从aspx.cs文件中的ascx文件调用方法 [英] Calling a method from ascx file in aspx.cs file

问题描述

我想从Default.aspx.cs文件中的ShoppingCartControl.ascx.cs文件(用户控件)中调用一个名为AddProductToCart()的方法.在Default.aspx.cs中，我有以下代码:

using System;
using System.Web.UI;
public partial class _Default : Page
{

    protected void ProductControl_AddToCartClick(object sender, EventArgs e)
    {
        ProductControl product = (ProductControl)sender;
}}

其中(Productcontrol)是另一个.ascx.cs文件中的类.
此方法存在于ShoppingCartControl.ascx.cs文件中的ShoppingCartControl类中.

如何在aspx.cs文件中调用此方法?请建议
回复将非常可观！！！！！！！！！！！！！！！！！！

您可以通过以下两种方式之一进行操作:

0)创建一个BasePage类，其中包含多个页面将需要访问的通用方法.

1)创建一个静态类，其中包含所有代码都可以在站点上访问的方法.如果这些方法需要访问特定于页面的变量，则必须将这些变量设置为会话变量，或者将它们作为参数传递给静态方法.

ShoppingCartControl shoppingCartControl = new ShoppingCartControl();
shoppingCartControl.AddProductToCart();

或使用对象的任何扩展实例(如果可用).该方法应根据需要是公共方法或内部方法.

I want to call a method named AddProductToCart() from ShoppingCartControl.ascx.cs file(user control) in Default.aspx.cs file..In Default.aspx.cs,I have the code:

using System;
using System.Web.UI;
public partial class _Default : Page
{

    protected void ProductControl_AddToCartClick(object sender, EventArgs e)
    {
        ProductControl product = (ProductControl)sender;
}}

where (Productcontrol) is a class in another .ascx.cs file.
This method is present in the ShoppingCartControl class which is in ShoppingCartControl.ascx.cs file.

How to call this method in aspx.cs file ? plz suggest
Reply will be highly appreciable !!!!!

解决方案

You can do it one of two ways:

0) Create a BasePage class that holds common methods that more than one page will need to access

1) Create a static class that holds methods that all code can access on the site. If these methods require access to page-specific variables, you''ll have to set those variables as session variables or pass them as parameters to the static methods.

ShoppingCartControl shoppingCartControl = new ShoppingCartControl();
shoppingCartControl.AddProductToCart();

Or use any exixting instance of the object if available and applicable. The method should be a public or internal method based on the needs.
