为什么foreach循环在gridview的最后一行失败？

Question

如果单元格的文字！=＆＃34; nbsp;＆＃34;除最后一行外，它确实有效。它没有为最后一行着色，即使它不等于＆＃34; nbsp;＆＃34;

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;
                }
            }
        }
    }

你不需要在RowDataBound事件中循环行，你可以只使用e对象来引用每一行

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;
            }
        }
    }
