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

Question

Is there a way to comment out markup in an .ASPX page so that it isnt 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. Any suggestions would help

Answer 1

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>

Answer 2

<%--
            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”) %>     
--%>

Answer 3

<%-- not rendered to brower --%>

Answer 4

Yes, there are special server side comments: <%-- Text not sent to client --%>

Answer 5

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 Macka's answer :-)

Bonus answer: The keyboard shortcut for commenting out anything in VisualStudio 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.
