Hi. i would like to find out if there is an cleaner and easier way for the file extension validation other than using AllowedFileExtension.

As the allowed file extension is alot and i only want to block extension like exe, sql, bat. is there any way to achieve this?

i want the validation to automatically fired like when used with the AllowedFileExtension

Hi,

You can implement your own client-side validation mechanism using the OnClientFileUploading event. You can see this code library for more information.
