c# - Why foreach loop fails at last row of gridview? -

i have put code color background of gridview cell# 14 if cell's text != "nbsp;" , work except last row. doesn't color last row isn't equal "nbsp;"

protected void grdviewcases_rowdatabound(object sender, gridviewroweventargs e)     {         if (e.row.rowtype == datacontrolrowtype.datarow)          {             foreach (gridviewrow gr in grdviewcases.rows)             {                 if (gr.cells[14].text != " ")                 {                     gr.cells[14].backcolor = color.red; ;                     gr.cells[14].forecolor = color.whitesmoke;                 }             }         }     } 

you need not loop rows in rowdatabound event, may use e object reference each row

protected void grdviewcases_rowdatabound(object sender, gridviewroweventargs e)     {         if (e.row.rowtype == datacontrolrowtype.datarow)          {             if (e.row.cells[14].text != " ")             {                 e.row.cells[14].backcolor = color.red; ;                 e.row.cells[14].forecolor = color.whitesmoke;             }         }     }
