ASP.NET DataList控件 - 定义＆QUOT;列/行＆QUOT;重复水平和使用流布局时 [英] ASP.NET DataList - defining "columns/rows" when repeating horizontal and using flow layout

问题描述

下面是我DataList控件：

Here is my DataList:

<asp:DataList id="DataList" Visible="false" RepeatDirection="Horizontal" Width="100%" HorizontalAlign="Justify" RepeatLayout="Flow" runat="server">
        [Contents Removed]
</asp:DataList>

这生成具有包裹在一个跨度的每个项目的标记。从那里，我想每个跨度的闯入了三列行。理想情况下，我想是这样的：

This generates markup that has each item wrapped in a span. From there, I'd like to break each of these spans out into rows of three columns. Ideally I would like something like this:

<div>
 <span>Item 1</span>
 <span>Item 2</span>
 <span>Item 3</span>
</div>
<div>
 <span>Item 4</span>
 <span>Item 5</span>
 <span>Item 6</span>
</div>
[etc]

我能得到这个最接近的是设置RepeatColumns为3，然后一个＆LT; BR＆GT; 在DataList控件每三个项目后插入

The closest I can get to this is to set RepeatColumns to "3" and then a <br> is inserted after every three items in the DataList.

 <span>Item 1</span>
 <span>Item 2</span>
 <span>Item 3</span>
<br>
 <span>Item 4</span>
 <span>Item 5</span>
 <span>Item 6</span>
<br>

这让我的样的的接近，但真的没有做的伎俩 - 我仍然无法控制布局，我想顺便能

This gets me kind of close, but really doesn't do the trick - I still can't control the layout the way I'd like to be able to.

任何人都可以提出一个方法，使这更好​​的？如果我能实现上面的例子 - 这将是完美的，但是我会接受一个不太优雅的解决方案，以及 - 只要它比更灵活＆LT; BR＆GT; （例如插入＆LT;跨度类=清除＆GT;＆LT; / SPAN＆GT; 而不是＆LT; BR＆GT; ）。

Can anyone suggest a way to make this better? If I could implement the above example - that would be perfect, however I'd accept a less elegant solution as well - as long as its more flexible than <br> (such as inserting a <span class="clear"></span> instead of <br>).

推荐答案

如果你真的需要使用一个DataList出于某种原因，而不是实现这个作为一个中继器，你可以尝试做这样的事情：

If you really needed to use a datalist for some reason instead of implementing this as a repeater, you can try doing something like this:

<asp:DataList ID="dataList" runat="server" RepeatDirection="Horizontal" Width="100%" HorizontalAlign="Justify" RepeatLayout="Flow" OnItemDataBound="dataList_ItemDataBound">
    <HeaderTemplate>
        <div>
    </HeaderTemplate>
    <SeparatorTemplate>
        </div><div>
    </SeparatorTemplate>
    <ItemTemplate>
        <%# Container.DataItem %></ItemTemplate>
    <FooterTemplate>
        </div></FooterTemplate>
</asp:DataList>

protected void dataList_ItemDataBound(object sender, DataListItemEventArgs e) {
    if (e.Item.ItemType == ListItemType.Separator) {
        if ((e.Item.ItemIndex + 1) % 3 != 0) {
            e.Item.Controls.Clear();
        }
    }
}
