ASP.net Repeater get current index, pointer, or counter
提问by Jan W.
the question is really simple. Is there a way to access the current pointer/counter for an asp Repeater control.
问题很简单。有没有办法访问 asp 中继器控件的当前指针/计数器。
I have a list with items and I would like one of the repeaters columns (it repeats and html table) to be something like ...
我有一个包含项目的列表，我希望其中一个中继器列（它重复和 html 表）类似于...
Item 1 | some info
第 1 项 | 一些信息
Item 2 | some info
第 2 项 | 一些信息
... and so on
... 等等
1 and 2 being the counter.
1 和 2 是计数器。

To display the item number on the repeater you can use the Container.ItemIndexproperty.
要在中继器上显示项目编号，您可以使用该Container.ItemIndex属性。
<asp:repeater id="rptRepeater" runat="server">
<itemtemplate>
Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
</itemtemplate>
<separatortemplate>
<br />
</separatortemplate>
</asp:repeater>

Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.
将标签控件添加到中继器的 ItemTemplate。处理 OnItemCreated 事件。

<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
<ItemTemplate>
<div id="width:50%;height:30px;background:#0f0a0f;">
<asp:Label ID="lblSr" runat="server"
style="width:30%;float:left;text-align:right;text-indent:-2px;" />
<span
style="width:65%;float:right;text-align:left;text-indent:-2px;" >
<%# Eval("Item") %>
</span>
</div>
</ItemTemplate>
</asp:Repeater>

背后的代码：
protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
{
Label l = e.Item.FindControl("lblSr") as Label;
if (l != null)
l.Text = e.Item.ItemIndex + 1+"";
}
