Thanks Challen I will try it. Only other improtant thing i can mentioned is that my solution consist on huge number of projects.so it might be problem in initializing object datasources.Kamran Shahid Senior Software Engineer/Analyst (MCP,MCAD,MCSD.NET,MCTS,MCPD.net[web])

Challen What i have found that it is because of so much references i have in my We application projects.Atleast one or two projects are letting this during the binding of object datasource dropdown list from which i can use my dataset/datatable I have done some workaround to temprorary let the report away but will look into the matter later.Thanks Kamran Shahid Senior Software Engineer/Analyst (MCP,MCAD,MCSD.NET,MCTS,MCPD.net[web])
