[英]Server tags not working inside asp controls
Alrighty to make this quick: 可以快速进行以下操作:
set a and set b have flags StartDate="<%# hfStart.value%>" EndDate="<%# hfEnd.value%>"
set a和set b具有标志
StartDate="<%# hfStart.value%>" EndDate="<%# hfEnd.value%>"
set a in the item template of a grid view column works like a charm 在网格视图列的项目模板中设置a就像一个超级按钮
set b in the HTML table doesn't appear to work at all HTML表格中的set b似乎根本不起作用
What gives? 是什么赋予了?
So far I have tried other server tags with the same code inside but I am obviously missing the salient detail. 到目前为止,我已经尝试了其他具有相同代码的服务器标签,但是显然我遗漏了明显的细节。 Why does one work and not the other?
为什么一个起作用而不另一个起作用?
UPDATE: Tried 更新:尝试过
CDate(hfstart.value).ToString
with <%: and <%= tags CDate(hfstart.value).ToString
<%= hfstart.value %>
Unless I misunderstand, <%= will fire at the very END of the asp.net life cycle stopping it from being useful in this context. 除非我误会,否则<%=会在asp.net生命周期的末尾触发,从而阻止它在这种情况下有用。
As it turns out you DO need to use <%# %>
within asp tags as others like <% %>
and <%= %>
execute at the end of the ASP.NET life cycle and get spit out the buffer to god knows where. 事实证明,您确实需要在asp标记中使用
<%# %>
,就像其他类似<% %>
和<%= %>
的代码在ASP.NET生命周期结束时执行,并吐出缓冲区,这真是天知道哪里。 When using <%# %>
however, the asp control needs to be DataBound();
但是,使用
<%# %>
时,asp控件需要为DataBound();
at the appropriate time. 在适当的时间。
This happens automatically for controls modeled in the <item template>
tags in the gridview because everything within the gridview is bound on its gridview.DataBound()
command. 对于在gridview的
<item template>
标记中建模的控件,这种情况会自动发生,因为gridview中的所有内容都绑定在其gridview.DataBound()
命令上。
Could it be because you're using the <%# %>
tags which are for data binding? 可能是因为您使用的是用于数据绑定的
<%# %>
标签吗? This would explain why they work in the GridView, because it supports data binding. 这将解释它们为什么在GridView中工作的原因,因为它支持数据绑定。
However in a basic HTML table you should use <% %>
tags instead, or <%= %>
to call a method. 但是,在基本HTML表中,应改为使用
<% %>
标记,或使用<%= %>
来调用方法。
