根据条件动态改变GridView某行或某个单元格的背景色

C#代码

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        // 设置行的背景颜色
        if (e.Row.Cells[1].Text == "0111")
        {
            e.Row.BackColor = System.Drawing.Color.Red;
        }
        else
        {
            e.Row.BackColor = System.Drawing.Color.Gray;
        }
        // 设置单元格的颜色
        if (e.Row.Cells[1].Text == "0111")
        {
            e.Row.Cells[1].BackColor = System.Drawing.Color.Green;
        }
      }
