Again I recalculate that and try to set in same cell in bounded column time the value not changing so I try to clear the cell value before set a value to it. </p> <pre><code> private void gridView1_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e) { // % to amt object obj = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountPercentage"]) == DBNull.Value ? 0 : (gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountPercentage"])); decimal a = Convert.ToDecimal(obj); if (a &gt; 0) { gridColumn1.UnboundType = DevExpress.Data.UnboundColumnType.Decimal; gridColumn1.UnboundExpression = "[UnitPrice] * ([DiscountPercentage] / 100.0)"; } // amt to % object dm = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountAmount"]) == DBNull.Value ? 0 : (gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountAmount"])); decimal a1 = Convert.ToDecimal(dm); if (a1 &gt; 0) { gridColumn2.UnboundType = DevExpress.Data.UnboundColumnType.Decimal; gridColumn2.UnboundExpression = "Round(([DiscountAmount] / [UnitPrice]) * 100.0, 2)"; } } private void gridView1_FocusedRowChanged(object sender, DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e) { // % to amt object obj = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountPercentage"]) == DBNull.Value ? 0 : (gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountPercentage"])); decimal a = Convert.ToDecimal(obj); if (a &gt; 0) { object obj2 = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["gridColumn1"]); int aa = Convert.ToInt32(obj2); gridView1.SetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountAmount"], aa); } // amt to % object dm = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountAmount"]) == DBNull.Value ? 0 : (gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountAmount"])); decimal a1 = Convert.ToDecimal(dm); if (a1 &gt; 0) { object obj3 = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["gridColumn2"]); int aa2 = Convert.ToInt32(obj3); gridView1.SetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["DiscountPercentage"], aa2); } } </code></pre> <p>Thanks in advance.</p>
