问题
Since .NET 4 its possible to use the <%: %> syntax for HTML Encoding of text.
In a repeater I use the following syntax to display data
<%# DataBinder.Eval(Container.DataItem, "fieldlabel")%>
The only way I know of to encode the output in the repeater is by using "Server.HtmlDecode". Is it possible to use the new <%: %> in a repeater just in combination with databinding so that I can remove the ugly HtlmDecode syntax. Or is an extention method my only option to improved the readability?
回答1:
No it is not possible. The <%# is allowing the evaulation of binding data but it use the basic <% block.
The only thing you can do is recreate the <%: by wrapping your code in Html.Encode.
Eg:
<%# Html.Encode(DataBinder.Eval(Container.DataItem, "fieldlabel")) %>
The <%: is a shortcut and I guess not every variation of the use of the blocks has been captured to include a shortbut. MS probably didn't want to complicate the issue by creating a ton of different symbols to capture the various uses and only support the most common use.
回答2:
As of ASP.NET 4.5 this is possible using the new <%#: %> notation

I think the answer is no, based on this question.

回答4:
It is possible but need to work more:
Please use below syntax
<asp:Literal ID="fieldlabel" runat="server" Mode="Encode" Text='<%#Eval("fieldlabel")%>"></asp:Literal>
