Error when opening a report in dotnetnuke which has a UI parameter visible

[Andraz]

I have installed a Trial version of Telerik Reporting Q1 2008 on my computer.
I created a page and placed a Telerik report viewer control.
All of the samples are working normaly except:

• Product Catalog Report
• Product Line Sales Report

which have a UI report parameter visible.
The program says:
A critical error has occurred.
Object reference not set to an instance of an object.

Then I created my own Report, added a parameter. It works fine until I set its UI property Visible = True.

Why is this happening?
Can you help me solve this problem?

Thank you very much and best regards.

Hello Andraz,

Thank you for your interest in our Reporting tool.

The information you have provided is insufficient for us to reproduce and isolate the problem. Is it possible for you to send us the call stack trace returned when the error occurs. Also please share what web browser and what version you are using and any other information you think might be useful.

Thank you in advance for your cooperation.

Best wishes,

Hi,

I am using Internet Explorer 7.0.5730.11 and
DotNetNuke version is 4.8.

this is the StackTrace of the error:

The ReportViewer page HTML looks like this:

<%

@ Control Language="C#" AutoEventWireup="true" Inherits="DotNetNuke.Modules.OIC.Shire.Reporting.TelericRepViewer" %>
<%@ Register Assembly="Telerik.ReportViewer.WebForms, Version=2.5.8.414, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>

<asp:UpdatePanel ID="upnRegMailListList" runat="server">

        </td> 
    </tr> 
</tbody>
</table>
</ContentTemplate>
</asp:UpdatePanel>

This ReportViewer gets a report name from URL like in the samples.

I am sorry if put too much code in this post. I hope you are not angry too much.

If you need more inforamtion, I will be glad to share it with you.

Thank you very much and best regards.

Hello Andraz,

Thank you for your patience and for the provided information.

Examining the stack trace I suppose that the thrown exception is connected with the localization of the report viewer.

If you are trying to localize the report viewer, please download and use the latest version of the .resx files from the KB article Localizing the Telerik Report Viewer. We apologize that till now, the most recent version was not uploaded there.

Let us know if that solves the issue you've encountered.

Best wishes,

Yes, that was it.

I downloaded the new version of the resource file like you said and now I can also use report parameters visually in Dotnetnuke.

But now I sill have one problem left. These newly added keys in the resource files are not being applied in the report webview control. But I will open a new support ticket for this. 

Thank you very much and best regards.

Hi Andraz,

You can use the Global Application Class (global.asax) and set the CurrentUICulture of the thread in the BeginRequest event of the application. For example:

public class Global : System.Web.HttpApplication
    {

        public Global()
        {
            this.BeginRequest += new EventHandler(Global_BeginRequest);
        }

        void Global_BeginRequest(object sender, EventArgs e)
        {
            System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("Fr");
        }

        protected void Application_Start(object sender, EventArgs e)
        {

        }

        protected void Application_End(object sender, EventArgs e)
        {

        }
    }

Hope this helps.
