DataGridView Selected Row Move UP and DOWN

Question

How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an opt

Answer 1

First fill your datagridview,for example you got table with 3 colums

DataTable table = new DataTable();
table.Columns.Add("col1");
table.Columns.Add("col2");
table.Columns.Add("col3");
foreach (var i in yourTablesource(db,list,etc))
{
  table.Rows.Add(i.col1, i.col2, i.col2);
}
datagridview1.DataSource = table;

Then, on button up click

int rowIndex;
private void btnUp_Click(object sender, EventArgs e)
{
    rowIndex = datagridview1.SelectedCells[0].OwningRow.Index;
    DataRow row = table.NewRow();
    row[0] = datagridview1.Rows[rowIndex].Cells[0].Value.ToString();
    row[1] = datagridview1.Rows[rowIndex].Cells[1].Value.ToString();
    row[2] = datagridview1.Rows[rowIndex].Cells[2].Value.ToString();
    if (rowIndex > 0)
    {
        table.Rows.RemoveAt(rowIndex);
        table.Rows.InsertAt(row, rowIndex - 1);
        datagridview1.ClearSelection();
        datagridview1.Rows[rowIndex - 1].Selected = true;
    }
}

Do the same thing for button down, just change row index from rowIndex - 1 to rowindex + 1 in your buttonDown_Click method
