Form post doesn't contain textbox data [ASP.NET C#]
<p>I have several "ASP:TextBox" controls on a form (about 20).  When the form loads, the text boxes are populated from a database.  The user can change the populated values, and when they submit the form, I take the values posted to the server and conditionally save them (determined by some business logic).  All but 1 of the text boxes work as intended.</p>

<p>The odd box out, upon postback, does not contain the updated value that the user typed into the box.  When debugging the application, it is clear that <strong>myTextBox.Text</strong> reflects the old, pre-populated value, not the new, user-supplied value.  Every other box properly shows their respective user-supplied values.</p>

<p>I did find a workaround.  My solution was to basically extract the text box's value out of the Request.Form object:  <strong>Request.Form[myTextBox.UniqueID]</strong>, which does contain the user-supplied value.</p>

<p>What could be going on, here?  As I mentioned, the other text boxes receive the user-supplied values just fine, and this particular problematic text box doesn't have any logic associated to it -- it just takes the value and saves it.  The maindifference between this text box and the others is that this is a multi-line box (for inputting notes), which I believe is rendered as an HTML "textarea" tag instead of an "input" tag in ASP.NET.</p>
