NeedDataSource - change in 2010 Q1

I am doing reporting using a business object. The business object has sub-collections that I want to include in the report.

I used to do this to get to the raw data:

    
            Private Sub Table1_NeedDataSource(ByVal sender As Object, ByVal e As System.EventArgs) Handles Table1.NeedDataSource  
        
                Dim tab1 As Telerik.Reporting.Processing.Table = DirectCast(sender, Telerik.Reporting.Processing.Table)  
        
                Dim idata1 As Telerik.Reporting.Processing.IDataObject = DirectCast(tab1.DataObject, Telerik.Reporting.Processing.IDataObject)  
        
                Dim obj1 As myobject = DirectCast(idata1.RawData, myobject)  
        
                '  
        
                tab1.DataSource = obj1  
        
            End Sub

This no longer works in Telerik Reporting 2010 Q1. What the best way to get to the raw data object?

Brad

UPDATE: Looks like this is already reported as issue 1318 and I see a workaround another post on this same issue. I will try the workaround until there is a better method.

Report preview and WCF datasource : endpoint not found

Hi,

I'm trying to configure Telerik Reporting to make the preview able to get datasource from WCF Webservice. In runtime mode, it works well, but in design mode it tells me that the endpoint is not found. I think the configuration file is not found and tried to copy it into some bin folders but nothing works. Here is my project organization :

-1) a Web project that launches the silverlight app

-2) a Silverlight application project that hosts a Silvelright Report Viewer

-3) a WCF Webservice project that gives the possibility to grab datas from the DB.

-4) a standard class library project that contains my reports

My reports make calls to webservice through WCF but the preview doesn't work.

Where do I have to copy a configuration file to make it works ? and how do I have to name it please ?

In fact, what I would like to know is : when you click preview in the report designer, in which folder is run the preview rendering ?

Thanks,

Regards

Getting Labels Layout constructors and models lists

Hi,

My client has to set his label sizes at runtime. I've made all the code to make this works, but I was wondering if I could get the same list of layouts as the reporting wizard to present it to my client and then initialize all values I need to create the report.

It would be a great functionality to avoid the user to write all values if he uses a standard labels layout and would make him free to modify or write all values if he uses a non standard one.

Is there any way to get the two lists presented in the wizard (constructor like AVERY and models like L7160) and then get their layout values ?

Thanks

Regards

Cannot get report to view in Report Viewer Silverlight

HI,

Im new to the Report Viewer control but very interested in implementing into our Silverlight Application. I have followed the Video tutorial and looked through the example project on how to create and view a simple report, however im getting the following error:

'Could not load type 'TenantsDetails' from Assembly 'Telerik.Reporting.Service' version=4.0.10.310, Culture = Neutral, PublicKeyToken=a9d798dfcc261be'

I have scoured your forums but there is no clear solution. I have made sure im using all the correct refereneces, have the latest versions of Reporting and RadControls and i cannot for the life of me figure out whats going wrong.

Here is my code to my report viewer

    
            <controls:ChildWindow x:Class="ColonySL.ReportViewer" 
        
                       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"   
        
                       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"   
        
                       xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" 
        
                       xmlns:telerik="clr-namespace:Telerik.ReportViewer.Silverlight;assembly=Telerik.ReportViewer.Silverlight"               
        
                       xmlns:telerikNav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation" 
        
                       xmlns:telerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls" 
        
                       xmlns:telerikPrimitives="clr-namespace:Telerik.Windows.Controls.Primitives;assembly=Telerik.Windows.Controls" 
        
                       xmlns:telerikInput="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"     
        
                       Width="1024" Height="700" 
        
                       Title="ReportViewer">  
        
                <Canvas Name="Main">  
        
                    <telerik:ReportViewer Grid.Row="1" x:Name="ReportViewer1"   
        
                                              Width="1008" 
        
                                              Height="660" 
        
                                              ReportServiceUri="../ReportService.svc" 
        
                                              Report="TenantsDetails"/>  
        
                </Canvas> 
        
            </controls:ChildWindow>

and attached is a snap shot of how my project looks.

I would be grateful if you could get back to me asap as we are very interested in getting this working with our project and would like to purchase if we can get this working.

Thanks,

Are Report "base classes" or templates possible?

Hi Everyone,

I have dozens of reports to create in my application. Of course they all show different data, but they ALL have some common elements, such as company name and logo, page #, and printed date/time, and those common elements also need to be positioned the same.

So, is it possible to create a base class with Telerk reporting, that would contain these common elements? And would it be possible to somehow inform the Telerik Report Wizard to use that "base report class" when it's fired up for a new report?

Thank you much for any and all advice and suggestions!

Dan

Setting the Width of a GroupSection programatically

I want to build a report in which, based on some conditions, I don't want a column to be visible. I've configured conditional formatting on the report items that are part of that column, and it works. However, I want to shorten the width of the GroupSection where the header of the column is placed, in case it is not visible. Then I implemented the ItemDataBinding event tied to the GroupSection, but I figured out that the Width property doesn't exist to be set programatically for a GroupSection! Am I missing something? It's funny I can set the width from the designer in VS for a GroupHeader, but I can't do it programatically.

Problem with Date filters that use conversion functions

I cannot seem to get a Date filter to work that uses conversion routines. The schema which I'm reporting against stores all dates as OLE automation dates (double precision floating point). I have a static utility function, DateTime MyLib.Utilities.FromOADate(Nullable<Decimal> dt) which wraps the System.DateTime.FromOADate() routine and exposes it to the report. This way, in the report I can use an expression, e.g.={MyLib.Utilities.FromOADate(Fields.[StartDate])}. This seems to work correctly for report output.

When I try to setup a filter for start date using a similar method, I get an error 'Cannot apply >= to types System.DateTime and string'. When I use the expression editor, the expression created is:

=MyLib.Utilities.FromOADate(Fields.[StartDate]) (without the {}'s, adding them seems to be a syntax error )

My filter definition looks like:

Expression Operator Value

=MyLib.Utilities.FromOADate(Fields.[StartDate]) >= =Parameters.Parameter1 (DateTime)

=MyLib.Utilities.FromOADate(Fields.[StartDate]) <= =Parameters.Parameter2 (DateTime)

I've barely started to look into Telerik Reporting so I may be missing something obvious. Any help would be appreciated.

Thanks,

Josh
