I have a pie graph and want to map its items to two values in the detail section data.  For example,  if the report data has two columns COLUMN_ONE and COLUMN_TWO, how can I map two slices of a pie graph to those columns?  Do I need to do it programmatically?

When I attempt to use the technique described  at http://www.telerik.com/help/reporting/faq-combine-values2.html I get an error saying "Unable to cast object of type "DataObject" to type "System.Data.DataRow".  So if I have a pie chart in a detail section, how can I assign its items values from the current DataRow?

Hi everyone,
Can anyone tell me how to change the numeric format??

In my case, I want to change the -ve sign into ( ), and have the digit grouping when the number reach thousands.(If anyone familiar, it's like the Excel format, changing the negative format)
I can change the -ve sign into ( ) using the IIf() function. E.g: = IIf(Fields.creditAmount>0, Fields.creditAmount, "(" + (Fields.debitAmount) + ")") . So the result which I get satisfy me. If the number is larger than 0 (which is not a negative number) , it display 1123.45. 
If  the result is smaller than 0 (which is a negative number), it display (1123.45). So far the result, fullfill my first requirement.

However, by doing the above stated (using the IIF( ) function), I could not manage to get the digit grouping. How can I do that? I try using the {0:N2},  but the result won't display according to the format digit.

Can anyOne help me? I appreciate any opinion. Thank you very much.

I have white space on the right of my graph as seen in the image attached to this post.  Anyone know how to get rid of this?

EDIT: I fixed this

I found in the system requirement section in this Web that the requirement of using Telerick components in Windows applications does not apply to Windows 98.

Question:
1. Application writen by Telerick components cannot work under Windows 98 Second Edition, even dotNet 2.0 is installed?

Urgent. Pls. help.

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?

 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
