 Dim newAdapater As SqlDataAdapter
                Dim tbl As New DataTable
                Dim conProc As New SqlConnection
                Dim cmdProc As New SqlCommand
                conProc.ConnectionString = DB
                conProc.Open()
                cmdProc.Connection = conProc
                cmdProc.CommandText = "GetState"
                cmdProc.CommandType = Data.CommandType.StoredProcedure
                cmdProc.Parameters.Add("IsoCodes", Data.SqlDbType.NVarChar, 500).Value = "US"
                newAdapater = New SqlDataAdapter(cmdProc)
                newAdapater.Fill(tbl)
                Me.ComboBoxState.DataSource = tbl

Hi dejandejanovic;

The code looks fine. I tested it in a new project and it worked. I had only changed things with the database I am using such as, connection string,  CommandText, parameter name, parameter value and DisplayMember name and it did fill the ComboBox.

Did you receive any error message?
