Does a report viewer require a report get its data from a telerik SqlDataSource (as opposed to the microsoft version)?  I am currently using an asp SqlDataSource to provide information to my report.  The report works fine when rendered manually using ReportProcessor.RenderReport() but doesn't render correctly when put into a report viewer.  When put into a report viewer, i get this error:

An error has occured while processing Report '':
The expression contains object 'Test_Type' that is not defined in the current context.

Hello,

I want to create a report viewer parameter combo box but can't seem to figure out a certain part of doing it.  When I'm creating the report parameter, how do I choose the values for the combo box?  I.e. I need a combo box where the user can choose between two values which are "Summary" and "Detailed".  I tried putting those values into an array and assigning it to the AvailableValues.DataSource but that didn't work because it then asks me to fill DisplayMember and ValueMember (which is a problem because an Array doesn't have column names, which is what DisplayMember and ValueMember want).  I also can't find a single example of how to do this.  Anyone know how to do this?

how can we give multiple filters  using below coding iam already given data filteroperator in 

now how can i give another data.filteroperator for that same form

 Telerik.Reporting.Data.Filter f12 = new Telerik.Reporting.Data.Filter();
            f12.Expression = "=Fields.courseid";
            f12.Operator = Telerik.Reporting.Data.FilterOperator.In;
            f12.Value = "=Parameters.Courses";
            rp2.UI.AvailableValues.Filters.Add(f12);

I also am having a problem with the ReportViewer not working after having moved my project into VS2010 and .NET 4.0.  The ReportViewer shows no data for my drop down controls and no chart.  I have added the <handler> to web.config that I found in another post:

I am currently running Telerik Reporting Q3 2008 SP2 (v2.9.9.202).  Would updating to a newer version help?
Thanks.  Dan

How can we use stored procedure returns mutiple result set in telerik reproting? First result set returns company name and address that goes in report header section, second result set returns detailed rows for report. Any examples would be much appreciated. 

hanks for your time.

Hi: In another thread it became clear to me that I could not dynamically load an html table and render it using the html textbox (because the textbox does not support it). I am trying a different approach here and am running into a problem. I have a report that is about 10 pages long. On page one ONLY, I want to display a Telerik table with some values in it. Obviously, if I put the table in the details section it gets replicated to every page. I tried dragging a table into the page header, where I could put conditional formatting in to say if =PageNumber > 1 visible = false. This works for a textbox but I cannot drag a table to the page header -- it appears as though the Telerik reporting tool does not support it.

What is an approach to accomplish what I need to accomplish? Thanks!

i notice the new dll version is 4.0.10.423

does this mean it is a .net 4 compile? is there a seperate 3.5 compile ?

i have upgraded a server to this latest version but when running a report the reportviewer page reports reportviewer not found.

I am creating a report which has a multivalue parameter user. It gets all the users from the database. The report also uses a query directly similar to "select col1, col2, col3
from table1
where (col1 in (@user)) and .....

When I run this report with the user parameter set to Multivalue I get the following error

An error has occured while processing Report:
Failed to convert parameter value from a Object[] to a String.
---------------InnerException---------------------------
Object must implement IConvertible

The report runs fine if the @user is not set to multivalue. The type on @user is a string.

Please advise.
Thanks for your time in advance
