–>ContractClass_MY Object Not Initialize Error Why ?
Can you show us how you’ve associated ContractClass_MY with your data provider?
My Issue is When i generate report from Visual Studio 2010 its works fine. But when i added that report to Menu Item and Open/Run from Front End it gives me error. When i debug that code and found that its gives me error from Contract Class object not Initialized. Please help me for this case. Thanks in Advanced.
If you don’t want to tell us more your code, at least split the statement to two parts and check whet you get before applying “as ContractClass_MY”.
→ Inside ContractClass_MY class

You’re trying to convert the contract to ContractClass_MY, but your contract is Dev_PurchaseInvoice_Contract, which isn’t compatible and therefore the case can’t work.
Throw away SRSReportParameterAttribute on your controller class; it has no effect there.
