RegularExpressi onValidator

Ken Grimmett

I have added a REV to an input type of file. I want to make sure that the
only file type that is allowed is a .gif, .jpg, or .jpeg. I develop my site
on my laptop which is running Win XP Pro and my site is hosted on a Win 2000
Advanced server. Here is my problem. When I test it on my local host of
the XP Pro machine the validator works. When I migrate it to the W2K box it
doesn't work. There is no error that is displayed. Is anyone aware of
this. Not sure if it makes a difference or not but the code is in a control
that is displayed.

Here is the code
<%@ import Namespace="ASPN ET.StarterKit.C ommunities" %>
<%@ Register TagPrefix="comm unity" Namespace="ASPN ET.StarterKit.C ommunities"
Assembly="ASPNE T.StarterKit.Co mmunities" %>

Do you have a ValidationSumma ry that you are using? Also, in your code
behind, if you want to validate on the server, you should explicitly do a
Page.Validate() , followed by an if (Page.IsValid) {...}.

For client side validation, you also need to make sure you have run
aspnet_regiis on the specific site you are installing to, and you need to do
this again for each new web site that you create on the server. This
installs the script libraries that are used by validation.

However, when used within a RegularExpressionValidator, it always returns false. Has anyone else had issues with the RegularExpressionValidator not correctly parsing a regular expression?
