Please help to understand this RegEx statement in details. It's supposed to validate filename from ASP.Net FileUpload control to allow only jpeg and gif files. It was designed by somebody else and I do not completely understand it. It works fine in Internet Explorer 7.0 but not in Firefox 3.6.
<asp:RegularExpressionValidator id="FileUpLoadValidator" runat="server"
ErrorMessage="Upload Jpegs and Gifs only."
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.jpg|.JPG|.gif|.GIF)$"
ControlToValidate="LogoFileUpload">

I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?
In my project requirement user wants to enter a manual entry if they can not find an item in the drop down list.
Right now what I am doing is:
I set the dropdown list autopost back true and on selectedchanged event I am hiding the drop down list and showing a text box to enter a manual entry...
This is working perfect and no problems..
but the drop down list needs to change to a text box on only selecting a "unknown" option in the list...all other list items are doing unnecessary post back to the server with no use...

ControlToValidate="fileUpEx"></asp:RegularExpressionValidator>
<asp:FileUpload ID="fileUpEx" runat="server" />
Whatever file I pick, this throws the validator even if the file is an image file,
