问题描述
我怎样才能格式的数据从一个DataBinder.Eval的声明进来一个ASPX页面?
How can I format data coming from a DataBinder.Eval statement in an ASPX page?
例如,我想在网页的特定格式来显示新闻项目的公布日期。我使用ASP.NET 2.0 Repeater控件来显示新闻内容的列表中。
For example, I want to display the published date of the news items in a particular format in the homepage. I'm using the ASP.NET 2.0 Repeater control to show the list of news items.
在code这个是这样的:
The code for this goes like this:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="ObjectDataSource1">
<HeaderTemplate><table cellpadding="0" cellspacing="0" width="255"></HeaderTemplate>
<ItemTemplate>
<tr><td >
<a href='/content/latestNews.aspx?id=<%#DataBinder.Eval(Container.DataItem, "id") %>'>
<asp:Label ID="lblNewsTitle" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "title") %>'></asp:Label>
</a>
</td></tr>
<tr><td>
<asp:Label ID="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate"))%>'></asp:Label>
</td></tr>
</ItemTemplate>
<FooterTemplate></table></FooterTemplate></asp:Repeater>
有没有一种方法我可以打电话与DataBinder.Eval的值作为参数自定义方法(类似下图)?
Is there a way I could call a custom method with the DataBinder.Eval value as its parameter (something like below)?
<asp:Label ID="lblNewsDate" runat="server" Text='<%# GetDateInHomepageFormat(DataBinder.Eval(Container.DataItem, "publishedDate")) )%>'></asp:Label>
如果是,那么我在哪里写GetDateInHomepageFormat方法?我在页面背后的code尝试了,但得到了一个运行时错误?
如果这是不可能的,是有办法做到行内格式化?
If yes, then where do I write the GetDateInHomepageFormat method? I tried out in the code behind page but got a run time error?If this is not possible, is there a way to do inline formatting?
推荐答案
有一个可选的过载的DataBinder.Eval提供格式:
There is an optional overload for DataBinder.Eval to supply formatting:
<%# DataBinder.Eval(Container.DataItem, "expression"[, "format"]) %>
format参数是一个字符串值,使用值占位符替换语法(称为复合格式)是这样的:
The format parameter is a String value, using the value placeholder replacement syntax (called composite formatting) like this:
<asp:Label id="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate", "{0:dddd d MMMM}") %>'</label>
