How to solve the Row alignment behavior which changes anonymously

this.pivotGridControl1.InternalGrid.PrepareRenderCell += (s, eventArgs) =>

{

if (eventArgs.Cell.RowIndex > (pivotGridControl1.PivotColumns.Count - (this.pivotGridControl1.ShowCalculationsAsColumns ? 0: 1) - (this.pivotGridControl1.PivotCalculations.Count == 1 ? 1:0) + (!this.pivotGridControl1.ShowCalculationsAsColumns && this.pivotGridControl1.PivotCalculations.Count==1? 1:0 ) ))

{

//For Row headers and value cells

eventArgs.Style.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;

}

else if (eventArgs.Style.CellType.Equals("ExpanderCell"))

{

//For Column Headers that has only expander cells

(eventArgs.Style as GridStyleInfo).HorizontalAlignment = System.Windows.HorizontalAlignment.Center;

}

else

{

//For Column Headers that has static cells

eventArgs.Style.HorizontalAlignment = System.Windows.HorizontalAlignment.Right;

}

};
