问题 We have a web app(-ish) webform, and we use many custom UserControl s. We load a bunch of them in each view, but we don't want them to render, or even pre-render, until we don't have to use them. Then we set Visible = False in each control and then we use Update Panel s to set it to True whenever the control is needed. The control then shows up correctly.
