在datagridview中rowpostpaint事件中如下寫法：

privatevoiddatagridviewapplydetail_rowpostpaint(objectsender,datagridviewrowpostpainteventargse)

{

rectanglerectangle=newrectangle(e.rowbounds.location.x,e.rowbounds.location.y,datagridviewapplydetail.rowheaderswidth-4,e.rowbounds.height);

textrenderer.drawtext(e.graphics,(e.rowindex+1).tostring(),datagridviewapplydetail.rowheadersdefaultcellstyle.font,rectangle,

datagridviewapplydetail.rowheadersdefaultcellstyle.forecolor,

textformatflags.verticalcenter|textformatflags.right);

}
