    <p>I have a pretty extensive Classic ASP background (using server-side javascript), and my company is finally (FINALLY) making the push towards recoding everything in ASP.Net (using C#). I have a good grasp on good programming practices in Classic ASP and I usually try to make sure I code things the "right" way. I've been reading ASP.Net tutorials and feel like I have a pretty understanding of the basics. I have good discipline about separating client side javascript into external js files, keeping styling outside of the markup in external css files, etc. So, when reading these novice tutorials I understand the concept of the code-behind pages. It makes sense to me to separate the c# code from what will ultimately become the markup for the page. Making &lt; asp:button > objects and the code-behind rules to alter them makes perfect sense.</p> <p>However, I'm having a hard time wrapping my head around how to do something simple like I would have done in Classic ASP like this:</p> <pre><code>&lt;% if (condition) { %&gt; &lt;input type="button" value="click me" onclick="dosomething()" /&gt; &lt;% } else { %&gt; &lt;span&gt;You don't have permission to see the button&lt;/span&gt; &lt;% } %&gt; </code></pre> <p>I'm having a hard time trying to figure out how I'm supposed to fit the conditional stuff you see above into the code-behind page. If I was showing a button under both circumstances, I'd make an <code>&lt;asp:button&gt;</code> object and style it in the code-behind page accordingly - but in the example above I'm only showing the button if the condition is true, and a span block if false.</p> <p>I know that you don't HAVE to put ALL the c# code in the code-behind page. I can use the <code>&lt;% %&gt;</code> tags the same way I would do in Classic ASP. But, if I do that then it seems to me that it lessens the relevance of the code-behind page. For example, I know you can use an external css stylesheet to stylize your page and at the same time use inline styles on individual tags as well. I believe this to be poor practice, however. It makes it difficult to later have to adjust the styles on that element if you don't know whether to look in the markup or in the css file to find the relevant styles affecting that element. </p> <p>It seems to me that the same would hold true for your markup and code-behind pages. Is it just a necessary evil to have to mix the 2, or is there a better way to do what I'm demonstrating above?</p>

    1. COYour question needs some editing. You should make the first paragraph a description of the problem you're facing, not irrelevant background information. Also consider making it clear what the question you're asking is.

    2. COComing from ASP, it may be easier to transition to ASP.NET MVC, instead of web forms. MVC is more syntactically similar to ASP... But I know you probably don't have a lot of control over that :-)

    3. COAs you write that you're finally moving to asp.net from asp classic.. I'd suggest jumping to asp.net mvc ( http://www.asp.net/mvc/mvc4 ), It has much more power and much easier to work with, you have a more asp like alternative (without the mvc part) with the web api: ( http://www.asp.net/web-api ), Don't take a step forward to an old technology ;)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
