如何将查询字符串传递给用户控件 [英] How to pass query string to user Control

问题描述

我正在尝试开发用户控件.

在其中，我正在使用AjaxModalPopextender.

我想显示该用户控件中的值列表.

但是我想对大多数表单使用此控件，所以我正在创建一个动态用户控件.

因此，任何人都可以建议如何通过使用querystring或任何其他方式将参数传递给用户控件.


预先感谢

推荐答案

将数据传递给用户控件的最佳方法是拥有公共属性.例如:

The best way to pass data to a user control would be to have public properties. For example:

public partial class PopupControl : System.Web.UI.UserControl
{
   public string DisplayValues { get; set; }
}

因此，现在当您使用此控件时，您可以执行以下操作:

So, now when you are using this control, you can do something like:

<uc:popupcontrol  runat="server" id="popup1" displayvalues="some values" xmlns:uc="#unknown" />

同样，如果您正在动态创建这些控件(如您在问题中所述):

Similarly, if you are dynamically creating these controls (as you say in your question):

PopupControl popup = LoadControl(src);
popup.DisplayValues = "some values";

本文相当详细地对此进行了解释-动态加载ASP.NET用户控件 [ ^ ]

当然，也可以像在aspx页面中一样在用户控件中访问任何查询字符串，但是更干净的方法是使用用户控件属性.

希望这会有所帮助！

This article pretty much explains this in detail - Dynamic Loading of ASP.NET User Controls[^]

Of course any query string can also be accessed in a user control just like in a aspx page, but the cleaner way of doing this is with user control properties.

Hope this helps!
