System.Data.DataRowView

Why when I execute this code, my DropDownList is populated with the value
"System.Data.DataRowView"????

See the code:
cmdCommand.CommandText = "SELECT UsuaNome FROM usuarios"

dapAdapter.SelectCommand = cmdCommand 'dapAdapter is a DataAdapter
dapAdapter.Fill(dtsDataSet, "Usuarios")

drpLigaAten.DataSource = dttUsuarios 'dttUsuarios is a DataTable
drpLigaAten.DataBind() 'drpLigaAten is a DropDownList
Thank's

André,
When binding to a DataTable, you need to set the DataTextField &
DataValueField properties, to the field to display & the field to return
respectively.

Hope this helps
Jay

André,
Just set the properties to the names of the fields.

Something like:
drpLigaAten.DataSource = dttUsuarios 'dttUsuarios is a DataTable drpLigaAten.DataTextField = "Field1"
drpLigaAten.DataValueField = "Field2" drpLigaAten.DataBind() 'drpLigaAten is a DropDownList
