That may answer another question that has been driving me crazy today.

I need to check to see if the file size is too large.

The problem is I can't seem to stop it from trying to load the file and then
giving me an error page

I can't seem to stop it. There doesn't seem to be anywhere to put my
try/catch block. I tried putting it around my upload routing that I call
when I do my submit. That is the point at which I look for the size of the
file.

But that doesn't seem to matter.

I have literally ripped out that code (and any that refers to my upload
objects ID).

<input id="MyFile" style="width:300px" type="File" runat="Server">

and now my submit buttons event does nothing:

Sub SaveChanges_Click(s as Object, e as ImageClickEventArgs)
End Sub

And it still tries to load the file when I hit the submit button.

Why and how can I test for the size of the file to give the user a warning
that the file is too large?

Thanks,

Tom
