我尝试在 aspx 中编写数据网格。在我的数据库中有一个名为“PROJECT_NAME”的列。我想要这些列在我的数据网格中，然后我添加第二列（编辑框）来为每个项目添加值。这一切都在网格视图中，我在表单中添加了按钮。当我按下按钮时，我如何了解哪些列值属于哪个项目？

我的意思是，例如

  1. 行值：A 项目 2 列值：50
  2. 行值：B 项目 2 列值：60
  3. 行值：C 项目 2 列值：70

我想知道当我按下按钮 1 时。项目值 50 我怎么能理解这个？

这是我的 aspx 代码：

在 Button1_Click 内部，您需要遍历 GridView 中的所有行并在每一行上执行 FindControl 以获取标签和文本框。从中您可以确定文本框中的 PRJ_PROJECT_NAME 和值是什么。

这是一个例子：

默认.aspx

<asp:GridView ID="gvData" runat="server" AutoGenerateColumns="false">
  <Columns>
    <asp:TemplateField>
      <ItemTemplate>
        <asp:Label ID="lblLabel" runat="server" Text='<%# Bind("Number") %>' />
      </ItemTemplate>          
    </asp:TemplateField>
    <asp:TemplateField>
      <ItemTemplate>
        <asp:TextBox ID="txtData" runat="server" Text='<%# Bind("Value") %>' />
      </ItemTemplate>
    </asp:TemplateField>
  </Columns>
</asp:GridView>
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" />

默认.aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
  if (!IsPostBack)
  {
    // Create some fake data and bind it to the gridview
    var data = new List<TheData>();

    foreach(var num in Enumerable.Range(1, 4))
    {
      var newData = new TheData();

      newData.Number = num.ToString();
      newData.Value = num;

      data.Add(newData);
    }

    gvData.DataSource = data;
    gvData.DataBind();
  }
}

protected void btnSubmit_Click(object sender, EventArgs e)
{
  for (var index = 0; index < gvData.Rows.Count; ++index)
  {
    var row = gvData.Rows[index];
    var lblLabel = row.FindControl("lblLabel") as Label;
    var txtData = row.FindControl("txtData") as TextBox;

    //Here is where the values are grabbed, at this point you can do what you need to.
    var number = lblLabel.Text;
    var value = txtData.Text;
  }
}

我之前使用的一种解决方案利用了按钮的 CommandArgument 属性。您可以设置 CommandArgument='<% Eval("ColumnValueYouWant") %>' 并且每个按钮都将获取其所在行中列的值。然后，在单击事件中，您可以将对象发送方解析回 Button 并访问 CommandArgument 值。
