GridView的RowDataBound函数

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // 获取当前行的数据
        DataRowView rowView = e.Row.DataItem as DataRowView;

        // 判断数据中的某个值是否满足条件
        if (rowView["SomeColumn"].ToString() == "SomeValue")
        {
            // 改变当前行的背景色
            e.Row.BackColor = Color.Red;
        }
    }
}

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound"></asp:GridView>
