I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.

What is the best way to go about creating a custom framework for asp.net?
We have several enterprise level asp.net ecommerce websites all running from completely seperate code bases. What I'd like to do is standardise the common components (session management/urlrewriting/surge control etc) and integrate them into the .net framework at the highest level possible and in a way that my developers cannot (easily) make changes.
I've considered creating a common assembly and just referencing that in each of the solutions but this still relies on the developer wiring up the httphandlers/modules and implementing the basepage design pattern for each individual page/masterpage.
What I would like to have is a mapping between a custom file extension to a class that is not System.Web.UI.Page but a class of mine that inherits from System.Web.UI.Page.
i.e.:
*.aspx -> System.Web.UI.Page *.my -> My.Package.MyClass (inherits from System.Web.UI.Page)
I know I can map any extension to be treated like .aspx but I can't find the way to do what I have in mind.
Excel cannot open the file "Report.xlsx" because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file
Possible Duplicate: How do I Validate the File Type of a File Upload?
i would like to add file extension for filtering to file upload control in my asp.net page.and do validation on client side.how can i set file extension dynamically..ex:images only(.jpg;.png;*.gif;).
Is there a way to specify a file extension for ASP.NET upload control? E.g. I want to upload images with jpg and png extensions only.I can implement this easily for a windows application, but struggling with ASP.Net
I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension.
I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension.
First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests?
Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way?

Okay, maybe it's a bit pedantic, but do ASP.NET user controls HAVE to have an ascx extension?
My reason for wanting to know this is purely academic. I made the statement to someone that they usually have an ascx extension, but then I had the curious thought of if that was always true or not.
I need to set file extension precedence. I want the browser to show default.html before default.aspx. Is there a way to set this up in a web.config file?
I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.
Actually i am using JavaScript validation for Image or Word or Excel File & its working perfectly. My aim is making its full professional.
For Example When you use Photoshop and open any file you see only those extension which are applicable for Photoshop i.e. jpg, jpeg bmp, psd, png etc. You never see .doc, .xls or any other which are not open with Photoshop. This is i want to do, When i open for an Image it should show only Image Type file extension in file type By default its its showing All Files, As i use extension validation in JavaScript, it never accept .doc or .xls files in Image Type Validation but it will show. I want only that file type show for which i open.
