attach regularexpressi onvalidator to a textbox base on dropdownlist selected item?

Hi, all

Is there a way to dynamically attach a regularexpressi onvalidator to a
textbox base on dropdownlist selected item?

Let's say I have a dropdownlist list all contact type - phone, cell,
email ...etc and a textbox that allow user to type in their contact
info. When they choose email, I want attach the
regularexpressi onvalidator of email to the textbox, when the ddl
selected phone, then I want attach phone regExp to the same textbox.

Any help will be appreciated

thanks

I've done this, however, the regular expression validator has to be in
the same container as the listbox is to work. I don't have the code
for this as I've replaced all my validators with custom validators and
have moved the page validation to a single central errorchecking method
in my code behind.

But, it should just be a matter of specifying the control name of the
listbox to validate in the validator property sheet and selecting one
of the Microsoft regular expression templates for the regular
expression.

And when a user types something in the TextBox and exits the control, the DropDownList item should be changed to that value, showing the corresponding customer name. I am new to JS so I...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
