Crystal Reports - Accessing IGraphObject properties at runtime

I am using Visual Studio 2008 and Crystal Report开发者_StackOverflow社区s that is shipped with it. I would like to set certain properties of a chart such as Chart Title at Runtime. I have tried via ChartObject but there are only limited properties such as top, width, height etc. and not the properties I'm interested in. I included "craxddrt.dll" in my solution which provides IGraphObject but am obviously trying to cast the wrong class with it as it returns an invalid object reference...

(myReportDocument.ReportDefinition.ReportObjects[0] as IGraphObject).Title

Any help in retrieving the chart properties would be much appreciated...

thanks,

Paul

Instead of trying to set the chart title at runtime, set it to be blank and display a Crystal formula in the same place.
