I'm using ReportViewer 9.0 in asp.net 3.5 using VS 2008. When executing the form, it retrieve data from SP and got the result in DataTable. The report display error
The Hidden expression for the table ‘table1’ contains an error: Input string was not in a correct format.
What cause this error ?

It looks like you are setting a hidden formula for a group or cell in the report and in the formula, you are expecting integer value in a parse/ctype casting where the value you are getting is string. Please post the expression you are using .
