Solution 1

The datatable dt is not a object reference from ds.Tables[0].
In your code, you created dt as a new datatable, and created the two columns, but the table is never filled.

Solution 3

you are trying to assign a empty datatable to bindingsource.

try like this.

C#

tblnamesbs.DataSource = dt;
tblnamesbs.DataSource = ds.Tables[0];
this.textBox1.DataBindings.Add("Text", this.tblnamesbs, "firstname", true);
this.textBox2.DataBindings.Add("Text", this.tblnamesbs, "lastname", true);

sample:

C#

OleDbDataAdapter dAdapter = new OleDbDataAdapter("select * from oui_table", "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=bd.mdb");
dAdapter.Fill(ds, "t1");

this.dataGridView1.DataSource = ds.Tables["t1"];

this.textBox1.DataBindings.Add(new Binding("text", ds.Tables["t1"], "id_oui"));
