Hello All,

I have implemented SQL Server session state in my application however I am
having some problems. Simple objects stored in Session state are fine and are
handled by .NET, however when I try to store gridview control in session state I am not able to figure out exactly what I have to
do to serialize and deserialize the object.

I am going thru below error

VB

Server Error in '/' Application.
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

hi rohu123,
Gridview or most of the controls are not serializable. Class or object should have Serializable attribute in order to save or add it on the Session state.

You should not be storing UI controls in the session state. Instead, store the data which is being shown in that control (I guess that is either a DataTable or a List<YourModelObject>, both of which should be serialisable if you mark your object type as such).
