Good day,

I would like to know if there is any way of allowing dates that are entered into a web form textbox to only be in "dd/Mmm/yyyy" format.

Is this possible? Also is there a drop down date picker for web forms much like there is for win forms?

There are controles that you could buy.
Or make your self.

But there arn't anny (standard in .net) as in VB6,
where you can set a mask. __/__/____

Mostly used are javascript designd calendar's or they use the Calendar object.
Or the 3 dropdown option.

You could make your own check, to see if the input is correct.
