C# 如果项目在DataTable中，请选中复选框

背景：我一直在一个asp.net网站（barebones fake Client Management System）上工作，该网站使用C#代码隐藏文件，我正在构建基本表单，以便在SQL数据库中插入新数据和更新现有数据

我有一个表（PatientMedicalHistory），其中包含30多个复选框（不在列表中），用于确定我们首次通过存储过程创建新病历时患者表示患有哪些“疾病”。数据存储为组合主键（PatientId int+AilmentId int），以避免重复。潜在的疾病存储在另一个表（Ailments）中，该表包含AilmentId int和AilmentDescription varchar（50）

对于这个表，我可能应该使用不同的模式（1个组合表中每个疾病的位列），但这样做会为将来添加新的“疾病”留下空间

问题：当使用sqlcommand根据PatientId从PatientMedicalHistory表中提取一组患者记录时，我希望遍历当前选定记录的列表，并相应地选中每个相应的复选框

代码：

    pIdstring = ("SELECT ailmentId FROM dbo.PatientMedicalHistory WHERE PatientId = " + pId.ToString());
    cmd = new SqlCommand(pIdstring);
    DataTable dt = new DataTable();
    cmd.Connection = conn;

    using (conn)
    {
        using (cmd)
        {
            conn.Open();
            using (SqlDataReader drCbox = cmd.ExecuteReader())
            {
                dt.Load(drCbox);
                //Need to check all checkboxes that are contained in this datatable.
            }

        }
    }

    }

您是否考虑过使用asp

GridView

控件而不是html表？然后可以在

rowDataBound

事件处理程序中设置复选框状态

---

当然，它会让您面临一系列潜在的其他问题（GridView是一个很难处理的问题！），但可能值得一试。

从datatable到复选框的映射是什么？另外，我建议使用SqlCommand.Paramaters进行硬编码查询。您是否考虑过创建一个可以透视数据的存储过程？短期解决方案是，更改复选框的ID属性，以将AilmentID包含在可预测的模式中，如“AilmentCbox_1”“AilmentCbox_2”“AilmentCbox_3”等，以便将控件与数值匹配。长期解决方案，将行号和列号列添加到您的疾病表中，以便从数据库动态生成复选框控件，在您的ASPX页面中没有硬编码。我的印象是，通过将SELECT的结果放入一个单列数据表中，我将能够遍历该数据表，并且只要数据表中存在“I”，就可以选中带有名称的复选框（即chkBox_I，其中I是当前迭代）。是的。但是，您的示例代码没有chkBox_i形式的复选框，它更像是一个疾病别名（“贫血箱”、“肺气肿箱”、“低血糖箱”等）。此外，“i”必须是疾病id，而不仅仅是结果集的行号。我确实简单地看了一下，但不确定如何正确地实现它-/在这种情况下，如果你能得到你的cu，可能会比它的价值更麻烦
