binding to the text box

[Shobha]

Hi,
I am using OleDbConnection , OleDbAdapter, OledbCommand with parameter
I am having problem with binding the textbox''s text property with the result.

I am sending the code also:

string strOleDb;

strOleDb =

@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\kp\db1.mdb";

OleDbConnection cn = new OleDbConnection();

cn.ConnectionString = strOleDb;

string searchText = "select programs_interest from follow_up_report where no_of_children = ?";

OleDbDataAdapter da = new OleDbDataAdapter(searchText, cn);

OleDbCommand selectCommand = new OleDbCommand(searchText,cn);

da.SelectCommand = selectCommand;

selectCommand.Parameters.AddWithValue("no_of_children", no_of_childrenTextBox.Text);

DataSet ds = new DataSet("follow_up_report");

da.Fill(ds, "follow_up_report");

programs_interestTextBox.DataBindings.Add("Text", ds.Tables["follow_up_report"], "programs_interest");

this is giving the following error :

This causes two bindings in the collection to bind to the same property.
Parameter name: binding

Let me know.
