Question

Can I do something like this in the markup of an asp.net page, based off the ‘Define DEBUG constant’ setting?

#IF (DEBUG) THEN   <asp:TextBox ID='TextBox1' runat='server'>You're in debug mode</asp:TextBox> #END IF 

Answer 1

The close as I can get is:

<asp:Literal id='isDebug' runat='server' /> <script runat='server'>     void Page_Load()     { #if DEBUG         isDebug.Text = 'You're in debug mode'; #endif     } </script>  

This would give you problems if you wanted to have anything else in your Page_Load() event; the literal code above only works if the page/control has no code behind.

If I needed to do this, I would encapuslate the above code into a user control and include that control in the pages of interest.

My test user control looks like this:

<%@ Control Language='C#' AutoEventWireup='true'  %> <asp:Literal id='isDebug' runat='server' /> <script runat='server'>         void Page_Load()         { #if DEBUG                 isDebug.Text = 'You're in debug mode'; #endif         } </script>
