I have a counter that is retuned to a Main form and i would like to populate a datagridvierw and a text box resulting from this counter with results from 2 tables (Customer and contact tables), how can i do this? is it possible? Currently i have a view (vwCustomersandContacts that has customer names, address and the contacts for that customer) that returns me the records that is = to counter but its causing me a headache when trying to delete a row from the datagridview so i though if i use a table instead of a view would be simplier
using (frmSearchCustomer form = new frmSearchCustomer())

            {

                if (form.ShowDialog() == DialogResult.OK)

                {

                    System.Data.SqlClient.SqlConnection cnn = new System.Data.SqlClient.SqlConnection();

                    conn = new SqlConnection(@"Data Source=<SQLInstance;Initial Catalog=<Database>;Integrated Security=True");

                    comm = new SqlCommand("SELECT * FROM vwCustomersandContacts WHERE CustomerCounter = " + form.Counter + "");

                    da = new SqlDataAdapter();

                    ds = new DataSet();

                    comm.Connection = conn;

                    da.SelectCommand = comm;

                    datagridview1.AutoGenerateColumns = false;

                    //Datagridview1 column1

                    var col1 = new DataGridViewColumn();

                    col1.DataPropertyName = "FirstName";

                    col1.Name = "First Name";

                    var cell1 = new DataGridViewTextBoxCell();

                    col1.CellTemplate = cell1;

                    datagridview1.Columns.Add(col1);

                    //Datagridview1 column2

                    var col2 = new DataGridViewColumn();

                    col2.DataPropertyName = "LastName";

                    col2.Name = "Last Name";

                    var cell2 = new DataGridViewTextBoxCell();

                    col2.CellTemplate = cell2;

                    datagridview1.Columns.Add(col2);

                    //Datagridview1 column3

                    var col3 = new DataGridViewColumn();

                    col3.DataPropertyName = "Telephone";

                    col3.Name = "Telephone";

                    var cell3 = new DataGridViewTextBoxCell();

                    col3.CellTemplate = cell3;

                    datagridview1.Columns.Add(col3);

                    //Datagridview1 column4

                    var col4 = new DataGridViewColumn();

                    col4.DataPropertyName = "Mobile";

                    col4.Name = "Mobile";

                    var cell4 = new DataGridViewTextBoxCell();

                    col4.CellTemplate = cell4;

                    datagridview1.Columns.Add(col4);

                    //Datagridview1 column5

                    var col5 = new DataGridViewColumn();

                    col5.DataPropertyName = "Department";

                    col5.Name = "Department";

                    var cell5 = new DataGridViewTextBoxCell();

                    col5.CellTemplate = cell5;

                    datagridview1.Columns.Add(col5);

                    //Datagridview1 column6

                    var col6 = new DataGridViewColumn();

                    col6.DataPropertyName = "Position";

                    col6.Name = "Position";

                    var cell6 = new DataGridViewTextBoxCell();

                    col6.CellTemplate = cell6;

                    datagridview1.Columns.Add(col6);

                    //Datagridview1 Column7

                    var col7 = new DataGridViewColumn();

                    col7.DataPropertyName = "VIP";

                    col7.Name = "VIP";

                    var cell7 = new DataGridViewTextBoxCell();

                    datagridview1.Columns.Add(col7);
 

                    da.Fill(ds);

                    datagridview1.DataSource = ds.Tables[0];
 

                    System.Data.SqlClient.SqlDataAdapter recordAdp = new System.Data.SqlClient.SqlDataAdapter();

                    conn.Open();

                    recordAdp.SelectCommand = comm;

                    SqlDataReader reader = comm.ExecuteReader();

                    while (reader.Read())

                    {

                        txtCustomerName.Text = (String)reader["CustomerName"];

I noticed you datagridview1 doesn't have a DataMember

datagridview1.DataMember = "";

Here is an article that might help

A little more explanation of what is going wrong would be good.
