I've added the following code to my web.config file to disable certain export types and the rendering of column headers as rows in my Excel export:

    
            <Telerik.Reporting> 
        
                <Extensions> 
        
                  <Render> 
        
                    <Extension name="CSV">  
        
                      <Parameters> 
        
                        <Parameter name="NoStaticText" value="true"/>  
        
                      </Parameters> 
        
                    </Extension> 
        
                    <Extension name="IMAGE" visible="false" /> 
        
                    <Extension name="MHTML" visible="false" /> 
        
                    <Extension name="RTF" visible="false" /> 
        
                    <Extension name="XPS" visible="false" /> 
        
                  </Render> 
        
                </Extensions> 
        
              </Telerik.Reporting>

It works exactly as expected in my development environment (IIS 5.1), but when I deploy to our stagining/production (IIS 6) environment, I get the follwoing error when I load a page containing the Report Viewer.

Begins

Good evening,

It is the first time we'll mecher with reporting, I would like to address some questions before starting work.

- Can I integrate it with an application. NET in visual studio with visual basic language?
- Can I create the report parameters, where I set out for its value, through an aspx page?
- Can I pass all parameters of connection / table to be used, an alert parameter in a aspx page?
- It is advisable / possible to generate payment slips through the reporting?

These questions are because I have this report in crystal reports, and now need to migrate p / a platform net, so I wonder if I can use the tool to you, or I will have to continue with crystal reports.

Already, many thanks.

Build error with Telerik ReportViewer control

I am getting the following error when I try to build an ASP.NET web forms application in my solution with the Telerik ReportViewer control:

The type 'Telerik.ReportViewer.WebForms.ReportViewer' exists in both 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\appdevcenter\94dab5a4\8ccebc39\assembly\dl3\aa719e0f\0c7fc604_7790cd01\Telerik.ReportViewer.WebForms.DLL' and 'c:\Windows\assembly\GAC_MSIL\Telerik.ReportViewer.WebForms\6.1.12.820__a9d7983dfcc261be\Telerik.ReportViewer.WebForms.dll' C:\inetpub\wwwroot\LearningCenter\appDevCenter\Reports\TrainingHistory.aspx

How do I resolve this error?

Passing Parameters to filter report

Hello,

I have a reports that I built in seprate class in web app. The reports are then viewed in web report viewer that also contains date inputs and drop downs to pass parameters to filter report in a custom user control (ascx). The report initally loads fine, but I cannot change the parameters with the drop down controls. What am I missing?

Sub LoadReport(ByVal serviceTypeID As Integer)

Dim report As Telerik.Reporting.Report = DirectCast(Me.rvServicesSummary.Report, Telerik.Reporting.Report)

Dim thisUser As String = Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey.ToString

Dim agencyGuid As String = UserProfile.GetCurrentAgencyGUID.ToString

report.ReportParameters("ServiceTypeID").Value = serviceTypeID

report.ReportParameters("CurrentUserID").Value = thisUser

report.ReportParameters("AgencyGUID").Value = agencyGuid

End Sub

Protected Sub RcbServicesSelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rcbServices.SelectedIndexChanged

LoadReport(CType(sender, Telerik.Web.UI.RadComboBox).SelectedValue)

End Sub

Binding to Business Object

I'm a bit confused about how to bind my report to a business object. I've been able to get my object into the 'DataSource' property of my report, but I would think that at this point I'd have to specify the method which is responsible for populating the DataSource. However, I'm not sure where to specify this method? My business object is listed below, it is relatively simple and I'm currently just creating some debug objects in a method that will eventually pull from the database:

    
            Imports System  
        
            Imports System.Data  
        
            Imports System.Configuration  
        
            Imports System.Web  
        
            Imports System.Collections  
        
            Imports System.Collections.Generic  
        
            Imports Triton.TCNext.EntityLayer  
        
            Public Class TransactionType_BAL  
        
              Inherits List(Of TransactionType_BAL)  
        
              Sub New(ByVal id As Integer, ByVal name As String, ByVal description As String)  
        
                Me.ID = id 
        
                Me.Name = name 
        
                Me.Description = description

                  Return New TransactionType_BAL(transactionType.ID, transactionType.Name, transactionType.Description)  
        
                End If  
        
              End Function  
        
              Private Shared Function GetTransactionTypeListFromTransactionTypeEntityList(ByVal recordSet As List(Of TransactionTypeEntity)) As List(Of TransactionType_BAL)

                For Each record In recordSet  
        
                  transactionTypes.Add(GetTransactionTypeFromTransactionTypeEntity(record))  
        
                Next  
        
                Return transactionTypes  
        
              End Function  
        
            End Class

My initial approach was to create a BLL, a DLL, entity objects to pass between the two, then implement stored procedures in the DB. My thought was that I would have a method in my BLL that would populate a collection of objects then pass this collection to the report for display. To populate the collection, the BLL would call a method in the DAL which in turn would populate an entity object (or collection of entity objects) based on the data retrieved through the utilization of stored procedures in the database. The BLL would then convert these entity objects to business objects which could be passed to the report in a strongly-typed collection.

Does this approach seem feasible? Is this overkill?

Issues with the Reporting Demo on an iPad

Hello,
We are having issues with the Sales Dashboard demo for Telerik Reporting available here: http://demos.telerik.com/reporting/sales-dashboard/demo.aspx - namely, the report itself will not scroll on our iPad 2's. Any attempts to scroll just move the page instead of scrolling the report.
Is this a known issue? Are there any suggested workarounds?

Override error message

Hi

When I have already opened a file, and I'm trying to save a report with the same name, I get the following message:
The process cannot access the file 'C:\1.pdf' because it is being used by another process.

How do I change this message to others, or may I call my popup?

Visual Studio Toolbox double icons

Hi,

Everytime after i open visual studio and open any design (even if it's an xaml file), the toolbox items for telerik are added... by now each icon appears already 4 times.

It's extremely enoying because it hangs visual studio during the time that the icons are added.

In att. you'll find proof.

I'm using Q1 2011, Visual Studio 2010, Win7 Pro 64 bit
