    <p>You're right, it's all about the <strong>page lifecycle</strong>. Dynamically created controls must be re-created at the <code>Page_Init</code> stage, in order to exist <em>before</em> the viewstate binding stage. This means that will have to somehow (using the <code>Session</code>, maybe) store how many <code>textboxes</code> you have created on the previous processing to recreate them. Remind to use <strong>the same ID</strong> and to add them to your control tree (a repeater or something else that you're using).</p> <hr> <p><strong>UPDATE</strong></p> <p>Let me give you a suggestion: 1. Declare a class attribute of type <code>List&lt;TextBox&gt;</code> (let's call it <code>CreatedTextBoxes</code>)</p> <ol> <li><p>Declare a method that receives whatever it needs to create the textboxes. This method must not read anything outside of it's scope. It will simply receive some args, create the textboxes and add them to another control (such as a <code>Repeater</code>). Add each textbox created to <code>CreatedTextBoxes</code></p></li> <li><p>At the dropdown change event, read the option, save it to the <code>Session</code> and call this method</p></li> <li><p>At <code>Page_Init</code>, verify that object at the <code>Session</code>. If it's null or empty, don't do anything. If it has a value, call that same method, passing the same args</p></li> <li>When you need to retrieve that from the dynamically created textboxes, use <code>CreatedTextBoxes</code> and not <code>FindControls()</code></li> </ol>

    1. COSo in the Page_Init stage, do I have to basically run the method where I create the textboxes based on the dropdown selection again? Wouldn't putting this in the Page_Init method cause the page to attempt to create textboxes on the initial visit to the page (before a dropdown selection is made)?

    2. COYes and yes, that's why you have to figure out some "flow control". I'll update the question with a suggestion

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.
