C# 遍历 DataGridView 并更改行颜色

Question

我有一个由多行和多列组成的数据 GridView 。我想遍历每一行并检查特定列的内容。如果该列包含单词“NO”，我想将整行的前景色更改为红色。到目前为止，这是对一些代码的尝试，但肯定行不通，开始怀疑我是否需要遍历每个单元格？

代码:

foreach (DataGridViewRow dgvr in dataGridView1.Rows)
        {
            if (dgvr.Cells["FollowedUp"].Value.ToString() == ("No"))
            {
                dgvr.DefaultCellStyle.ForeColor = Color.Red;
            }
        }

连接OnRowDataBound事件然后做事

ASPX(网格):

    <asp:.... OnRowDataBound="RowDataBound"..../>

代码隐藏:

    protected void RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowIndex == -1)
        {
            return;
        }

        if(e.Row.Cells[YOUR_COLUMN_INDEX].Text=="NO"){
             e.Row.BackColor=Color.Red;   
        }
    }

对于 WinForms:

hook the **DataBindingComplete** event and do stuff in it:

     private void dataGridView1_DataBindingComplete(object sender, 
                       DataGridViewBindingCompleteEventArgs e)
    {
        if (e.ListChangedType != ListChangedType.ItemDeleted)
        {
            DataGridViewCellStyle red = dataGridView1.DefaultCellStyle.Clone();
            red.BackColor=Color.Red;

            foreach (DataGridViewRow r in dataGridView1.Rows)
            {
                if (r.Cells["FollowedUp"].Value.ToString()
                       .ToUpper().Contains("NO"))
                {
                    r.DefaultCellStyle = red;
                }
            }
        }
    }
