Preview Problen in StiWebDesigner

[suhas.tjs]

hi all
i am trying to preview a report, which has a data band connected to a table.
i have an aspx application where i am assigning Datasource and using StiWebDesgner1.Design(Report) i have created the above report.
Now in designer im trying to preview the data in html but i am getting following error.

Compilation Error in Report

File Name Line, Column Error Number Error Text
c:\Users\suhastj\AppData\Local\Temp\r5ayqzfh.0.cs 118, 47 CS0246 The type or namespace name 'Default3' could not be found (are you missing a using directive or an assembly reference?)

i have a sql server data source. so can any buddy tell me how to assign data set in the StiWebDesigner1_GetPreviewDataSet Event so that i can preview data in designer. its urgent

Thanks in advance.
