this my my code if (dataGridView1.Rows[e.RowIndex].Cells[1].Value != null) { string cellValue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString(); if (!string.IsNullOrEmpty(cellValue)) { _bar = cellValue; PopulateColumns(); dataGridView1.Rows[e.RowIndex].Cells[2].Value = _proname; dataGridView1.Rows[e.RowIndex].Cells[3].Value = _price; dataGridView1.Rows[e.RowIndex].Cells[4].Value = _unit; } } i use PopulateColumns(); to access data from data table and pass it to the grid view where it equal dataGridView1.Rows[e.RowIndex].Cells[1].Value . when i use break-point it works correct if i stop break point it repeat the same data in each row despite the value of dataGridView1.Rows[e.RowIndex].Cells[1].Value is not the same ?
