Get the DataTable. Bind the DataTable. What's "not working"? -

You'd better put some your code here. It would help others to solve your issue. -

Puedes hacerlo así.

YourTableAdapter  yourTableAdapter = new YourTableAdapter();
YourTypedDataSetClass.YourTableDataTable yourTable = yourTableAdapter .GetData();
dropdownlist1.DataTextField = "TextFieldInYourTable";
dropdownlist1.DataValueField = "ValueFieldInYourTable";
dropdownlist1.DataSource = yourTable;

He used typed datasets, not LINQ. - kirin yao

Linq could be used to query data from typed dataset and it makes it easy. Please read this msdn.microsoft.com/en-us/library/bb399358.aspx - Adil

Of course he can use LINQ to DataSet, but there is no any XxxDataContext class to make use of. You should edit your answer. BTW, I'm not the one down voting your answer. - kirin yao

puedes probar con este codigo

TypedDataSet typedDataSet  = ....;
dropdownlist1.DataTextField = typedDataSet.YourTable.YourColumn1;
dropdownlist1.DataValueField = typedDataSet.YourTable.YourColumn2;
dropdownlist1.DataSource = typedDataSet;
