Is there a way to comment out markup in an .ASPX page?

问题

Is there a way to comment out markup in an .ASPX page so that it isn't delivered to the client? I have tried the standard comments  but this just gets delivered as a comment and doesn't prevent the control from rendering.

回答1:

<%--
            Commented out HTML/CODE/Markup.  Anything with
            this block will not be parsed/handled by ASP.NET.

            <asp:Calendar runat="server"></asp:Calendar> 

            <%# Eval(“SomeProperty”) %>     
--%>

Bonus answer: The keyboard shortcut in Visual Studio for commenting out anything is Ctrl-KC . This works in a number of places, including C#, VB, Javascript, and aspx pages; it also works for SQL in SQL Management Studio.

You can either select the text to be commented out, or you can position your text inside a chunk to be commented out; for example, put your cursor inside the opening tag of a GridView, press Ctrl-KC, and the whole thing is commented out.

FYI | ctrl + K, C is the comment shortcut in Visual Studio. ctrl + K, U uncomments.

<%-- not rendered to browser --%>

回答5:

Yes, there are special server side comments:

<%-- Text not sent to client  --%>

回答6:

I believe you're looking for:

<%-- your markup here --%>

That is a serverside comment and will not be delivered to the client ... but it's not optional. If you need this to be programmable, then you'll want this answer :-)

While this works:

<%-- <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ht_tv1.Default" %> --%>
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Blank._Default" %>

This won't.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" <%--Inherits="ht_tv1.Default"--%> Inherits="Blank._Default" %>

So you can't comment out part of something which is what I want to do 99.9995% of the time.

Another way assuming it's not server side code you want to comment out is...

<asp:panel runat="server" visible="false">
    html here
</asp:panel>
