you can use a asp:RegularExpr essionValidator to validate file extensions

a sample regular expression for XSL and CSV is

^[0-9A-Za-z_ ]+(.[xX][lL][sS]|.[cC][sS][vV])$

i am not good in regular exps, following site got lot of samples

Well, the reason could be that the Regular expression you are using is wrong.
You may want to test the expression with a RegularExpressi on tester to see
if it works.

I have used RegularExpressi onValidator with file upload , in the past and it
used to work. Do not have access to the code now to post sample

We've recently moved an application from a W2K server to a Windows 2003 server with IIS 6.0 and in the process managed to lose the ability to handle file uploads. I've managed to identify that this is not specific to IIS 6.0 since we have another server that doesn't give me any problems in this respect. The test program below illustrates the problem. The Page_Load method never resolves the IsPostBack property to true and the...

Hi there, When adding a "File Field" HTML control to an aspx page to facilitate file uploading, the following occurs: 1. You select a file that is larger than the allowed size limit. 2. Once the user selected the too large file, the page is redirected to a "page not found" error page. 3. This is as per the docs, but my question is:

I would like to give my user the option to browse his files (like the simple fileUpload control do) and after selecting the file (and when the fileUpload control hold in his text box the full path and file name) I want to press another button and get the path+file name as a string. I want to do this with out actually upload the file. I use the fileupload just for his browsing option.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
