlertClient = new AlertServices.AlertServiceClient();

AlertClient.ClientCredentials.UserName.UserName = "usrName";

AlertClient.ClientCredentials.UserName.Password = "password";

ALERT[] dtAlerts = AlertClient.getAllAlerts();

foreach (ALERT alrt in dtAlerts )

{

myList.Add(alrt);

}

AlertClient.Close();

return myList;

}

Everything went smoothly with the report design which I have called AllAlerts..

when i tried to review the report before adding it to the WPF application I have got this Error Message...
(An Image Is Attached)

An error has occurred while processing Report 'AllAlerts':

Exception has been thrown by the target of an invocation.

------------- InnerException -------------

Could not find default endpoint element that references contract 'AlertServices.IAlertService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

To remove this message, please obtain a commercial version from www.telerik.com

Noting That I have Added The Project In The Same Solution That All It is Projects Are working soo fine..

And The Following (app.config) Configuration File is located in the ReportsLibrary Project..

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<system.serviceModel>

I hope That I will find the solution here.. *_*

By The Way I've Tried To View The Rreport from The WPF ReportViewer but I've Got Errors Adding The Viewer Control To The WPF View.. (So Lets Find a Solution for the First Problem First Then I Will Give You More Details About The Second One) *_*

Another sub-report binding question

I am binding my main report to an instance of an object that looks like this:

public class foo {
public Bar Header { get;set; }
public List<Baz> ListOfStuff { get;set;}
}

I have a sub-report that will display .ListOfStuff, but I'm at a loss on how to bind the sub-report so it has access this data from the main report.

At a high-level, this is how my main report is binding to the original source:

                var report = new TestReport();
                var ods = new Telerik.Reporting.ObjectDataSource();
                ods.DataSource = instanceOfFoo;
                report.DataSource = ods;
               
                instanceReportSource.ReportDocument = report;
                ReportViewer.ReportSource = instanceReportSource;

My sub-report doesn't have a DataSource set, so I've tried using NeedDataSource, but I'm not sure what exactly I need to do to bind to the parent data.

I'm sure I'm missing something really simple, but at this point, I'm stuck.

[Solved] using Column AVG and custom function

I use the below custom function to convert the numeric value in my Risk column to its text equivalent.

= ReturnRiskLeveltext(Fields.RiskLevel)

public static string ReturnRiskLeveltext(int rId)

{

using (DataEntities ctx = new DataEntities())

{

var RiskLevel = ctx.RiskLevels.Where(x => x.RiskLevelID == rId).SingleOrDefault();

return RiskLevel.Level;

}

However, in the footer row I wish to display an Average Risk Level

= Avg(Fields.RiskLevel)

Would be correct because it returns a 2. however, I wish to again display the Text equivalent.

= ReturnRiskLeveltext(Avg(Fields.RiskLevel))

Throws an error 'An error has occurred while processing TextBox 'textBox11': The expression contains undefined function call ReturnRiskLeveltext().'

Ideas?

How to remove BOM characters "ï»¿" from CSV file generated by ReportViewer export to CSV file

I am using Telerik Reporting version 6.1.12.820, Runtime version: v2.0.50727

I use ReportViewer to render the reports. If I export to CSV files when the report is empty, I noticed there are BOM characters "ï»¿" at the beginning of the file.

How can I remove it?

I searched the forum and found some post in Telerick Radgrid

http://www.telerik.com/community/forums/aspnet-ajax/grid/exporting-without-bom.aspx#1474434

But for ReportViewer, there is no such event handler.

Can you help?

Thanks

Data shows in Report Designer Preview but does not in Web Viewer

Overview: I am using Reporting Q1 2012 and Visual Studio 2010. I have built a very simple aspx page which contains the Q1 2012 Report Viewer control. In the code behind, I am binding the ReportViewer.Report to a deserialized instance of a .trdx file that was created using the Q1 2012 Report Designer. I have SQL Server Express 2008 R2 as the data source for the SQLDataSource defined in the report.

Problem: When I view the report (.trdx) in the Report Preview of the Report Designer, the expected data populates correctly. When I run the web application and attempts to view the report using the ReportViewer control a blank page is displayed after the "Generating Report.." message disappears. Print Preview mode of the ReportViewer yields the same results. Printing and exporting to any format generates a single blank page.

Details:

I have followed the official documentation for deserializing the report file and binding it to the viewer.
The report has no parameters and is a simple "Select * From [Table]" select command.
The [Table] has only three columns.
The SQLDataSource connection string is NOT being stored in a configuration setting.
I have stepped through the code line by line to verify that the deserialized Report object connection strings are pointing at the correct server and database with appropriate access.

Code:
viewer.aspx

Hide subreports based on selection criteria from website

I have a website that includes a report with multiple subreports. I have to add the functionality that the user can choose which subreports they can/cannot see. For example, the user may choose to only include reports 1,3 & 5, but not 2 & 4, or any of the rest. I will probably use some sort of list control to allow the user to select the subreports that they want included.

I have a reportviewer defined in my HTML:

<telerik:ReportViewer ID="ReportViewer1" runat="server" Height="500px" Width="100%">

<typereportsource typename="ETRrpts.IndividualSummary, ETRrpts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"></typereportsource>

</telerik:ReportViewer>

So what is the optimal way for me to identify, show and/or hide the subreports based on the user's selection?

Thank you!
