Inserting a new row in datagridview

[Falcon Eyes]

I think you should create a table then
create the desired columns and associated it with the table then add the row for example like the below code

//add a datagridview to your code -> dataGridView1
 
DataTable tabel;
                DataColumn nameColmn;
                DataColumn mobileNoColmn;
                DataColumn homeNoCol;
                DataColumn workNoCol;
                DataColumn emailColmn;

tabel = new DataTable();
            nameColmn = tabel.Columns.Add("Name");
            homeNoCol = tabel.Columns.Add("Home");
            mobileNoColmn = tabel.Columns.Add("Mobile");
            workNoCol = tabel.Columns.Add("Work");
            emailColmn = tabel.Columns.Add("Email");
     
//associate the tabel with datagrid view       
     dataGridView1.DataSource = tabel.DefaultView;

create the row to add

DataRow row = tabel.NewRow();
                        row[nameColmn] = "Falco Eyes";
                        row[homeNoCol] = "123456";
                        row[mobileNoColmn] = "";
                        row[workNoCol] = "";
                        row[emailColmn] = "[email protected]";
                        tabel.Rows.Add(row);
