Requiredfieldvalidator?

[js]

Hi,

how to use Requiredfieldvalidator Control to check a multi selection
listbox?
the listbox's return value is a require field. thanks.

What exactly is your problem, can't you just set the controltovalidate
property on the validator to the name of your listbox control?

Thanks Michael.
I have set it.

I works for other control, not multiple selection listbox?
