Good Morning,

I have installed the Telerik Reporting Quick Start (Q1 2008) and when click on any of the Web Sample buttons I get the following error:

Exception Details: System.InvalidOperationException: Failed to map the path '/'.

Source File: c:\Users\Ernie Josefik\AppData\Local\Temp\Temporary ASP.NET Files\telerik_reporting_q1_2008\af2259b4\155f256f\App_Web__tbkx_g5.0.cs Line: 0

The operating system is Vista Business and I get the same result if I run the Quick Start application from the menu or open the WebDemo application in VisualStudio 2008 and run it from there.

Any assistance would be appreciated.

Cheers

Very Nice Job

I have always used crystal reports for my reporting needs, it's quick and simple so I never thought I would need your reporting tool.

But a few days ago, I tried to create a purchase order in CR, and was hitting walls because I needed to access non-normalized data in a legacy database with a lot of business rules that had to be observed and CR could do some of the work, via subreports and shared variables between the reports but it was going to be very difficult to maintain and support this report in the future.

However when I cracked open Telerik Reporting, and was able to use multiple datasources within my report, and alter the values at runtime (item_databound_events), the value of your reporting tool just shot up to the top of my list.

I can do so many more things with your tool than I could ever do with CR when it comes to multiple datasources and accessing muliple platform databases.

Thanks,

Tim

p.s. Crosstabs would be nice :-)

Data connection problems

Hi :o)

I've now sorted my reports - all looking cool.

Now that I've come to deploy the app onto my webserver I seem to be having problems with data connections.

Is there an easy way to change the connection string of the datasets within the report project.

Thanks

Tim

Programatically accessing controls within a report

Many thanks

Unable to Preview Reports

Good Morning,

As per the tutorials I have created a ReportsLib class library which is referenced from a web app. Database access is via a DAL which is also a separate class library compiled into a dll. Databinding is to business objects returned by the DAL. This all works fine when the reports are called from the web application.
However when I try and preview the reports in the designer I get an Exception as follows:

Exception has been thrown by the target of an invocation. Unable to read connection string from the .config file.

This is similar in nature to when I referenced the DAL from a separate Unit Testing class library. Obviously the class library projects do not have access to the web config containing the connection string. In that case creating an app.config containing the connection string in the UnitTest project did the trick.

Unfortunately the same approach did not work for the ReportsLib project. Is there something else I need to do to get the preview functionality to work if my datasource is obtained from another class library which obtains its connection string from the config file?

Any assistance is much appreciated.

Cheers

P.S. running version Q1 2008

2 reports within 1

Hi :o)

I am trying to create a report that is similar to a mobile phone bill.

The first page is a summary of usage which is like an invoice.
The second page is a list of the readings that make up that invoice.

I cannot see how to do this. i tried using groups but they are nesting as they do - what I need is to create a second, independant header/details/footer for the second page.

I hope this makes sense.

Thank you so much for your help

Tim

Passing parameters..., still confused...

Telerik,

I read your article on passing parameters, but I'm still somewhat confused. Here are my questions:

1. Do I need to set a variable on the SQL statement and then set the value of the variable in the parameter dialog and in code? Exampe:

When I create the report, using the query editor, I would create:

SELECT CustomerID, CustomerName from Customer
Where CustomerID = @CustomerID (<-- do I need to create this in my select statement?)

When I create the report to display a report with a selected customer, do I need to use the ReportParameters collection as well to set the value of the above CUSTOMERID?

Do I need to create a ReportParameter collection item in order to set that iten's value in code? Example:

report1.ReportParameters[0].Value = iCustomerID;

report1.Report = report1;

Please advise.

Report viewer (web) has me baffled!

Ok here is the deal Windows Vista, VS 2008, Latest Download (as of this morning) of Report Objects...

Open new project drop the reportViewer on the page hit F5 and all i get is...

    
            Server Error in '/ReportEngine' Application.  
        
            --------------------------------------------------------------------------------  
        
            Configuration Error   
        
            Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.   
        
            Parser Error Message: The 'system.webServer' start tag on line 21 does not match the end tag of 'system.web'. Line 65, position 5.

            Version Information: Microsoft .NET Framework Version:2.0.50727.1434; ASP.NET Version:2.0.50727.1434

This happens with "anything" even opening up one of the examples and running it I have been over the web.config file a million times and it is formated just fine...

Here is where it gets even more mind boggling remove the

<

telerik:ReportViewer ID="ReportViewer1" runat="server" />

from the page and everything works fine I know this is not me as even if i do it manually following the getting started guide everything works fine creating the report class file etc. works like a charm and even in winForms it works but the second i drop and/or add the tag to the page BOOOM! and yes

<%

@ Register assembly="Telerik.ReportViewer.WebForms, Version=2.5.8.519, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" namespace="Telerik.ReportViewer.WebForms" tagprefix="telerik" %>

is registered and dll files are where they should be

Any Ideas, I am about ready to just go back to reporting services and crystal as this is driving me up a wall.

And before you ask I have tried this with and without ajax, on 2.0, 3.0 and 3.5 and no matter what i do it just bombs out
