显示带有选定转换的Kentico Repeater HTML属性 [英] Kentico Repeater HTML Properties showing with selected transformation

问题描述

我的HTML信封将我的中继器转换包装在TABLE标记中.在不使用JS的情况下，如何确保此HTML在选定的转换中不可见.我不反对拥有用于所选转换数据的模板，只是不确定如何做到这一点.

My HTML envelope wraps my repeater transformation in a TABLE tag. Without using JS, how do i ensure this HTML isn't visible for the selected transformation. I have no objections to have a template for the selected transformation data, just unsure how to do that.

这是我的转变:

<tr>
   <td><%# FormatDate(Eval("Date")) %></td>
   <td><a href="<%# GetDocumentUrl() %>"><%# Eval("Subject") %></a></td>
   <td><%# Eval("From") %></td>
</tr>

这是我选择的转换:

<section id="memoDetail">
  <h1>Memorandum</h1>
  <ul id="memoHeader">
   <li><span class="headerLabel">To:</span> <%# Eval("To") %></li>
   <li><span class="headerLabel">From:</span> <%# Eval("From") %></li>
   <li><span class="headerLabel">Subject:</span> <%# Eval("Subject") %></li>
   <li><span class="headerLabel">Date:</span> <%# Eval("Date") %></li>
  </ul>
  <div id="memoDetails"><%# Eval("Details") %></div>
</section>

推荐答案

考虑将表格标签从html信封中移出，并有条件地将它们呈现在转换中，如下所示:

Consider moving your table tags from the html envelope and conditionally rendering them inside your transformation like this:

// If this is the first item in the repeater, open the table tag
<%# DataItemIndex == 0 ? "<table>" : "" %>

  // your trasformation code

// if this is the last item in the repeater, close the table tag
<%# DataItemIndex + 1 == DataItemCount ? "</table>" : "" %>

由于这是完全不同的转换，因此将阻止它们出现在您选择的项目转换中.

This will prevent them from appearing in your selected item transformation since it's a completely different transformation.

您可能必须将DataItemIndex和DataItemCount属性放在Eval()方法中.自从我从事ASCX转换以来已经有一段时间了.

You may have to place the DataItemIndex and DataItemCount properties within an Eval() method. It's been awhile since I've worked with ASCX transformations.

看起来您现在可以在ascx转换中使用IsFirst()和IsLast()方法:

Looks like you can now use the IsFirst() and IsLast() methods within ascx transformations:

<%# IsFirst() ? "<table>" : "" %>

// transformation code

<%# IsLast() ? "</table>" : "" %>
