Hi
I am having problems in displaying the ReportViewer in WPF. I have followed the sample code but when I try the following steps, the app breaks and throws exceptions.
Steps to reproduce.
1)I added 3 projects to a solution. One was for reports, the other two I picked up from the sample, WpfDemo and Telerik.ReportLibrary.
2)When I ran the Wpf demo it worked fine, and it showed the telerik default report which was in sample.
3)Now I gave ref to my report project in wpf demo and accessed the report from my library.
4)The report was open but in the reportviewer it showed that conn string could not find, because in wpfdemo, the conn string is missing.
5)I added the conn string, and I re run the wpf demo proj. It gave this error:
"'The invocation of the constructor on type 'Telerik.ReportViewer.Wpf.ReportViewer' that matches the specified binding constraints threw an exception.' Line number '42' and line position '14'."
6)Now if I go back to the report from telerik sample and set it using the report property of ReportViewer, the error still persists. It statys dere no matter what I do.

I have uploaded a sample solution which contains the problem.

The download  link for the solution is :

A quick response is highly appreciated.

Dear All,

I have edited that post to be more acurate ...

I have a an applicatio built using PRISM4, RIA service class library, I went through the best practice example and added a SL class library to hold my reports objects. When I tried to add the first report to that class library, I got an error (see attahcment "cl_error_add_report.jpg").

But when I try to add the report to my RIA service .web project I have no problem at all.

What should I do to implement the best practice of having the telerik reports.

Best regards

Hello,

I have a web service which is returing me an array of xml objects in each element. When I create a new report in the Class Project I can see the the method of the web service. I am using the same as my datasource. When I preview the report only the headings show up, no data is shown there.

Any help would be appreciated.

Please post some code to programmatically set a datasource or objectdatasource or whatever it may be for a telerik report.  I can only use a webservice (NOT WCF) that returns a dataset, so I am assuming that I need to set the datasource of the report object programmatically?  I can't see where to do this.  What about report_needdatasource() ?  I can't find any examples, or documentation.  The only documentation just says that you can use different datasources, but not how to use them.

Thanks.

How can i send parameters from silverlight application to reports..

Hi,
I have just downloaded the trial version of the Telerik Reporting, and could use some help,
I would like to be located in a Silverlight application, and to be able to:
 present cross tab information, meanning that I want to feed it with a list of items of class "Item" (each item has a date, location and value ). and have summary rows both by days and by locations - meaning both by columns and by rows.

basically it should look pretty similar to your sales by period report in the example, but the only thing I'm missing there is the option to scroll in case there are too many columns, and to have a freeze column such that the scroll applies only on the details columns and non on the summary columns.

I could not understand how to bind the datasource to any list of items, should I do it pogramatically?

in addition, I tried to creat a silverlight application, and add the classLibrary project with a new report, and I got the message tha the report is not supported by the silverlight runtime...

I hope you would be able to assist me here,...
Thanks

Hi,

We've been using Telerik reporting for a while and now out data has gone bigger. Our telerik report appears to be timing out on our stored procedures. I've set a timeout value on the SqlCommand withing the report but it still seems to timeout ~60 seconds.

Is there any other way of configuring the timeout? I'm guessing since it's WCF based, it can be done within the config file.

Thanks,

Hi, 

I have a Line Chart Setup and it is working great with one ChartSeries. However when I add two sets of data my legend overlaps my labels. Is there any way to prevent this ? My Chart could have 1 set of data or 5 sets of data and my legend should be able to accomdate that. Any help would be appreciated. 

Thanks,

Is a have a report created which shows a basic shape and a textbox with the value of [= Parameters.SomeParameter.Value].

I have code in my Silverlight client which passes the param as  in the RenderBegin event.  This code fires off, but I just receive an error from the Silverlight Report Viewer of:

One or more parameters are not set or have invalid values.

Can I bind to just report parameters?  I am doing this because it is ungodly hard to pass over my objects for the report from the Silverlight client.

How do I set up gridlines so it looks like the data is in a table with lines. Like Excel. I've search the docs and forums but cant find what I'm looking for.

Long week, sorry if this doesn't make sense.
