Follow What does “DataView is not marked as serializable in System.data” mean?[^].

It means that the object you want to store (DataView) isn't marked with a SerializableAttribute.

Now, the reason you're getting this error with ViewState and not with Session is because the ViewState is always serialized but that's not necessarily true of Session. In-Process sessions are stored in the server's memory and require no serialization. SQLServer sessions have to be serialized for storage in a database.

So, anytime you want to store an object in the ViewState (or a serialized Session), it must be marked with a SerializableAttribute.

and dataview in viewstate[^]

instead of putting dataview to viewstate, put dataview.Table to viewstate. It'll resolve your problem.

C#
DataView dv = ds.Tables[0].DefaultView;
ViewState.Add("key", dv.Table);

Solution 1

instead of putting dataview to viewstate, put dataview.Table to viewstate.
Also the code shouldfollow as below if there is a syntax error.
ViewState["ViewStatedtName"] = dvData;

If the above solution doesn't resolve post ur error message .
