如何访问从一个页面到另一个页面的复选框。 [英] How to access a checkbox from one page to other.

问题描述

我在页面'A'中有一个CheckBox，我想访问'B'页面中的Checkbox。



我尝试了什么：



*我通过以下方式访问Page'B'页面'A' -

I have a CheckBox in page 'A' and I want to access that Checkbox in Page 'B'.

What I have tried:

* I'm accessing Page 'A' from Page 'B' by doing the following-

Protected WithEvents A1 As A

*我在Page_Load中声明了一个CheckBox如下：

* I've declared a CheckBox in the Page_Load as following:

Dim chk As CheckBox = CType(A1.FindControl("chk"), CheckBox)

*页面'B'有多个Case语句，我想在其中一个案例中访问CheckBox，我通过执行以下操作使CheckBox可见：

* Page 'B' has number of Case statements and I want to access that CheckBox in one of the Cases, and I'm making that CheckBox Visible by doing the following:

Case "9"

chk.Visible = True

*但是，它不是这样的。我只是希望CheckBox在Page'B'中可见。任何帮助将不胜感激。谢谢！

* But, It's not working that way. I just want the CheckBox to be Visible in Page 'B'. Any help would be greatly appreciated. Thanks!

推荐答案

对于ASP.NET WebForms，您可以使用以下任一方式访问上一页的控件：



Server.Transfer

跨页面PostBack

表格POST



一个例子：https://www.aspsnippets.com/Articles/Access-Previous-Page-controls-in-ASPNet-using- C-and-VBNet.aspx [ ^ ]



或者，您可以存储上一页的值，以便参考他们在另一页上使用：



使用公共属性

使用会话

QueryStrings

For ASP.NET WebForms, you can access controls from previous page using either:

Server.Transfer
Cross-Page PostBack
Form POST

An example: https://www.aspsnippets.com/Articles/Access-Previous-Page-controls-in-ASPNet-using-C-and-VBNet.aspx[^]

Alternatively, you can store the values of the previous page so you can reference them on the other page using:

Using Public Properties
Using Sessions
QueryStrings
