Question

I have two DataGirdViews. I want to select rows from right DataGridView and pass them to the left one.

The right one has 4 columns. In the left grid, I only defined one new column and I want to display this column only. This column is one of columns of the right one, say column[2].
I am stuck here, not sure how to pass the rows?

My incompleted code(maybe error, untested):

 private void btnAdd_Click(object sender, EventArgs e)
    {
        try
        {
            if (dgRight.CurrentRow != null)
            {
                DataRowView currentDataRowView = (DataRowView)dgRight.CurrentRow.DataBoundItem;
                foreach (DataGridViewRow row in dgRight.Rows)
                {
                    DataGridViewCheckBoxCell check = row.Cells[0] as DataGridViewCheckBoxCell;
                    if (check.Value != null)
                    {
                        if ((bool)check.Value)
                        {
                            //this row has a checkBox set to true (tick is added)
                            //add this row to dataTable ...
                            DataRow myRow = (row.DataBoundItem as DataRowView).Row;
                            DataRow dr = dt.NewRow();

                            if (!dt.Columns.Contains("ID"))
                            {
                                datatableRight.Columns.Add("ID", typeof(int));
                                datatableRight.Columns.Add("col1", typeof(string));
                                datatableRight.Columns.Add("col2", typeof(string));
                                datatableRight.Columns.Add("col3", typeof(string));
                                DataColumn[] keyColumns = new DataColumn[1];
                                keyColumns[0] = datatableRight.Columns["ID"];
                                datatableRight.PrimaryKey = keyColumns;
                            }

                            dr["ID"] = myRow["ID"];
                            dr["col1"] = myRow["col1"];
                            dr["col2"] = myRow["col2"];
                            dr["col3"] = myRow["col3"];

                            if (!datatableRight.Rows.Contains(dr[0]))
                            {
                                datatableRight.Rows.Add(dr);
                            }
                        }
                    }

                }
                dgLeft.DataSource = datatableRight;
                datLeft = datatableRight.Copy();

            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

Thanks.

Simple use two dataTables with same schema to bind these grids, then Move the rows in DataTables.
