I'm trying to build a time picker and I have no idea how to do this using
C#. Any help will be most appreciated.

I have a custom composite control decorated with ParseChildren(false) and PersistChildren(true) because I want to parse the inner
markup for custom controls. That part works fine.
But the "top level" control also contains a series of style properties that I want to persist using ...

Is there possible to use renderbegintag without any tag ? I created a
webcontrol library. The output of control there is span tag. How can i
disable it ? I want to put any tag at html output of webcontrol
library.

Is it possible to programmatically assign a databinding expression to a child control of a composite control. For example:
protected override void CreateChildControls()
{
    Label aLabel = new Label();
