Best method to access data for Winform

I am grappling with the fact that someone told me to use the Data controls that are provided with the .Net framework. These controls seem to be easy to start with and use. I am wondering if it is really efficient to use these controls when you need several different datasets for only 1 form. For instance if I wanted to populate 3 different comboboxes with data from a database I would have to add 3 different data adapters and 3 different datasets. Then I would need a data adapter and dataset control for the data grid. I am concerned that there might be a lot of overhead with adding several data adapters and data set controls to one form. Also, the queries will be dynamic based on what the user selects. Should I avoid the controls in this situation?

Why couldn't you use one dataAdapter and fill different datasets from different database tables? You can specify the particular table within the dataset to deal with a datagrid or whatever control you wanted to use. Unless you need to connect to multiple servers you can use 1 dataAdapter. Even if you need to connect to multiple servers you can keep redefining the connection string for that dataAdapter. So you can change your sql select statement to specify different tables, then call the fill method specifying a particular table...DataAdapter.Fill(DataSet,"tablename"). Then bind that table to the datagrid and then you can use all the .Net methods to update, insert, etc... hope this answers your question.
