Several methods of time formatting in ASP.

1. Data Control Binding Format Date method:
<asp:boundcolumn datafield= "Addtime" headertext= "Add Time" dataformatstring= "{0:yyyy-mm-dd HH:mm}></asp: Boundcolumn>
<asp:boundfield datafield= "Addtime" headertext= "Add Time" dataformatstring= "{0:yyyy-mm-dd}"/>

2. Use DataBinder.Eval for data binding:
DataBinder.Eval (Container.DataItem, "Addtime", "{0:YYYY-MM-DD}")

3. Convert the date display format directly with the ToString method:
DateTime.Now.ToString ("Yyyy-mm-dd HH:mm:ss")

4. Use the string class to convert the date display format:
String.Format ("{0:yyyy-mm-dd}", DateTime.Now)

5. Convert the date display format using the DateTime.Parse method
DateTime.Parse ("2012-2-22"). ToString ("Yyyy-mm-dd")

6. Convert the date display format using the Convert.todatetime method:
Convert.todatetime ("2012-12-21"). ToString ("Yyyy-mm-dd")
