I was however informed in the comments that by overriding the NamingContainer property the control loses the ability to read its value from the PostBack data.

Since the controls I developed were not meant to to be used in a postback scenario, this wasn’t a big problem for me.

Fast-forward a couple of years and here I am, wondering why post back does not work in one of my projects

Anyway, I looked at the link provided by Alex, where Rick Strahl talks about overriding the ClientId and the UniqueId properties instead of NamingContainer.

In a standard web control, the two properties ClientID and UniqueID are mapped, respectively, to the id and name properties of the HTML control generated.

Since most (all? ) JS frameworks use the id property to access the varius HTML elements and the PostBack mechanism uses the name property, I think the “best of both worlds” solution is to only override the ClientId:

<p><span class="kwrd">public</span> <span class="kwrd">class</span> NiceTextBox : System.Web.UI.WebControls.TextBox
{
    <span class="kwrd">public</span> <span class="kwrd">bool</span> UseNamingContainer { get; set; }
</p><p>    <br />    <span class="kwrd">public</span> <span class="kwrd">override</span> <span class="kwrd">string</span> ClientID
    {
        get
        {
            <span class="kwrd">if</span> (<span class="kwrd">this</span>.UseNamingContainer)
                <span class="kwrd">return</span> <span class="kwrd">base</span>.ClientID;
            <span class="kwrd">else</span>
                <span class="kwrd">return</span> <span class="kwrd">this</span>.ID;
        }
    }
}
</p>

Now our NiceTextBox works even during post-back scenarios

The startup menu is simply a folder located under “All programs” in your Start menu. Every program located in this folder is automatically launched when you log into windows.
How do you add an item to the startup menu? The first thing to do is right-click it and choose Open. Now, probably you have a link to the program you would like to launch on your desktop. Just drag and drop your desktop icon inside the startup menu folder and there you have it: your favorite program will now start with windows!

The “Add Bookmark” window pops up. Let’s use “Google Images” as the bookmark’s name and “i” as the bookmark’s keyword.
I usually save my quick searches inside a folder named “Quick Searches”.

Press Ok and you’re done! Now, any time you want to search for an image you just need to type the letter i followed by your search terms in the address bar and you will be taken to the google images results page.
