如何将参数从一页传递到另一页? [英] How to pass parameters from one page to another?

问题描述

您好，在按A页上的确定按钮时，在B页上出现了确定的标题.

例如:

我按下页面A上的"MenCollectionOptic"按钮，在页面B的Label控件中获得"MenCollectionOptic"文本标题.
(或)
按下页面A上的"WomenCollectionSun"按钮，在页面B上的Label控件中获得"WomenCollectionSun"文本标题.

这是我在A页中的ASP代码:

Hello,on pushing determined button on the page A, appeared determined title on page B.

For Example:

I press button "MenCollectionOptic" on page A, i get "MenCollectionOptic" text title in Label control,on page B.
(or)
I press button "WomenCollectionSun" on page A, i get "WomenCollectionSun" text title in Label control,on page B.

Here is my ASP code in page A:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
   <asp:Repeater ID="rpt1" runat="server" onitemdatabound="rpt1_ItemDataBound" 

        onitemcommand="rpt1_ItemCommand">    
   <ItemTemplate>             
     <div><%# Eval("Name") %>-<%# Eval("CollectionType")%><asp:Button ID="btn1" runat="server" Text="edit item"  PostBackUrl="~/B.aspx" EnableViewState="True"/>

      </div>
      <br />     
   </ItemTemplate> 
   </asp:Repeater> 
    <br />
   
Here is the code behinde:


<pre lang="c#">

    public partial class _Default : System.Web.UI.Page
    {
          List<GlassesCollection> gc= BL.Example.GetCategory() ;

        protected void Page_Load(object sender, EventArgs e)
        {
            rpt1.DataSource = gc;
            rpt1.DataBind();
        }

        protected void rpt1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {

         Button btn = (Button)e.Item.FindControl("btn1");
         btn.CommandArgument = DataBinder.Eval(e.Item.DataItem,"CollectionID").ToString();
       }
}    

我的想法是，页面B后面的代码获取选定的collectionID，并在Label事件中使用它来显示适当的标题.
我的问题是，如何才能将collectionID从后面的A页代码传递到后面的B页代码?

My idea is that code behind of page B gets the chosen collectionID and use it in Label''s event to display appreate colletion title.
My quiestion is how can collectionID can be passed from page A code behind to page B code behind?
Thank you in advance!

推荐答案

您可以通过两种方式解决此问题-1)使用表单参数，或2)使用会话.

You can solve this problem in 2 ways - 1) Use of form parameters, or 2)Use session.

HI，

如果您直接重定向到页面B，则可以使用查询字符串将值传递到页面A到页面B


如
这在A页中

If you are directly redirected to page B You can use query string to pass your values to Page A to Page B


as
this is in page A

Response.Redirect("pageB.aspx?collectionID ="+ yourvalue+" );

在B页:
您可以通过
检索collectionID值

in Page B:
You can retrive collectionID value by

Request.QueryString[0];

或

or

Request.QueryString["collectionID "]

问候，

在第2页中用于捕获第1页中所需的所有数据，请创建一个构造函数，然后在page1中为page2的类创建obj并通过它发送.类似这样的东西

in page 2 for capturing all the data you want from page 1 create a constructor and in page1 create obj for page2 s class and send through it.some thing like this

/////////////////////page1 
class page1class{

//pass your objects
page2class obj = new page2class(MenCollectionOptic.text,WomenCollectionSun.text)


} 

//////////////////page2
class page2class{

//constructor

void page2class(string MenCollectionOptic,string WomenCollectionSun )
{

 this.MenCollectionOptic=MenCollectionOptic;
this.WomenCollectionSun= WomenCollectionSun;
}
