Checkbox zooming

Currently i'm working in WF-GridControl, implemented the zooming concept to checkbox control. Checkbox rectangle will be zoomed properly for Screen Resoultion(1920*1080) but for other resolution it is not working, please suggest me how can I resolve,

 renderer = this.groupingGrid.TableControl.CellRenderers[GridCellTypeName.CheckBox] as GridCheckBoxCellRenderer;
        //for maintaining the original size of the checkBox
        SavedCheckBoxSize = renderer.CheckBoxSize;
            renderer.CheckBoxSize = new Size((int)(SavedCheckBoxSize.Width * usePercent), (int)(SavedCheckBoxSize.Height * usePercent));

and i'm tried with sample level to resolve resolution problem.

this.gridGroupingControl1.TableControl.DpiAware = true;
        this.AutoScaleMode = AutoScaleMode.Dpi;

Please suggest me your ideas, Thanks in Advance.
