使用一个页面中添加和ASP.NET编辑项 [英] Use one page for adding and editing an item in ASP.NET

问题描述

我不认为这个问题是清楚的在这里。

I don't think the question is clear here.

只要我有19种物品在我的系统。我有19页每一个让我添加特定类型的新项目。

Simply I have 19 types of items in my system. and I have 19 pages each one allow me to add a new item of specific type.

添加新项页和编辑现有项目页面中，彼此非常相似..所有我需要的是隐藏/显示一些控件。

The "Add New Item" page and the "Edit an existing Item" page, are very similar from each other .. all what I need is to hide/show a couple of controls.

所以我想我会使用查询字符串来定义我们如何将使用的页面，如果有新的那么一切都将保持不变，如果它用于编辑然后我会改变文本属性的一对夫妇的标签，并显示一些额外的文本框和DropDownLists。

so I thought I'd use QueryString to define how we'll be using the page, if new then everything will remain the same and if it's used for "editing" then I'll change the Text properties for a couple of labels and show some extra TextBoxes and DropDownLists.

我能做到这一点的几种方法，但是这将是一个烂摊子。我希望有人能提出一个办法做到这一点保持在我的一个很好的设计和架构。

I could do this in a several ways but it will be a mess. I was hoping that someone could propose a way to do this keeping in my a good design and architecture.
