The original user control, but maintenance is too trouble, then write a custom control, better maintenance, easy to use. This control is a time control, selecting time, month, day, hour, minute, and second by drop-down list box. Atternuration, provide the starting year of the optional time. The source code is as follows: use system; use system.Web.ui; use system.Web.ui.WebControls; use system.componentmodel; using system.componentmodel.design;
Namespace userTime {///
