AutoGenerateColumns= false not working

I am able to set up my datagridview fine.  I use
DgvCalls.AutoGenerateColumns = false;
so that I can programmatically add columns.  The column that I added works fine, however the columns of the datasource are still coming up.  what am I doing wrong?  Below is my code.

Thanks.
//parent table

DaCustomers = new SqlDataAdapter("select * from Customers", conn);

DaCustomers.Fill(data, "Customers");

//child table

DaCalls = new SqlDataAdapter("select * from Calls", conn);

DaCalls.Fill(data, "Calls");

//table with look up values to use in datagridview later

DaTblLkUp = new SqlDataAdapter("select * from tblLkUP", conn);

DaTblLkUp.Fill(data, "tblLkUp");

//relation

DataRelation relation = new DataRelation(" CustomersCalls",

data.Tables["Customers"].Columns["IDCall"],

data.Tables["Calls"].Columns["IDCall"],false);

data.Relations.Add(relation);

//BindSource1

BindSourceCustomers.DataSource = data;

BindSourceCustomers.DataMember = "Customers";

//BindSource2 relation in tables

BindSourceCalls.DataSource = BindSourceCustomers;

BindSourceCalls.DataMember = "CustomersCalls";

//DataGridView shows the related values of the parent table

DgvCalls.DataSource = BindSourceCalls;

DgvCalls.AutoGenerateColumns = false;

//Set up Column with the look up value

One of the colums is called RsnCall.  The main table stores 1, 2, 3 ,4....the second table stores the values to the codes "get info", "appointment", ect

DataGridViewComboBoxColumn Col1 = new DataGridViewComboBoxColumn();


Col1.HeaderText = "Reason Call";

Col1.DataPropertyName = "RsnCall";

Col1.DataSource = data1;

Col1.DisplayMember = "tblLkUp.Name_Lk";

Col1.ValueMember = "tblLkUp.ID_Lk";


Col1.FlatStyle = FlatStyle.Flat;



DgvCalls.Columns.Insert(1, Col1);

What am I doing wrong????

Well,

I tried your way and it's true, but try to invert your two lines:

DgvCalls.AutoGenerateColumns = false;
DgvCalls.DataSource = BindSourceCalls;

Worked on mine!
