I got a problem, 'cause I got one DataGridView1 and when I read the database records each line should be added in a Column of my DataGridView1. My example DataGridView1 has the columns Column1, Column2, ... Column10 and when sweeping the bank I have the records: 1,2,3 ... 20 in which the DataGridView1 should be fed as in the image below, does anyone have any suggestions as to how I can do this?

And this would be my table in the database where I already do a query and get the column value FICCOD I do the whole conversion and then add it to the grid!

The code I am doing is this below more in some situations it does not feed all the bank records, if for example I have 15 records it will feed only the first 10, only be working if the database is a number of records that can be divided into 10-record intervals "closed".

private void alimentaGrid()
{           
    DataGridViewListaMesa.Rows.Clear();

    DataSet ds = Engebuilder.Library.LDataAccess.GetDataSet("SELECT FICCOD FROM FICHA");
    int contador = 0;

    ArrayList ListaMesa = new ArrayList();

    foreach(DataRow row in ds.Tables[0].Rows)
    {               
        Int64 codigo = Int64.Parse(row["FICCOD"].ToString().Trim());

        ListaMesa.Add(codigo);  
        contador += 1;

        if(contador.Equals(10))
        {
            string Column1 = String.Empty;
            string Column2 = String.Empty;
            string Column3 = String.Empty;
            string Column4 = String.Empty;
            string Column5 = String.Empty;
            string Column6 = String.Empty;
            string Column7 = String.Empty;
            string Column8 = String.Empty;
            string Column9 = String.Empty;
            string Column10 = String.Empty;

            for(int i = 0; i < ListaMesa.Count; i++)
            {
                Column1 = ListaMesa[0].ToString().Trim();
                Column2 = ListaMesa[1].ToString().Trim();
                Column3 = ListaMesa[2].ToString().Trim();
                Column4 = ListaMesa[3].ToString().Trim();
                Column5 = ListaMesa[4].ToString().Trim();
                Column6 = ListaMesa[5].ToString().Trim();
                Column7 = ListaMesa[6].ToString().Trim();
                Column8 = ListaMesa[7].ToString().Trim();
                Column9 = ListaMesa[8].ToString().Trim();
                Column10 = ListaMesa[9].ToString().Trim();
            }

            DataGridViewListaMesa.Rows.Add(Column1, Column2, Column3, Column4, Column5, Column6, Column7, Column8, Column9, Column10);

            ListaMesa.Clear();
            contador = 0;
        }           
    }
}

You want to swap rows and columns this? I mean, turn rows (records) into columns and columns into rows?

It would be basically that, as being in the image the value of each column corresponds to a row in the database.

You would have an example of your ai database?

Guys I managed to solve my problem the following way as being just below, I know it got a little gambiara :(

If anyone has any better suggestions I’d appreciate it!

private void alimentaGrid()
{
    DataGridViewListaMesa.Rows.Clear();

    DataSet ds = Engebuilder.Library.LDataAccess.GetDataSet("SELECT FICCOD FROM FICHA");
    int contador = 0;
    int aux = 0;
    int QtdTotal = ds.Tables[0].Rows.Count;
    int resto = QtdTotal;

    ArrayList ListaMesa = new ArrayList();

    foreach (DataRow row in ds.Tables[0].Rows)
    {
        Int64 codigo = Int64.Parse(row["FICCOD"].ToString().Trim());

        ListaMesa.Add(codigo);
        contador += 1;

        if (resto >= 10)
        {
            if (contador.Equals(10))
            {
                string Column1 = String.Empty;
                string Column2 = String.Empty;
                string Column3 = String.Empty;
