Hi,

I'm using a RangeValidator on a text input field to make sure that a date
entered in there is in the future.

On my form there is also a DropDownList control. I now want to disable the
text box's RangeValidator when the user selects a particular item from the
drop-down list.

Using AutoPostBack on the DropDownList control and using server-side code
this would be an easy task. But I want to provide the user with improved
website experience and thus I want to disable the RangeValidator depending
on the drop-down list selection using client-side JavaScript code.

Is this possible? And how can I do this? I'm using .NET 1.0 and 1.1.

TIA,
Axel Dahmen

Hi Axel,

Welcome to the ASP.NET newsgroup.

As for the validation control cilentside manipulation question, based on my
experience, for ASP.NET 1.X, there is some clentside script based API for
manipulating ASP.NET validation controls at clientside. It contains the
method for make a certain validation control do validation , or
enable/disable a certain validator, or query the current validation status
of a validator....   Here is a good msdn article which described the
detailed ASP.NET page validation model(serverside and clientside), and the
clientside valication API are also introduced:

Hope this helps.
