Here's a code snippet I just worked out this afternoon which should produces visible row numbers: int hpadding = 40; Graphics graphic = gridview.CreateGraphics(); gridview.RowHeadersWidth = ( int )graphic.MeasureString(gridview.RowCount.ToString( N0 ) gridview.Font).Width + hpadding ; graphic.Dispose(); gridview.RowHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment .MiddleRight ; foreach ( DataGridViewRow dr in gridview.Rows) { dr.HeaderCell.ValueType = System. Type .GetType( System.String ); dr.HeaderCell.Value = (dr.Index + 1).ToString( N0 ); } I hope it helps. (warning: I'm really a VB.Net kind of guy so this may not be an optimal solution)

Try this code.................. private void dataGridView1_RowValidated( object sender DataGridViewCellEventArgs e) { DataGridView Gview = sender as DataGridView ; if ( null != Gview) { Gview.Rows[e.RowIndex].HeaderCell.Value = Convert .ToString(dataGridView1.CurrentRow.Index+1); } }

Hi Resmy You can inherit DataGridViewRowHeaderCell and override it's Value member to be equal RowIndex + 1 You will need to set HeaderCell of every row to your custom type. You can do that in RowsAdded event of the DataGridView Please mark this post as an answer if it helps you Nir
