Validating text box6/10/2004 10:48:07 AM

0/0

Many examples of a validating textbox use a composite control with a textbox and a validator(s). To make this truly like a textbox you then need to implement "wrapper" calls for all properties & methods.

Has anyone implemented a validating textbox by inheriting from textbox and adding validation behavior? In this way the properties & methods of TextBox would be inherited. Otherwise it would seem sensible for ASP.net to have validating versions of the input controls since the input control is the dominant control in the composite.

I realise that validators have form (i.e. a label) so they are more than validation logic but we have ended up with a set of custom controls with masses of forwarding calls to the "dominant" control (e.g. the textbox).

Anyone else have this type of issue?

Regards,

Brian
