Answer 1

You can instantiate a DataTable and populate it from your dataGridView1 control:

        DataTable table = new DataTable("Customers");
        // copy the correct structure from datagridview to the table
        foreach (DataGridViewColumn column in dataGridView1.Columns)
        {
            table.Columns.Add(column.Name, typeof(string));
        }

        // populate the datatable from datagridview
        for (int rowIndex = 0; rowIndex < dataGridView1.Rows.Count; rowIndex++)
        {
            table.Rows.Add();
            for (int columnIndex = 0; columnIndex < dataGridView1.Columns.Count; columnIndex++)
            {
                table.Rows[rowIndex][columnIndex] = dataGridView1[rowIndex, columnIndex].Value;
            }
        }

then continue with the rest of your code:

    DataSet ds = new DataSet();
    ds.Tables.Add(table);
    ds.WriteXml("d:/newXML.xml", System.Data.XmlWriteMode.IgnoreSchema);
