Como preencher um dropdown list com dados do BD MySQL ?

Galera, estou tentando popular um combo com os estados salvos em uma tabela do BD.

Estou usando o visual studio. Web form - VB.NET.

Tentei através da ferramenta já presente no dropdown "choose data source". Aparentemente fiz tudo direitinho.

Na hora de testar a query funcionou e tudo mais, mas quando eu dou finish, no dropdown aparece (databound)

e ao abrir a pagina atraves do navegador aparece o seguinte erro:

Server Error in '/Workbook' Application.--------------------------------------------------------------------------------
