But the problem I ran into today was having Page.FindControl() not work as expected.</p> <h3 id="problem">Problem</h3> <p>Page.FindControl() can be misleading. A developer without understanding the situation could assume FindControl() will return a control found within that page. <em><strong>This is completely wrong.</strong></em> The reason this does not work is because Page does not have its own FindControl() function. It actually <em><strong>inherits</strong></em> this from Control, because Page inherits control. So FindControl() is really more like a FindChildrenControls(), and it is <em><strong>not</strong></em> recursive.</p>
