I have written a control that inherits BaseValidator.  If it used by
itself on a page, the control works perfectly fine.
If I drop the RequiredFieldValidator on the same page to evaluate a
different textbox, my control does not work.  But *only* if

Now I am hosting a user control(an assembly in .dll) in IE.
I want to know the difference between this kind of  control and ActiveX
control.
thank you.

I have created a custom control that represents a date-input. It
consists of a textbox and a button which opens a popup calendar.
Now when I have two of those date-inputs, I want to ensure that the
user doesn't enter a date in the second input that is smaller than that

I would like to know whether anybody has any ideas about how to create a
listbox with checkbox appearing besdies all the option text. I thought it
would be easy, but it seems there is no such control in ASP.net. any ideas?
