VB.NET Repeater 无需数据源的简单数据绑定
我有一个表单必须是网页上的转发器。 我有一个数字参数,它告诉我要添加多少个额外的客户详细信息。 在此页面中,我有一个转发器控件,需要将项目重复设定的次数。 对于每个项目,都有一组需要附加 id 的输入框。 我需要绑定的只是每个附加输入框的数字,即 <% #id %>
。 我不知道如何在没有特定数据源的情况下设置简单的数据绑定,但只是在循环中构建一个。

I've got a form that has to be a repeater on a webpage. I have a number parameter that tells me how many additional customer details are to be added. In this page I have a repeater control that needs to repeat items a set number of times. For each item there is a set of input boxes that needs an id appended to it. All I need to bind is a number for each additional input box ie <% #id %>
. I dont know how to set up simple databind without a specific datasource, but just build one in a loop.

这是重复这些项目的方法。 在页面加载事件中,添加以下内容:
重复器项目将按数组中的元素数量重复。 在本例中,有 3 个元素。 数组的实际内容并不重要,重要的是元素的数量。
编辑:我不太了解VB.NET,但我认为这应该可行
Here's a way to repeat the items. In your page load event, add the following:
The repeater items will be repeated by the number of elements in the Array. In this case, there are 3 elements. The actual contents of the array don't matter, just the number of elements.
EDIT: I don't know VB.NET that well, but I think this should work
