Data Adapter is basically a class that represents a set of SQL commands with a database connection property, the fill method is used for updating data source There are different types of Data Adapter for different datasource in, Sql Data Adapter, Ole Db Data Adapter, Oracle Data Adapter etc.

But the base class implementations are same for all Data Adapter class.

Thanks Hi, Can you verify if the Category ID is the primary column in your database table? One option is to set the primary column in the table and regenerate the dataset.
