单值aspx页面绑定 [英] Single value binding in aspx page

问题描述

我需要几十个来自DB查询属性来填充一个aspx页面。我知道怎么做是对财产控件的文本属性分配在背后这样的code：

I need to populate an aspx page with dozens of properties from a db query. What I know how to do is to assign the property to the Text attribute of the control in the code behind like this:

protected void Page_Load(object sender, EventArgs e)
{
    string param = Request.QueryString["param"];
    // p will have dozens of properties
    M.P p = new M.P(param);
    aLabel.Text = p.aProperty;
    anotherLabel.Text = p.anotherProperty;

和在ASPX code：

And in the aspx code:

<asp:Label ID="aLabel" runat="server"></asp:Label>
<asp:Label ID="anotherLabel" runat="server"></asp:Label>

我想什么做的是只是直接在aspx页面绑定属性，而无需在后面像这样code需要分配：

What I would like to do is to just bind the properties directly in the aspx page without the need to the assignment in the code behind like this:

protected void Page_Load(object sender, EventArgs e)
{
    string param = Request.QueryString["param"];
    M.P p = new M.P(param);
    this.DataBind();

Value of the aProperty: <%# p.aProperty %>
Value of the anotherProperty: <%# p.anotherProperty #>

但我失去了一些东西重要，因为编译器给我的错误名称'P'不会在目前情况下存在。如何使它工作？

推荐答案

您可能有这样的事情（ P 移动财产）

You could have something like this (p moved as property)

C＃

protected M.P p {get; set;}

protected void Page_Load(object sender, EventArgs e)
{
    string param = Request.QueryString["param"];
    p = new M.P(param);
}

ASPX

<asp:Label ID="aLabel" runat="server"><%= p.aProperty %></asp:Label>
<asp:Label ID="anotherLabel" runat="server"><%= p.anotherProperty %></asp:Label>
