i have textboxinputmaskbehavior ip address looks follow:

<behaviors:textboxinputmaskbehavior inputmask="{staticresource inputmaskip}" promptchar="0" /> covers values on 3 fields , hence can not see values.
make me confuse is, why value on subnet field appears? doing wrong other 3 fields?

i copied code , runs without errors.
set values (iprange control):
iprange.start = "123.456.789.000"; iprange.end = "123.456.789.000"; iprange.subnet = "123.456.789.000"; iprange.gateway = "123.456.789.000"; result:
i think, problem binding or else, not in control.
one comment. change mask 000.000.000.000 000\.000\.000\.000 because . decimal separator (in country comma, not dot, therefore can take troubles culture support).
