Hi all,

I am try to trying restrict upload to only .doc files. I have looked through the documentation and was really confused by the syntax. I attempted to use a regular expression validator but it doesn't seem to allow custom regex, unless I don't have the proper syntax. Below is the code for the custom validator I am trying to use. I've set the sub below as a break point and tried stepping through the debugger (in VS.Net ver 7.0.9466), but it doesn't break at that point and the validator summary message box pops up declaring "The only acceptable files for upload are .doc files !" which is the error message I set.

Any suggestions on how to fix this or where to look would be appreciated.

Thanks,

Wes

Sub FileValidation(ByVal source As Object, ByVal args As ServerValidateEventArgs)

Try

If uplFile.Value = "(\w,\W)*\.\d\o\c" Then

args.IsValid = True

End If

Catch ex As Exception

args.IsValid = False

End Try

End Sub

Paul, Thanks for the suggestion. I couldn't get it to work but I did get uplFile.PostedFile.FileName.EndsWith(".doc") = True to work in identifying the file, but I can't get it to work with the custom validator(code below). I've set the ClientValidationFunction property to FileValidation. I've read through the CustomValidator.ClientValidationFunction Property doc but didn't quite understand what they were doing. Can you help.
Thanks,
Wes

Private Function FileValidation(ByVal source As Object, ByVal args As ServerValidateEventArgs)

If uplFile.PostedFile.FileName.EndsWith(".doc") = True Then

reFileType.IsValid = True

End If

Catch ex As Exception

reFileType.IsValid = False

End Try

End Function

Wes, the client validation function should be a piece of Javascript that
exists within the web page (ie. client side). it should be something like
this :-

<script language="javascript">
function FileValidation(oSrc, args)
{
args.IsValid = false;
// do your test for the filename extension which will be in args.value
property
if (args.value.length > 0)
{
// test for .doc extension (I cant remember the javascript for
string manipulations...), pos, substr...?
if (file contains a .doc extnesion)
args.IsValid = true;
}
}
</script>

Note that the above is pseudo code but should give you an idea of how to go
about it.
