BindingSource equivalent in C#.NET?

[mcupito]

Hello, all.

I'm attempting to create a search box using C#.NET. Thus far, I've got this code:

 protected void SearchBox_TextChanged(object sender, EventArgs e)
        {
            DataView DV = new DataView(dbDataSet);
            DV.RowFilter = string.Format("CourseNum LIKE '%(0)%'", SearchBox.Text);
            dataGridView1.DataSource = DV;


        }

        protected void Button1_Click(object sender, EventArgs e)
        {    
             string error = "Error";
             string constring = ConfigurationManager.ConnectionStrings["MyDB"].ConnectionString; 
            SqlConnection conDataBase = new SqlConnection(constring);
            SqlCommand cmdDataBase = new SqlCommand(" select * from ASPNETDB.CourseNum ;", conDataBase);

            try{
                SqlDataAdapter sda = new SqlDataAdapter();
                sda.SelectCommand = cmdDataBase;
                DataTable dbdataset = new DataTable();
                sda.Fill(dbdataset);
                BindingSource bsource = new BindingSource();

                bsource.DataSource = dbdataset;
                dataGridView1.DataSource = bsource;
                sda.Update(dbdataset);
            }catch(Exception ex){

                ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + error + "');", true);
            }

In C#.NET, there is no such thing as "BindingSou rce" so I am kind of stuck in a rut. I deleted the Gridview and replaced it with a FormView, however I am not sure where to go from here as far as the code goes. Does anyone have any guidance?

Thanks.
