You can use the CellMouseEnter and CellMouseLeave to track the row number that the mouse is currently hovering over.

Not tested, but I think you can do the following: dataGrid.Rows[index].Selected = true; or you could do the following (but again: not tested): dataGrid.SelectedRows.Clear(); foreach(DataGridViewRow row in dataGrid.Rows) { if(YOUR CONDITION) row.Selected = true; }

You need to loop through the rows in the datagridview and then compare values of columns 7 and 10 on each row. Try this: foreach (DataGridViewRow row in vendorsDataGridView.Rows) if (Convert.ToInt32(row.Cells[7].Value) < Convert.ToInt32(row.Cells[10].Value)) { row.DefaultCellStyle.BackColor = Color.Red; }
You can do: DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone(); row.Cells[0].Value = “XYZ”; row.Cells[1].Value = 50.2; yourDataGridView.Rows.Add(row); or: DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone(); row.Cells[“Column2”].Value = “XYZ”; row.Cells[“Column6”].Value = 50.2; yourDataGridView.Rows.Add(row); Another way: this.dataGridView1.Rows.Add(“five”, “six”, “seven”,”eight”); this.dataGridView1.Rows.Insert(0, “one”, “two”, “three”, “four”); From: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rows.aspx
