跨页发布Asp.net [英] Cross Page Posting Asp.net
问题描述
我想从一页到另一页进行交叉张贴，但是我有
主页上的两个按钮，我希望收到帖子的页面
确定单击了哪个按钮:
I would like to do a cross post from one page to another, but I have
two buttons on the main page, and I want the page receiving the post to
determine which button has been clicked:
<body>
<form id="form1" runat="server">
<div>
<asp:Button PostBackUrl="HandlerPage.aspx" ID="Button1"
runat="server" Text="Do This" /><br />
<asp:Button PostBackUrl="HandlerPage.aspx" ID="Button2"
runat="server" Text="Do Something Else" /> </div>
</form>
</body>
HandlerPage.aspx可以测试Page.PreviousPage来查看它是否正在
由交叉点调用，但是如何确定Button1或Button2
被点击了吗?
我现在所能想到的都是令人不快的选择:
1)整理会话对象
2)使用查询字符串
3)查看Request.form并检查Button1的ClientID，如下所示:
HandlerPage.aspx can test Page.PreviousPage to see if it is being
called by a cross post, but how do I determine if Button1 or Button2
was clicked?
All I can think of right now are unpalatable options:
1) Clutter up the session object
2) Use a Querystring
3) Look at Request.form and check the ClientID of Button1 as below:
Button Button1 = (Button)PreviousPage.FindControl("Button1");
Button Button2 = (Button)PreviousPage.FindControl("Button2");
if (Request.Form[Button1.ClientID]==Button1.Text){
Response.Write ("Button1 CLicked");
}
else if (Request.Form[Button2.ClientID] == Button2.Text)
{
Response.Write("Button 2 Clicked");
}
}
后一种策略似乎可行，但我不禁会认为
必须有一种更清洁的方法.
This latter strategy seems to work, but I can''t help thinking that
there must be a cleaner way.
推荐答案
一种明显的方法是将按钮的ID放在URL上.跨页面发布是一个真正的技巧，最好不要这样做.您可以将两个页面"放在一个页面中作为控件.甚至更好的是使用MVC，它比Webforms更好.
The obvious way to do this, is to put the id of the button on the URL. Cross page posting is a real hack, you''d be better off not doing it. You can put both ''pages'' inside the one page as a control. Even better would be to use MVC, which is way better than webforms.
