<pre><code>public string FirstName {

| <p>Two of the big problems with direct access to variable inside class (field/attribute) are: </p>

<p>I have a couple of triggers on a table that I want to keep <strong><em>separate</em></strong> and would like to priortize them.</p>
<p>I could have just one trigger and do the logic there, but I was wondering if there was an easier/logical way of accomplishing this of having it in a pre-defined order ?</p>
| <p>Use sp_settriggerorder. You can specify the first and last trigger to fire depending on the operation.</p>

<p>I've been trying to create a custom control that works exactly like the Panel control except surrounded by a few divs and such to create a rounded box look. I haven't been able to find a decent example of how to do this. </p>
<p>I need to be able to place text and controls inside the control and access it directly ... | <p>There are two ways to do this. One is to implement <code>INamingContainer</code> on your control, and it takes a lot of effort.</p>
<p>The other way is to inherit from Panel, and override the RenderBeginTag and RenderEndTag methods to add your custom markup. This is easy.</p>

<p>How do I create an asp:Menu that has a horizontal submenu rather then a vertical one while keeping the top menu horizontal?</p>
| <p>You may want to look into using the <a href="http://www.codeplex.com/cssfriendly" rel="nofollow noreferrer">CSS Friendly Adapters</a>. The Menu adapter will render the asp:Menu control using semantic HTML (in this case an unordered list) instead of tables, which makes it much easier to apply CSS to make it do whatev... | <p>The asp.net menu just generates a table.

<p>When posting example code or filing bug reports based on a real production app, it would be helpful to have some way to change the table and column names to not potentially give away information about the internals of the app. Doing it by hand without breaking things is time consuming. Does anything automatic exis... | <p>As long as you don't use real data, I don't see what the issue is. Most apps are fairly obvious based on the requirements. ie CRM system = (customer name, address, etc...) or (customer name, addressid, etc.. with some address table with parts of the address, etc...). By knowing your schema I have no idea how you ... | <p>I agree that there's no real need to do so, but if you feel that way, take a look at anonymizers, usually used to protect the data and not the schemas, but you could easily apply those approaches to schemas as well.</p>
